Subject: [ARM] SMDK6410: Ensure LCD settings are setup

Ensure that the LCD output type is RGB and that
the modem interface is not bypassing the LCD
block. This ensures the LCD interface output
gets to the pins in the correct format.

Subject: [ARM] SMDK6410: Support WM1190-EV1 PMIC board

The SMDK6410 supports pluggable PMIC boards. One such board is the
Wolfson Microelectronics 1190-EV1 for the WM8350 PMICs. This patch
introduces initial support for this module. Further patches will
add additional integration with the system as support for the
S3C6410 and other devices on the system improves.

Using an active high IRQ ensures that the WM8350 interrupt handling

and R21 fitted to connect EINT12 to the PMIC module rather thant the
fixed regulators on the CPU module.

Subject: [ARM] SMDK6410: Mark all supplies as always_on

Since no consumers are currently configured for the SMDK6410 mark all
the supplies on the board as being always_on, ensuring interoperability
with future regulator API changes to disable unused regulators.

Subject: [PATCH] S3C64XX: Basic A&W6410 board support patch V2

A&W6410 board uses Samsung S3C6410 SoC and it is registered with 2183.
Framebuffer and ethernet devices are supported currently.

Unnecessary header file is removed.
Fix to use __raw_writel() and __raw_readl() for accessing mapped address.

Thank you for your comments.

Subject: [ARM] S3C24XX: Remove hardware specific registers from DMA calls

The S3C24XX DMA API channel configuration registers are being passed
values comprised of register values which makes it hard to move the
API to cover both the S3C24XX and S3C64XX.

These values can be calculated from knowing which device the channel
is connected to, so remove them from the two calls s3c2410_dma_config
and s3c2410_dma_devconfig.

Subject: [ARM] S3C24XX: DMA: Split hardware regs out of <mach/dma.h>

The <mach/dma.h> is for the driver API for the DMA system and should
not have anything relying on the CPU specific registers.

Remove the registers to <plat/dma-regs.h> for the code that really
needs to know about them.

Subject: [ARM] S3C24XX: dma.h should not include <mach/hardware.h>

The dma.h header does not need to include <mach/hardware.h> as there
is nothing it depends on. Remove the include and fixup the couple of
places where <mach/map.h> was not explicitly included (dragged in
via <mach/hardware.h>)

Note, we have to fix arch/arm/plat-s3c24xx/pm.c which seems to rely
on having <mach/hardware.h> included by this method.

Add an s3c64xx_sysclass and device for items that currently
want to bind to any s3c64xx processor. The first user of this

Subject: [ARM] S3C64XX: Add IRQ PM code

Add support for saving the state of the IRQ registers over suspend.

This requires moving the S3C64XX UART registers into <plat/regs-serial.h>
and adding irq-pm.c which saves the state of all the IRQ registers.

The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and
IRQ_EINT_GROUP registers as it was easier than adding three different
files. Also ensuring that all the registers are restored to the same
state as before suspend is considered to be the best thing to do.

Note, we do not suspend the VIC here, this is done by the VIC driver
itself.

Subject: [ARM] S3C: GPIO PM core GPIOlib integration

Move the GPIO suspend/resume support inline with the gpiolib support
so that it will work with both the S3C24XX and S3C64XX series.

The s3c_gpio_chip is extended to have a pm callback and a save block
to keep the state of the GPIO over suspend, and the code from the
s3c24xx implementation is added to a new common file.

The suspend process now uses the list of registered chips to go through
saving and restoring each one as appropriate, using the pm callback to
select the appropriate routine depending on the type of control register
present.

This change also means that any additional GPIO added should not require
changes to the PM.

Subject: [ARM] VIC: Add power management device

Add power management support to the VIC by registering
each VIC as a system device to get suspend/resume
events going.

Since the VIC registeration is done early, we need to
record the VICs in a static array which is used to add
the system devices later once the initcalls are run. This
means there is now a configuration value for the number
of VICs in the system.

Subject: [ARM] S3C: ADC: Expose number of remaining conversions to convert
 callback

This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.

This change is simple enough to be compatible with existing
code that can just define the new pointer in the callback
and ignore it.

Sample usage:

Subject: [ARM] S3C24XX: GPIO: Remove s3c2410_gpio_irq2pin() call

Remove the s3c2410_gpio_irq2pin() function as it is not being
used in any in kernel driver and the function is probably not
being used anywhere else.

This is also part of the effort to remove any of the s3c24xx gpio
specific code that cannot be recreated by using the gpiolib
framework now in the kernel.

Subject: [ARM] S3C24XX: GPIO: Remove pin specific input and output defines

The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.

