Ned Forrester b97c74bddc spi: pxa2xx_spi clock polarity fix
Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select
for a transfer may be asserted before the clock polarity is set on the
interface.  As a result of this bug, the clock signal may have the wrong
polarity at transfer start, so it may need to make an extra half transition
before the intended clock/data signals begin.  (This probably means all
transfers are one bit out of sequence.)

This only occurs on the first transfer following a change in clock polarity
in systems using more than one more than one such polarity.  The fix
assures that the clock mode is properly set before asserting chip select.

This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20.
The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h
for 2.6.25 and newer kernels but this addition must be made in:
include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24,
inclusive

Philipp Zabel 1c44f5f16f gpiolib support for the PXA architecture
This adds gpiolib support for the PXA architecture:
  - move all GPIO API functions from generic.c into gpio.c
  - convert the gpio_get/set_value macros into inline functions

This makes it easier to hook up GPIOs provided by external chips like
ASICs and CPLDs.

Eric Miao 76cb44e1a8 Input: pxa27x_keypad - add debounce_interval to the keypad platform data
Currently, only one debounce_interval is introduced for both direct and
matrix keys. This is true in most cases, although the keypad controller
supports different debounce for direct/matrix keys.

Some platforms do require this to be tuned, instead of the default
reset value of 100ms.

Rotary encoder will always use zero debounce time for now to achieve
certain sensitivity.

Russell King 7b5dea1234 [ARM] pxa: Add PXA3 standby code hooked into the IRQ wake scheme
Wakeup sources on PXA3 are enabled at two levels.  First, the MFP
configuration has to be set to enable which edges a specific pin
will trigger a wakeup.  The pin also has to be routed to a functional
unit.  Lastly, the functional unit must be enabled as a wakeup source
in the appropriate AD*ER registers (AD2D0ER for standby resume.)

This doesn't fit well with the IRQ wake scheme - we currently do a
best effort conversion from IRQ numbers to functional unit wake enable
bits.  For instance, there's several USB client related enable bits but
there's no corresponding IRQs to determine which you'd want.  Conversely,
there's a single enable bit covering several functional units.

eric miao 7f7c8a6192 [ARM] pxa: make MFP configuration processor independent
There are two reasons for making the MFP configuration to be processor
independent, i.e. removing the relationship of configuration bits with
actual MFPR register settings:

   1. power management sometimes requires the MFP to be configured
      differently when in run mode or in low power mode

   2. for future integration of pxa{25x,27x} GPIO configurations

The modifications include:

1. introducing of processor independent MFP configuration bits, as
   defined in [include/asm-arm/arch-pxa/mfp.h]:

	bit  0.. 9 - MFP Pin Number (1024 Pins Maximum)
	bit 10..12 - Alternate Function Selection
	bit 13..15 - Drive Strength
	bit 16..18 - Low Power Mode State
	bit 19..20 - Low Power Mode Edge Detection
	bit 21..22 - Run Mode Pull State
	and so on,

2. moving the processor dependent code from mfp.h into mfp-pxa3xx.h

3. cleaning up of the MFPR bit definitions

4. mapping of processor independent MFP configuration into processor
   specific MFPR register settings is now totally encapsulated within
   pxa3xx_mfp_config()

5. using of "unsigned long" instead of invented type of "mfp_cfg_t"
   according to Documentation/CodingStyle Chapter 5, usage of this
   in platform code will be slowly removed in later patches

Russell King 198a6d5a61 [ARM] pxa: silence warnings from cpu_is_xxx() macros
If only a single CPU type is selected, __cpu_is_xxx() doesn't
use its argument.  This causes the compiler to issue a warning
about an unused variable in the parent function.

Michael Brunner 03d14a5536 [ARM] 4690/1: PXA: fix CKEN corruption in PXA27x AC97 cold reset code
Fix CKEN register corruption in the PXA27x cold reset code
located in sound/arm/pxa27x-ac97.c. The problem has been
introduced with a pxa_set_cken() function change in linux 2.6.23.
This patch is based on patch 4527/1 that fixes the same problem in
the ASoC PXA-AC97 driver. Additionally a definition for the CKEN
index value is added and applied to both PXA AC97 drivers.

Rafael J. Wysocki 95d9ffbe01 PM: Move definition of struct pm_ops to suspend.h
Move the definition of 'struct pm_ops' and related functions from <linux/pm.h>
to <linux/suspend.h> .

There are, at least, the following reasons to do that:
* 'struct pm_ops' is specifically related to suspend and not to the power
  management in general.
* As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it
  causes the entire kernel to be recompiled, which is unnecessary and annoying.
* Some suspend-related features are already defined in <linux/suspend.h>, so it
  is logical to move the definition of 'struct pm_ops' into there.
* 'struct hibernation_ops', being the hibernation-related counterpart of
  'struct pm_ops', is defined in <linux/suspend.h> .

Hans J. Koch 9ffa739606 pxafb: Add support for other palette formats
This patch adds support for the other three palette formats possible with
the PXA LCD controller. This is required on boards where an LCD is connected
with all its 18 bits. With this patch, it's possible to use an 8-bit mode
with 18-bit palette entries. This used to be possible in 2.4 kernels but
disappeared in 2.6. With current kernels, you can only get wrong colours
out of an LCD connected this way.

Users can choose the palette format by doing something like this
in their board definition:

static struct pxafb_mach_info my_fb_info = {
        [...]
        .lccr3          = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3,
        .lccr4          = LCCR4_PAL_FOR_2,
        [...]
};
