From 884d3962ef4787c8cf0b8a7a673531c623d1dff8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 334/752] video: da8xx-fb: adding dt support
Enhancing driver to enable probe triggered by a corresponding dt entry.
Add da8xx-fb.txt documentation to devicetree section.
Obtain fb_videomode details for the connected lcd panel using the
display timing details present in DT.
Ensure that platform data is present before checking whether platform
callback is present (the one used to control backlight). So far this
was not an issue as driver was purely non-DT triggered, but now DT
support has been added this check must be performed.
v2: squashing multiple commits from Afzal Mohammed (afzal@ti.com)
v3: remove superfluous cast
v4: expose both ti,am3352-lcdc and ti,da830-lcdc for .compatible
as driver can use enhanced features of all version of the
silicon block.
v5: addressed review comments from Prabhakar Lad
v6: Changed the .compatible naming to match the existing drm bindings
for am33xx devices
v7: clarify which compatible to use in the documentation for DA850

+TI LCD Controller on DA830/DA850/AM335x SoC's
+
+Required properties:
+- compatible:
+ DA830, DA850 - "ti,da8xx-tilcdc"
+ AM335x SoC's - "ti,am33xx-tilcdc"
+- reg: Address range of lcdc register set
+- interrupts: lcdc interrupt
+- display-timings: typical videomode of lcd panel, represented as child.
+ Refer Documentation/devicetree/bindings/video/display-timing.txt for
+ display timing binding details. If multiple videomodes are mentioned
+ in display timings node, typical videomode has to be mentioned as the
+ native mode or it has to be first child (driver cares only for native
+ videomode).
+
+Recommended properties:
+- ti,hwmods: Name of the hwmod associated to the LCDC
+
+Example for am335x SoC's:
+
+lcdc@4830e000 {
+ compatible = "ti,am33xx-tilcdc";
+ reg = <0x4830e000 0x1000>;
+ interrupts = <36>;

From: Darren Etheridge <detheridge@ti.com>
Date: Mon, 4 Nov 2013 12:27:40 -0600
Subject: [PATCH 752/752] video/da8xx-fb fix defect with vsync callback
invocation
Fix defect where SGX is running at half of the expected framerate.
The original patch (@ commit ID 9a1a810516ae9cb3259b898b6879901c5b44fa90)
seems to have a mistake where it only calls the callback
for the even or the odd frames depending on the revision of the LCD controller
This patch corrects this and invokes the callback for both odd and even frame
for just the Rev02 version of the LCDC (won't find an SGX GPU on a Rev01).

For modules/IPs/hwmods which do not have
-1- sys->class->reset()
and
-2- hardreset lines
and
-3- No way to do an ocp reset (no sysc control)
the flag 'HWMOD_INIT_NO_RESET' is not much useful.
Cleanup all such instances across various hwmod data files.

On OMAP we have co-processor IPs, memory controllers,
GPIOs which control regulators and power switches to
PMIC, and SoC internal Bus IPs, some or most of which
should either not be reset or idled or both at init.
(In some cases there are erratas which prevent an IP
from being reset)
Have a way to pass this information from DT.
Update the am33xx/omap4 and omap5 dtsi files with the
new bindings for modules which either should not be
idled. reset or both. A later patch would cleanup the
same information that exists today as part of the hwmod
data files.

With DT bindings to specify which devices should not be idled and reset
at init being in place, and the corresponding dtsi files for am33xx/omap4
and omap5 updated using those bindings, we can now clean up hwmod internal
flags for HWMOD_INIT_NO_RESET and HWMOD_INIT_NO_IDLE which were infact used
to specify the exact same information.
For GPMC, the HWMOD_INIT_NO_RESET flag seems to be added in hwmod not due to
any errata around the GPMC IP, but rather because any timings
set by the bootloader are not being correctly programmed by the kernel.
This seems like something that needs to be fixed as part of GPMC driver
in the kernel, and hence the flag is left as is in hwmod, which can be
removed once the driver does what its expected to.

Subject: [PATCH 212/752] ASoC: davinci-evm: Add device tree binding
Device tree support for Davinci Machine driver
When the board boots with device tree, the driver will receive card,
codec, dai interface details (like the card name, DAPM routing map,
phandle for the audio components described in the dts file, codec mclk
speed). The card will be set up based on this information. Since the
routing is provided via DT we can mark the card fully routed so core
can take care of disconnecting the unused pins.

Subject: [PATCH 213/752] ASoC: davinci-mcasp: Add DMA register locations to
DT
This patch adds DMA register location to mcasp DT bindings. On am33xx
SoCs the McASP registers are mapped trough L4 interconnect, which is
not accessible by the DMA controller, so McASP data port is mapped
trough L3 to a different location.

Extract DMA channels directly from DT as they can not be found from
platform resources anymore. This is a work-around until davinci audio
driver is updated to use dmaengine.

Change the name of the sound card to 'AM335x-EVM' from 'DA830 EVM'.
User space might need to differentiate between the boards when it comes to
audio setup (mixer config, PCM lookup, etc).
It is better to use unique name for different boards.

Subject: [PATCH 226/752] ASoC: davinci: mcasp: Remove redundant
num-serializer DT parameter
The serial-dir array gives this information so there is no need to have the
num-serializer property in DT description.
Just ignore the property in the driver the DTS files can be updated
separately without regression.
Update the documentation at the same time for davinci-mcasp

Subject: ARM: dts: omap4-panda-es: Do not reset gpio1
Do not reset GPIO1 at boot-up because GPIO 7 in GPIO1 block is used on
OMAP4460 PandaBoard-ES to select voltage register in TPS62361 which
supplies VDD_MPU.
Without this, OMAP4460 PandaBoard-ES boards fail to boot-up because
MPU voltage switches over to VSET0 voltage value (boot voltage) which
is not sufficient to operate the device at OPP100.

Subject: ARM: OMAP3+: do not register non-dt OPP tables for device tree boot
OMAP3+ supports both device tree and non-device tree boot.
Device tree bindings for OMAP3+ is supposed to be added via dts following:
Documentation/devicetree/bindings/power/opp.txt
Since we now have device tree entries for OMAP3+ cpu OPPs,
The current code wrongly adds duplicate OPPs. So, dont register OPPs
when booting using device tree.

Subject: ARM: OMAP2+: add missing lateinit hook for calling pm late init
AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce
SoC specific hook with a call to OMAP2+ generic lateinit hook. This
allows the generic late initializations such as cpufreq hooks to be
active.
Based on out-of-tree patches that need to be introduced in
mainline, this introduction allows us to provide the foundation for
further SoC specific features as they are developed.
