ad68bb9f7a ARM: pxa: Access SMEMC via virtual addresses
This is important because on PXA3xx, the physical mapping of SMEMC registers
differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx
and PXA320, the PCMCIA driver was adjusted accordingly as well.

Also, various places in the kernel had to be patched to use
__raw_read/__raw_write.

851982c1b6 ARM: pxa: Introduce pxa{25x,27x,3xx}_map_io()
This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish
between PXA25x/PXA27x and PXA3xx memory mapping.

Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io()
and pxa3xx_map_io() is included.

799929d704 ARM: pxa: reduce the scope of get_memclk_frequency_10khz()
Up to now, only pxa2xx pcmcia driver is using the API. No other device driver
is using this API in PXA3xx or any other PXA silicons.

Restrict the scope only on pxa2xx and remove the implementation of pxa3xx. So
we can avoid oo much checking on cpuid after more pxa chips supported.

f0fba2ad1b ASoC: multi-component - ASoC Multi-Component Support
This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.

 struct snd_soc_codec    --->  struct snd_soc_codec (device data)
                          +->  struct snd_soc_codec_driver (driver data)

 struct snd_soc_platform --->  struct snd_soc_platform (device data)
                          +->  struct snd_soc_platform_driver (driver data)

 struct snd_soc_dai      --->  struct snd_soc_dai (device data)
                          +->  struct snd_soc_dai_driver (driver data)

 struct snd_soc_device   --->  deleted

This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.

The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.

This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.

Other notable multi-component changes:-

 * Stream operations now de-reference less structures.
 * close_delayed work() now runs on a DAI basis rather than looping all DAIs
   in a card.
 * PM suspend()/resume() operations can now handle N CODECs and Platforms
   per sound card.
 * Added soc_bind_dai_link() to bind the component devices to the sound card.
 * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
   DAI link components.
 * sysfs entries can now be registered per component per card.
 * snd_soc_new_pcms() functionailty rolled into dai_link_probe().
 * snd_soc_register_codec() now does all the codec list and mutex init.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

 o Make CODEC driver a platform driver
 o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
 o Removed all static codec pointers (drivers now support > 1 codec dev)
 o snd_soc_register_pcms() now done by core.
 o snd_soc_register_dai() folded into snd_soc_register_codec().

cc155c6f2c [ARM] pxa: allow platforms to control which uarts are registered
For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.

In addition, a while back there was a request to be able to pass
platform data to the UART driver.

This patch enables all of this by providing functions platforms can
call to register each individual UART.

284d115ec9 [ARM] pxa: separate PXA25x and PXA27x UDC register definitions
The PXA25x and PXA27x USB device controller register definitions are
different.  Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.

This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.

Remove these definitions from pxa-regs.h, and place them in separate
files.  Include these files where appropriate.

Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

4be35e236c [ARM] pxa: move mfp sysdev registeration out for suspend/resume order
MFP configurations after resume should be done before the GPIO registers
are restored.  Move the mfp sysdev registeration to the same place where
GPIO and IRQ sysdev(s) are registered to better control the order.

b9e25aced3 [ARM] pxa: merge assignment of set_wake into pxa_init_{irq,gpio}()
To further clean up the GPIO and IRQ structure:

1. pxa_init_irq_gpio() and pxa_init_gpio() combines into a single
   function pxa_init_gpio()

2. assignment of set_wake merged into pxa_init_{irq,gpio}() as
   an argument

f6fb7af476 [ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into one
This makes the code better organized and simplified a bit.  The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.

This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable.  The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)

The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0).

"struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.

86260f9873 [ARM] 4824/1: pxa: clear RDH bit after any reset
According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"c4d1fb627ff3072", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.

We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.
