Subject: [PATCH 02/35] MIPS: ath79: separate common PCI code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
are common functions and only instance one of them
can be present in a single kernel.
Currently these functions can be built only if the
CONFIG_SOC_AR724X option is selected. However the
ath79 platform contain support for the AR71XX SoCs,.
The AR71XX SoCs have a differnet PCI controller,
and those will require a different code.
Move the common PCI code into a separeate file in
order to be able to use that with other SoCs as
well.

Subject: [PATCH 03/35] MIPS: ath79: rename pci-ath724x.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The declared function in this header file is used by the
ath79 platform code only. Move the header to the platform
directory.
Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
Acked-by: René Bolldorf <xsecute@googlemail.com>
v4: - add an Acked-by tag from René
v3: - move include "pci.h" out of the #ifdef CONFIG_PCI section
v2: - no changes

From fbf38a9b03d0c47ed602f090ebb2d8ecc0d51d04 Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Fri, 18 Nov 2011 10:25:26 +0100
Subject: [PATCH 05/35] MIPS: ath79: add a common PCI registration function
The current code unconditionally registers the AR724X
specific PCI controller, even if the kernel is running
on a different SoC.
Add a common function for PCI controller registration,
and only register the AR724X PCI controller if the kernel
is running on an AR724X SoC.
Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
v4: - simplify ath79_register_pci function
v3: - fix compile error if CONFIG_PCI is not defined
- add __init annotation to ath79_register_pci
v2: - no changes

Subject: [PATCH 07/35] MIPS: ath79: replace ath724x to ar724x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Replace the 'ath724x' to 'ar724x' in function, variable and
structure names to reflect the name of the real SoC.

Subject: [PATCH 10/35] MIPS: ath79: fix broken ar724x_pci_{read,write} functions
The current ar724x_pci_{read,write} functions are
broken. Due to that, pci_read_config_byte returns
with bogus values, and pci_write_config_{byte,word}
unconditionally clears the accessed PCI configuration
registers instead of changing the value of them.
The patch fixes the broken functions, thus the PCI
configuration space can be accessed correctly.

Subject: [PATCH 11/35] MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCs
The PCI controller of the AR724X SoCs has a hardware
bag. If the BAR0 register of the PCI device is set to
the proper base address, the memory address space of
the device is not accessible.
When the device driver tries to access the memory
address space of the PCI device, it leads to data
bus error, similiar to this:
Data bus error, epc == 801f69a0, ra == 801f698c

From cfb725275ea25857e8f0e3bf358fff7c84cc787c Mon Sep 17 00:00:00 2001
From: Gabor Juhos <juhosg@openwrt.org>
Date: Tue, 22 Nov 2011 13:59:39 +0100
Subject: [PATCH 12/35] MIPS: ath79: fix a wrong IRQ number
The Ubiquiti XM board setup code uses an invalid
IRQ number, because it if above of NR_IRQS. This
leads to failed 'request_irq' calls:
ath9k 0000:00:00.0: request_irq failed
ath9k: probe of 0000:00:00.0 failed with error -22
Preserve some IRQ numbers for the built-in IRQ
controller of PCI host controllers in the
AR71XX/AR724X SoCs, and use the correct IRQ
number in the board setup code.
Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
v2: - no changes
The IRQ controller code is also missing, that will be
added in a separate patch.

Subject: [PATCH 13/35] MIPS: ath79: add PCI IRQ handling code for AR724X SoCs
The PCI Host Controller of the AR724x SoC has a
built-in IRQ controller. The current code does
not supports that, so the IRQ lines wired to this
controller are not usable. This leads to failed
'request_irq' calls:
ath9k 0000:00:00.0: request_irq failed
ath9k: probe of 0000:00:00.0 failed with error -89
This patch adds support for the IRQ controller
in order to make PCI IRQs work.

Subject: [PATCH 14/35] MIPS: ath79: get rid of some ifdefs in mach-ubnt-xm.c
Remove a superfluous ifdef around an include. Also
reorganize the board setup code a bit, so another
ifdef can be removed.

This can be avoided by calling the 'ar724x_pci_add_data'
function from the board specific setup code. However it
makes no sense to use that function for every board,
especially when the board does not needs to set the
platform_data field of any PCI device.
The patch allows the board setup code to specify a board
specific function if that is required.

v2: - no changes
The pci_irq_map function can throw another NULL pointer
dereference, that will be fixed in a subsequent patch.

Subject: [PATCH 16/35] MIPS: ath79: add support for the PCI host controller of the AR71XX SoCs
The Atheros AR71XX SoCs have a built-in PCI Host Controller.
This patch adds a driver for that, and modifies the relevant
files in order to allow to register the PCI controller from
board specific setup.

From 8a1a5852aa7f8cfc027b2b0bb51cbbac4309e144 Mon Sep 17 00:00:00 2001

Subject: [PATCH 17/35] MIPS: ath79: allow to use SoC specific PCI IRQ maps
The PCI controllers in the AR71XX and in the
AR724X SoCs are different, and both of them
uses different IRQ wiring.
The patch modifies the 'pcibios_map_irq' function
in order to allow to use different IRQ maps for
the different SoCs. The patch also adds a function,
which lets the board setup code to override the
default IRQ map.

Just in case if someone is curious about why 2008 and 2009 years are
present in this change:
The recent PCI specific changes were based on an existing
code which can be found in the OpenWrt repository, and we
are working on that since 2008.

Date: Sun, 11 Dec 2011 17:36:42 +0100
Subject: [PATCH 23/35] MIPS: ath79: add SoC detection code for AR934X
Also add 'soc_is_ar934[124x]' helper functions and a Kconfig
symbol for the AR934X SoCs.

Subject: [PATCH 26/35] MIPS: ath79: rework IP2/IP3 interrupt handling
The current implementation assumes that flushing the
DDR writeback buffer is required for IP2/IP3 interrupts,
however this is not true for all SoCs.
Use SoC specific IP2/IP3 handlers instead of flushing
the buffers in the dispatcher code.

Subject: [PATCH 32/35] MIPS: ath79: add PCI_AR724X Kconfig symbol
The AR724X specific PCI code can be used for the
AR934X SoCs, however it can be selected only if
SOC_AR724X is set.
Introduce a new Kconfig symbol in order to be able
to use the code for AR934X as well.

Subject: [PATCH 1/7] spi/ath79: add delay between SCK changes
The driver uses the "as fast as it can" approach
to drive the SCK signal. However this does not
work with certain low speed SPI chips (e.g. the
PCF2123 RTC chip). Add per-bit slowdowns in order
to be able to use the driver with such chips as
well.

Subject: [PATCH 3/7] spi/ath79: remove superfluous chip select code
The spi_bitbang driver calls the chipselect function
of the driver from spi_bitbang_setup in order to
deselect the given SPI chip, so we don't have to
initialize the CS line here.