The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.

Do the following replacements:

   S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
   S3C2410_GP[A-Z][0-9]*_\INP  => /S3C2410_GPIO_INPUT
   S3C2410_GPA[0-9]*_OUT       => S3C2410_GPIO_OUTPUT

to remove any usages of these and prepare the header for
the removal of these.

The following command was used to acheive this:

find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g'

Subject: [ARM] S3C: Move watchdog system reset to own file.

Move the watchdog reset code from <mach/system-reset.h> to
a new file <plat/watchdog-reset.h> as this code is needed
by both s3c2410, s3c64xx and soon-to-be added s3c24a0.

From ec976d6eb021dc8f2994248c310a41540f4756bd Mon Sep 17 00:00:00 2001
From: Ben Dooks <ben-linux@fluff.org>
Date: Wed, 13 May 2009 22:52:24 +0100
Subject: [ARM] S3C24XX: GPIO: Move gpio functions out of <mach/hardware.h>

Move all the gpio functions out of <mach/hardware.h> as
this file is for defining the generic IO base addresses
for the kernel IO calls.

Make a new header <mach/gpio-fns.h> to take this and
include it via the chain from <linux/gpio.h> which is
what most of these files should be using (and will be
changed as soon as possible).

Note, this does make minor changes to some drivers but
should not mess up any pending merges.

Subject: [ARM] S3C24XX: Fix missing <linux/sysdev.h>

In our recent changes, arch/arm/plat-s3c24xx/gpiolib.c needs
to have <linux/sysdev.h> included for it to build.

This fixes the following error/warnings:

arch/arm/plat-s3c/include/plat/pm.h:104: error: expected declaration specifiers or '...' before 'pm_message_t'
arch/arm/plat-s3c/include/plat/pm.h:104: warning: 'struct sys_device' declared inside parameter list
arch/arm/plat-s3c/include/plat/pm.h:104: warning: its scope is only this definition or declaration, which is probably not what you want
arch/arm/plat-s3c/include/plat/pm.h:105: warning: 'struct sys_device' declared inside parameter list

Subject: [ARM] S3C24XX: GPIO: Clean out unused definitions in
 <mach/regs-gpio.h>

The <mach/regs-gpio.h> really does not need the input and output
pin configurations as these are standard and have a generic
representation (plus the s3c24xx gpio specific code is going to
be phased out soon).

The following sed was applied to remove the lines:

    sed -i~ -e '/S3C2410_GP[A-Z][0-9]*_\INP/d' \
	    -e '/S3C2410_GP[A-Z][0-9]*_\OUTP/d' \
	    -e '/S3C2410_GPA[0-9]*_OUT/d'

to remove these.

Subject: [ARM] S3C24XX: GPIO: Start removal of S3C24XX_GPIO_BASE

The S3C24XX_GPIO_BASE makes it difficult to compress the
GPIO number space, and is only used in a few places of
which everything outside arch/arm/plat-s3c24xx/gpiolib.c
will be removed as soon as possible.

Change gpiolib.c to use the S3C2410_GPxCON register addresses
as the base for each bank, thus eliminating S3C24XX_GPIO_BASE.

Subject: [ARM] S3C24XX: GPIO: Add S3C64XX style GPIO numbering

Move the new style of GPIO numbering by using a single
macro for each GPIO bank. This means S3C2410_GPA0 becomes
S3C2410_GPA(0), and so on.

Subject: [ARM] S3C24XX: GPIO: Change to macros for GPIO numbering

Prepare to remove the large number of S3C2410_GPxn defines
by moving to S3C2410_GPx(n) in arch/arm.

The following perl was used to change the files:

    perl -pi~ -e 's/S3C2410_GP([A-Z])([0-9]+)([^_^0-9])/S3C2410_GP\1\(\2\)\3/g'

From fa7a7883fe5c647decee57a9c1b86a96408c5b26 Mon Sep 17 00:00:00 2001
From: Ben Dooks <ben@simtec.co.uk>
Date: Tue, 10 Mar 2009 23:57:26 +0000
Subject: [ARM] S3C64XX: DMA support

Add support for the DMA blocks in the S3C64XX series of CPUS,
which are based on the ARM PL080 PrimeCell system.

Unfortunately, these DMA controllers diverge from the PL080
design by adding another DMA controller register and
configuration for OneNAND.

Subject: [ARM] S3C24XX: GPIO: Move gpiolib initialisation earlier

The arch_initcall() is too late for board initialisation to use
gpiolib when doing their machine specific initilisation via the
.init_machine callback.

Bring the file into line with the s3c64xx implementation and use
the core_initcall() to register the GPIO chips.
