Subject: [PATCH 03/53] soc: mediatek: Init MT8173 scpsys driver earlier
Some power domain comsumers may init before module_init.
So the power domain provider (scpsys) need to be initialized
earlier too.

Subject: [PATCH 11/53] reset: mediatek: mt2701 reset driver
In infrasys and perifsys, there are many reset
control bits for kinds of modules. These bits are
used as actual reset controllers to be registered
into kernel's generic reset controller framework.

Subject: [PATCH 12/53] ARM: mediatek: Add MT2701 config options for mediatek
SoCs.
The upcoming MTK pinctrl driver have a big pin table for each SoC
and we don't want to bloat the kernel binary if we don't need it.
Add config options so we can build for one SoC only. Add MT2701.

Subject: [PATCH 17/53] clk: add hifsys reset
Hi,
small patch to add hifsys reset bits. Maybe you could add it to the next
version of your patch series. i have teste scpsys and clk on mt7623 today
and it works well.
thanks,
John

+MT8173 xHCI
+
+The device node for Mediatek SOC USB3.0 host controller
+
+Required properties:
+ - compatible : should contain "mediatek,mt8173-xhci"
+ - reg : specifies physical base address and size of the registers,
+ the first one for MAC, the second for IPPC
+ - interrupts : interrupt used by the controller
+ - power-domains : a phandle to USB power domain node to control USB's
+ mtcmos
+ - vusb33-supply : regulator of USB avdd3.3v
+
+ - clocks : a list of phandle + clock-specifier pairs, one for each
+ entry in clock-names
+ - clock-names : must contain
+ "sys_ck": for clock of xHCI MAC
+ "wakeup_deb_p0": for USB wakeup debounce clock of port0
+ "wakeup_deb_p0": for USB wakeup debounce clock of port1
+
+ - phys : a list of phandle + phy specifier pairs
+
+Optional properties:
+ - mediatek,wakeup-src : 1: ip sleep wakeup mode; 2: line state wakeup
+ mode;
+ - mediatek,syscon-wakeup : phandle to syscon used to access USB wakeup
+ control register, it depends on "mediatek,wakeup-src".
+ - vbus-supply : reference to the VBUS regulator;
+ - usb3-lpm-capable : supports USB3.0 LPM
+
+Example:
+usb30: usb@11270000 {
+ compatible = "mediatek,mt8173-xhci";
+ reg = <0 0x11270000 0 0x1000>,

Subject: [PATCH 27/53] soc: mediatek: PMIC wrap: Clear the vldclr if state
machine stay on FSM_VLDCLR state.
Sometimes PMIC is too busy to send data in time to cause pmic wrap timeout,
because pmic wrap is waiting for FSM_VLDCLR after finishing WACS2_CMD. It
just return error when issue happened, so the state machine will stay on
FSM_VLDCLR state when data send back later by PMIC and timeout again in next
time because pmic wrap waiting for FSM_IDLE state at the beginning of the
read/write function.
Clear the vldclr when timeout if state machine stay on FSM_VLDCLR.

Subject: [PATCH 34/53] soc: mediatek: PMIC wrap: split SoC specific init into
callback
This patch moves the SoC specific wrapper init code into separate callback
to avoid pwrap_init() getting too large. This is done by adding a new
element called init_special to pmic_wrapper_type. Each currently supported
SoC gets its own version of the callback and we copy the code that was
previously inside pwrap_init() to these new callbacks. Finally we point the
2 instances of pmic_wrapper_type at the 2 new functions.

Subject: [PATCH 38/53] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and
pwrap_is_mt8173()
With more SoCs being added the list of helper functions like these would
grow. To mitigate this problem we remove the existing helpers and change
the code to test against the pmic type stored inside the pmic specific
datastructure that our context structure points at. There is one usage of
pwrap_is_mt8135() that is ambiguous as the test should not be dependent on
mt8135, but rather on the existence of a bridge. Add a new element to
pmic_wrapper_type to indicate if a bridge is present and use this where
appropriate.

