66c1ca0190 fbmem: fix fb_info->lock and mm->mmap_sem circular locking dependency
Fix a circular locking dependency in the frame buffer console driver
pushing down the mutex fb_info->lock.

Circular locking dependecies occur calling the blocking
fb_notifier_call_chain() with fb_info->lock held.  Notifier callbacks can
try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the
reverse order mm->mmap_sem => fb_info->lock.

- The Laguna GD5465 (AGP) has one register more than non-AGP chips.
  Recognize the AGP version and write a tile control register only on the
  AGP version.  Tested only on an AGP card.

- Bump up RAMDAC frequencies after X11 code.  This allow to drive a flat
  panel resolution 1680x1050 at 16bpp from the 4MB card.

- Fix screen start address overflow bits on Laguna cards (CRT1D
  register).

- Fix exit path in the cirrusfb_pci_register() in case of error.

99a4584752 cirrusfb: check_var improvements
Break cirrusfb_decode_var() function into two parts:
cirrusfb_check_pixclock() which can be called from the
cirrusfb_check_var() aand merge rest into the cirrusfb_set_par_foo().
This allows rejecting modes with too high pixclock before before any
change to hardware state (and a console is messed up).

Also, fix RGB field's lengths for 8bpp modes to correct ones so X11 works
with fbdev driver with cirrusfb.

Kill some redundant function calls or register loads.

48c329e906 cirrusfb: various improvements
Various improvements to the code:
- kill a structure with only one
  field: multiplexing and use the
  field directly
- move the cirrusfb_ops structure
  down the file to kill forward
  declarations
- move cirrusfb_init() to kill
  forward declaration
- kill register loads done already
  in the init_vgachip()
- kill assigments done by higher
  layer in the cirrusfb_pan_display()
- do not overwrite line pitch bit in
  the CL_CRT1D register
- kill btype variables if they were
  used only once or twice
- add cpu_relax() in the busy waiting
  loop

The fix to the CL_CRT1D register handling makess the 1024x768 32bpp mode
work.  Previously, only lower resolution modes have worked with 32bpp.

6e30fc086d cirrusfb: add mmio registers for Laguna chipsets
The Laguna chipsets use special registers which are available through the
mmio area.  The cirrusfb driver does not use memory mapped registers for
the PCI cards.

Add the memory mapped area for Laguna chipsets and add basic usage of the
special Laguna registers after SVGALIB code.

This gives readable console at 16bpp on the GD-5465 (Laguna AGP).  The
8bpp and 32bpp depths are still broken.

78d89ef40c rtc: convert LEAP_YEAR into an inline
- the LEAP_YEAR macro is buggy - it references its arg multiple times.
  Fix this by turning it into a C function.

- give it a more approriate name

- Move it to rtc.h so that other .c files can use it, instead of copying it.

3f1c6ebf57 powerpc: add mmc-spi-slot bindings
The bindings describes a case where MMC/SD/SDIO slot directly connected to
a SPI bus.  Such setups are widely used on embedded PowerPC boards.

The patch also adds the mmc-spi-slot entry to the OpenFirmware modalias
table.

35b4b3c0c1 spi_mpc83xx: add OF platform driver bindings
Implement full support for OF SPI bindings.  Now the driver can manage its
own chip selects without any help from the board files and/or fsl_soc
constructors.

The "legacy" code is well isolated and could be removed as time goes by.

364fdbc00f spi_mpc83xx: rework chip selects handling
The main purpose of this patch is to pass 'struct spi_device' to the chip
select handling routines.  This is needed so that we could implement
full-fledged OpenFirmware support for this driver.

While at it, also:
- Replace two {de,activate}_cs routines by single cs_contol().
- Don't duplicate platform data callbacks in mpc83xx_spi struct.

This solves the dependency between lis3lv02d.[ch] and ACPI specific

casted to 'struct acpi_device' in the ACIP layer.  Changed hp_accel.c
accordingly.
