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.

The AT91 I2C driver is currently marked as "broken" due to hardware
issues.  This patch enables AT91-based platforms to also use the
bitbanged GPIO for I2C.

This updates platform setup logic (setting up an i2c-gpio device
using the same pins as the i2c-at91 device, unless only the BROKEN
driver is enabled).

Also make use of the new-style initialization of I2C devices using
i2c_register_board_info().

Kevin Hilman a8fa9ba623 [ARM] 4644/2: fix flush_kern_tlb_range() in module space
For kernel addresses between TASK_SIZE and PAGE_OFFSET,
flush_tlb_kern_range() does not work as would be expected.

The TLB invalidate works with a matching ASID, or on entries marked as
global.  The set_pte_at() macro marks addresses >= PAGE_OFFSET as
global, but not addresses from TASK_SIZE to PAGE_OFFSET, which are
also kernel addresses.

The result is that the entries in this range are not actually
invalidated by flush_tlb_kern_range().

This patch instead marks addresses >= TASK_SIZE as global.

Jens Axboe 18dabf473e Change table chaining layout
Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:

- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
  at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
  with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
  NULL when passed such an entry.

It's thus important that sg table users use the proper accessors to get
and set the page member.

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> .

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.

GCC can be made to warn about usage of long long types with ISO C90
(-ansi), but only with -pedantic.  You can write this in a way that even
then it doesn't cause warnings, namely by:

#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;
#endif

The __extension__ keyword in front of this switches off any pedantic
warnings for this expression.

Pavel Pisa 9da505d1f9 imxfb: fast read flag and nonstandard field configurable
The i.MX frame-buffer read operation should be faster for all configurations
then drawing each individual character again in response to scroll events.

The nonstandard fields allows to configure frame-buffer special options flags
for different display configurations by board specific initialization code.

One of such specific options is reversed order of pixels in each individual
byte.  i.MX frame-buffer seems to be designed for big-endian use first.  The
byte order is correctly configured for little-endian ordering, but if 1, 2 or
4 bits per pixel are used, pixels ordering is incompatible to Linux generic
frame-buffer drawing functions.

The patch "Allow generic BitBLT functions to work with swapped pixel order in
bytes" introduces required functionality into FBDEV core.  The pixels ordering
selection has to be enabled at compile time CONFIG_FB_CFB_REV_PIXELS_IN_BYTE
and for each display configuration which requires it by flag
FB_NONSTD_REV_PIX_IN_B in "nonstd" field of info structure.

This patch provides way for board specific code to select this option.

Krzysztof Helt 36f31a7084 s3c2410fb: removes lcdcon1 register value from s3c2410fb_display
This patch removes lcdcon1 register field from the s3c2410fb_display as all
bits are calculated from other fields.

Krzysztof Helt 69816699fa s3c2410fb: adds pixclock to s3c2410fb_display
This patch adds pixelclock field to the s3c2410fb_display structure and make
use of it in the driver.

The Bast machine defined 9 modes but pixclock and margin values are defined
only for the 640x480 modes so I removed other modes.

This patch also fixes wrong display type constant for the SMDK2440 board.

This patch adds margins fields to the s3c2410fb_display
structure. It also sets display type and horizontal
margins in all platform files that use the s3c2410fb

Krzysztof Helt 09fe75f6f9 s3c2410fb: multi-display support
This patch adds a new structure to describe and handle
more than one panel (display mode) for the s3c2410 framebuffer.
This structure is added after the pxafb driver.

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,
        [...]
};

Russell King 3e0cc7ee04 [ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()
pxa_gpio_mode() is a universal call that fiddles with the GAFR
(gpio alternate function register.)  GAFR does not exist on PXA3
CPUs, but instead the alternate functions are controlled via the
MFP support code.

Platforms are expected to configure the MFP according to their
needs in their platform support code rather than drivers.  We
extend this idea to the GAFR, and make the gpio_direction_*()
functions purely operate on the GPIO level.

This means platform support code is entirely responsible for
configuring the GPIOs alternate functions on all PXA CPU types.