From 7c6b5e5e36ccd9079a2425dc80507447784b9bb2 Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Wed, 20 Jan 2016 09:55:08 +0100
Subject: [PATCH 39/53] soc: mediatek: PMIC wrap: add a slave specific struct
This patch adds a new struct pwrap_slv_type that we use to store the slave
specific data. The patch adds 2 new helper functions to access the dew
registers. The slave type is looked up via the wrappers child node.

+Mediatek MT6323 Regulator Driver
+
+All voltage regulators are defined as subnodes of the regulators node. A list
+of regulators provided by this controller are defined as subnodes of the
+PMIC's node. Each regulator is named according to its regulator type,
+buck_<name> and ldo_<name>. The definition for each of these nodes is defined
+using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are::
+BUCK:
+ buck_vproc, buck_vsys, buck_vpa
+LDO:
+ ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
+ ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
+ ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr,
+ ldo_vrf18, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio

Subject: [PATCH 47/53] regulator: mt6323: Add support for MT6323 regulator
The MT6323 is a regulator found on boards based on MediaTek MT7623 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

+MediaTek Frame Engine Ethernet controller
+=========================================
+
+The frame engine ethernet controller can be found on MediaTek SoCs. These SoCs
+have dual GMAC each represented by a child node..
+
+* Ethernet controller node
+
+Required properties:
+- compatible: Should be "mediatek,mt7623-eth"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the frame engines interrupt
+- clocks: the clock used by the core
+- clock-names: the names of the clock listed in the clocks property. These are
+ "ethif", "esw", "gp2", "gp1"
+- power-domains: phandle to the power domain that the ethernet is part of
+- resets: Should contain a phandle to the ethsys reset signal
+- reset-names: Should contain the reset signal name "eth"
+- mediatek,ethsys: phandle to the syscon node that handles the port setup
+- mediatek,pctl: phandle to the syscon node that handles the ports slew rate
+ and driver current
+
+Optional properties:
+- interrupt-parent: Should be the phandle for the interrupt controller
+ that services interrupts for this device
+
+
+* Ethernet MAC node
+
+Required properties:
+- compatible: Should be "mediatek,eth-mac"
+- reg: The number of the MAC
+- phy-handle: see ethernet.txt file in the same directory.
+
+Example:
+
+eth: ethernet@1b100000 {
+ compatible = "mediatek,mt7623-eth";
+ reg = <0 0x1b100000 0 0x20000>;
+ clocks = <&topckgen CLK_TOP_ETHIF_SEL>,
+ <&ethsys CLK_ETHSYS_ESW>,
+ <&ethsys CLK_ETHSYS_GP2>,
+ <&ethsys CLK_ETHSYS_GP1>;
+ clock-names = "ethif", "esw", "gp2", "gp1";
+ interrupts = <GIC_SPI 200 IRQ_TYPE_LEVEL_LOW>;
+ power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
+ resets = <&ethsys MT2701_ETHSYS_ETH_RST>;
+ reset-names = "eth";
+ mediatek,ethsys = <&ethsys>;
+ mediatek,pctl = <&syscfg_pctl_a>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ gmac1: mac@0 {
+ compatible = "mediatek,eth-mac";
+ reg = <0>;
+ phy-handle = <&phy0>;
+ };
+
+ gmac2: mac@1 {
+ compatible = "mediatek,eth-mac";
+ reg = <1>;
+ phy-handle = <&phy1>;
+ };
+
+ mdio-bus {
+ phy0: ethernet-phy@0 {
+ reg = <0>;
+ phy-mode = "rgmii";
+ };
+
+ phy1: ethernet-phy@1 {
+ reg = <1>;
+ phy-mode = "rgmii";
+ };
+ };
+};

Subject: [PATCH 01/76] clk: make strings in parent name arrays const
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The clk functions and structs declare the parent_name arrays as
'const char **parent_names' which means the parent name strings
are const, but the array itself is not. Use
'const char * const * parent_names' instead which also makes
the array const. This allows us to put the parent_name arrays into
the __initconst section.

Subject: [PATCH 03/76] clk: mediatek: Add reset controller support
The pericfg and infracfg units also provide reset lines to several
other SoC internal units. This adds a function which can be called
from the pericfg and infracfg initialization functions which will
register the reset controller using reset_controller_register. The
reset controller will provide support for resetting the units
connected to the pericfg and infracfg controller. The units resetted
by this controller can use the standard reset device tree binding
to gain access to the reset lines.

Subject: [PATCH 06/76] soc: mediatek: Add infracfg misc driver support
This adds support for some miscellaneous bits of the infracfg controller.
The mtk_infracfg_set/clear_bus_protection functions are necessary for
the scpsys power domain driver to handle the bus protection bits which
are contained in the infacfg register space.

+MediaTek SCPSYS
+===============
+
+The System Control Processor System (SCPSYS) has several power management
+related tasks in the system. The tasks include thermal measurement, dynamic
+voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
+The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
+domain control.
+
+The driver implements the Generic PM domain bindings described in
+power/power_domain.txt. It provides the power domains defined in
+include/dt-bindings/power/mt8173-power.h.
+
+Required properties:
+- compatible: Must be "mediatek,mt8173-scpsys"
+- #power-domain-cells: Must be 1
+- reg: Address range of the SCPSYS unit
+- infracfg: must contain a phandle to the infracfg controller
+
+Example:
+
+ scpsys: scpsys@10006000 {
+ #power-domain-cells = <1>;
+ compatible = "mediatek,mt8173-scpsys";
+ reg = <0 0x10006000 0 0x1000>;
+ infracfg = <&infracfg>;
+ };
+
+Example consumer:
+
+ afe: mt8173-afe-pcm@11220000 {
+ compatible = "mediatek,mt8173-afe-pcm";
+ power-domains = <&scpsys MT8173_POWER_DOMAIN_AUDIO>;
+ };

Subject: [PATCH 08/76] soc: Mediatek: Add SCPSYS power domain driver
This adds a power domain driver for the Mediatek SCPSYS unit.
The System Control Processor System (SCPSYS) has several power
management related tasks in the system. The tasks include thermal
measurement, dynamic voltage frequency scaling (DVFS), interrupt
filter and lowlevel sleep control. The System Power Manager (SPM)
inside the SCPSYS is for the MTCMOS power domain control.
For now this driver only adds power domain support, the more
advanced features are not yet supported. The driver implements
the generic PM domain device tree bindings, the first user will
most likely be the Mediatek AFE audio driver.

Subject: [PATCH 12/76] thermal: remove useless call to
thermal_zone_device_set_polling
When the thermal zone has no get_temp callback then thermal_zone_device_register()
calls thermal_zone_device_set_polling() with a polling delay of 0. This
only cancels the poll_queue. Since the poll_queue hasn't been scheduled this
is a no-op. Remove it.

Subject: [PATCH 16/76] thermal: streamline get_trend callbacks
The .get_trend callback in struct thermal_zone_device_ops has the prototype:
int (*get_trend) (struct thermal_zone_device *, int,
enum thermal_trend *);
whereas the .get_trend callback in struct thermal_zone_of_device_ops has:
int (*get_trend)(void *, long *);
Streamline both prototypes and add the trip argument to the OF callback
aswell and use enum thermal_trend * instead of an integer pointer.
While the OF prototype may be the better one, this should be decided at
framework level and not on OF level.

Subject: [PATCH 17/76] thermal: Allow sensor ops to fail with -ENOSYS
The thermal core uses the existence of the .get_temp, .get_trend and
.set_emul_temp to detect whether this operation exists and should be
used or whether it should be emulated in software. This makes problems
for of-thermal which has to modify the struct thermal_zone_device_ops
during runtime whenever a sensor is registered or unregistered.
Let the core test for -ENOSYS from these callbacks and treat it like
if the callbacks were not present.
This allows of-thermal to always set the sensor related callbacks and
to make struct thermal_zone_device_ops const again.

Now that the thermal core treats -ENOSYS like the callbacks were
not present at all we no longer have to overwrite the ops during
runtime but instead can always set them and return -ENOSYS if no
sensor is registered.

Subject: [PATCH 20/76] thermal: thermal: Add support for hardware-tracked
trip points
This adds support for hardware-tracked trip points to the device tree
thermal sensor framework.
The framework supports an arbitrary number of trip points. Whenever
the current temperature is updated, the trip points immediately
below and above the current temperature are found. A .set_trips
callback is then called with the temperatures. If there is no trip
point above or below the current temperature, the passed trip
temperature will be -INT_MAX or INT_MAX respectively. In this callback,
the driver should program the hardware such that it is notified
when either of these trip points are triggered. When a trip point
is triggered, the driver should call `thermal_zone_device_update'
for the respective thermal zone. This will cause the trip points
to be updated again.
If .set_trips is not implemented, the framework behaves as before.
This patch is based on an earlier version from Mikko Perttunen

+
+This describes the device tree binding for the Mediatek thermal controller
+which measures the on-SoC temperatures. This device does not have its own ADC,
+instead it directly controls the AUXADC via AHB bus accesses. For this reason
+this device needs phandles to the AUXADC.
+
+Required properties:
+- compatible: "mediatek,mt8173-thermal"
+- reg: Address range of the thermal controller
+- interrupts: IRQ for the thermal controller
+- clocks, clock-names: Clocks needed for the thermal controller. required
+ clocks are:
+ "therm": Main clock needed for register access
+ "auxadc": The AUXADC clock
+- resets, reset-names: Reference to the reset controller controlling the thermal
+ controller. Required reset-names:
+ "therm": The main reset line
+- auxadc: A phandle to the AUXADC which the thermal controller uses
+- apmixedsys: A phandle to the APMIXEDSYS controller.
+- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
+
+Example:
+
+ thermal: thermal@1100b000 {
+ #thermal-sensor-cells = <1>;
+ compatible = "mediatek,mt8173-thermal";
+ reg = <0 0x1100b000 0 0x1000>;
+ interrupts = <0 70 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&pericfg CLK_PERI_THERM>, <&pericfg CLK_PERI_AUXADC>;

Subject: [PATCH 23/76] thermal: Add Mediatek thermal controller support
This adds support for the Mediatek thermal controller found on MT8173
and likely other SoCs.
The controller is a bit special. It does not have its own ADC, instead
it controls the on-SoC AUXADC via AHB bus accesses. For this reason
we need the physical address of the AUXADC. Also it controls a mux
using AHB bus accesses, so we need the APMIXEDSYS physical address aswell.

+Mediatek display PWM controller
+
+Required properties:
+ - compatible: should be "mediatek,<name>-disp-pwm"
+ - "mediatek,mt8173-disp-pwm": found on mt8173 SoC
+ - "mediatek,mt6595-disp-pwm": found on mt6595 SoC
+ - reg: physical base address and length of the controller's registers
+ - #pwm-cells: must be 2. See pwm.txt in this directory
+ for a description of the cell format
+ - clocks: phandle and clock specifier of the PWM reference clock
+ - clock-names: must contain the following
+ - "main": clock used to generate PWM signals
+ - "mm": sync signals from the modules of mmsys
+
+Example:
+ pwm0: pwm@1401e000 {
+ compatible = "mediatek,mt8173-disp-pwm",
+ "mediatek,mt6595-disp-pwm";
+ reg = <0 0x1401e000 0 0x1000>;
+ #pwm-cells = <2>;
+ clocks = <&mmsys MM_DISP_PWM026M>,
+ <&mmsys MM_DISP_PWM0MM>;
+ clock-names = "main",
+ "mm";

+* Mediatek's I2C controller
+
+The Mediatek's I2C controller is used to interface with I2C devices.
+
+Required properties:
+ - compatible: value should be either of the following.
+ (a) "mediatek,mt6577-i2c", for i2c compatible with mt6577 i2c.
+ (b) "mediatek,mt6589-i2c", for i2c compatible with mt6589 i2c.
+ (c) "mediatek,mt8127-i2c", for i2c compatible with mt8127 i2c.
+ (d) "mediatek,mt8135-i2c", for i2c compatible with mt8135 i2c.
+ (e) "mediatek,mt8173-i2c", for i2c compatible with mt8173 i2c.
+ - reg: physical base address of the controller and dma base, length of memory
+ mapped region.
+ - interrupts: interrupt number to the cpu.
+ - clock-div: the fixed value for frequency divider of clock source in i2c
+ module. Each IC may be different.
+ - clocks: clock name from clock manager
+ - clock-names: Must include "main" and "dma", if enable have-pmic need include
+ "pmic" extra.
+
+Optional properties:
+ - clock-frequency: Frequency in Hz of the bus when transfer, the default value
+ is 100000.
+ - mediatek,have-pmic: platform can control i2c form special pmic side.
+ Only mt6589 and mt8135 support this feature.
+ - mediatek,use-push-pull: IO config use push-pull mode.
+
+Example:
+
+ i2c0: i2c@1100d000 {
+ compatible = "mediatek,mt6577-i2c";
+ reg = <0x1100d000 0x70>,
+ <0x11000300 0x80>;
+ interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_LOW>;
+ clock-frequency = <400000>;
+ mediatek,have-pmic;
+ clock-div = <16>;
+ clocks = <&i2c0_ck>, <&ap_dma_ck>;
+ clock-names = "main", "dma";
+ };

Subject: [PATCH 31/76] I2C: mediatek: Add driver for MediaTek MT8173 I2C
controller
Add mediatek MT8173 I2C controller driver. Compare to I2C controller
of earlier mediatek SoC, MT8173 fix write-then-read limitation, and
also increase message size to 64kb.

+Mediatek MT8173 cpufreq driver
+-------------------
+
+Mediatek MT8173 cpufreq driver for CPU frequency scaling.
+
+Required properties:
+- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
+- clock-names: Should contain the following:
+ "cpu" - The multiplexer for clock input of CPU cluster.
+ "intermediate" - A parent of "cpu" clock which is used as "intermediate" clock
+ source (usually MAINPLL) when the original CPU PLL is under
+ transition and not stable yet.
+- operating-points: Table of frequencies and voltage CPU could be transitioned into,
+ Frequency should be in KHz units and voltage should be in microvolts.
+- proc-supply: Regulator for Vproc of CPU cluster.
+
+Optional properties:
+- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
+ needs to do "voltage trace" to step by step scale up/down Vproc and
+ Vsram to fit SoC specific needs. When absent, the voltage scaling
+ flow is handled by hardware, hence no software "voltage trace" is
+ needed.
+
+Example:
+--------

+ device_type = "cpu";

+* MTK MMC controller
+
+The MTK MSDC can act as a MMC controller
+to support MMC, SD, and SDIO types of memory cards.
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the msdc driver.
+
+Required properties:
+- compatible: Should be "mediatek,mt8173-mmc","mediatek,mt8135-mmc"
+- interrupts: Should contain MSDC interrupt number
+- clocks: MSDC source clock, HCLK
+- clock-names: "source", "hclk"
+- pinctrl-names: should be "default", "state_uhs"
+- pinctrl-0: should contain default/high speed pin ctrl
+- pinctrl-1: should contain uhs mode pin ctrl
+- vmmc-supply: power to the Core
+- vqmmc-supply: power to the IO
+
+Examples:
+mmc0: mmc@11230000 {
+ compatible = "mediatek,mt8173-mmc", "mediatek,mt8135-mmc";
+ reg = <0 0x11230000 0 0x108>;
+ interrupts = <GIC_SPI 39 IRQ_TYPE_LEVEL_LOW>;
+ vmmc-supply = <&mt6397_vemc_3v3_reg>;
+ vqmmc-supply = <&mt6397_vio18_reg>;
+ clocks = <&pericfg CLK_PERI_MSDC30_0>, <&topckgen CLK_TOP_MSDC50_0_H_SEL>;
+ clock-names = "source", "hclk";
+ pinctrl-names = "default", "state_uhs";
+ pinctrl-0 = <&mmc0_pins_default>;
+ pinctrl-1 = <&mmc0_pins_uhs>;
+};
