Patch 5879/1: ep93xx: define magic numbers for pll1 and pll2 broke
the ep93xx build due to one missing rename of EP93XX_SYSCON_CLOCK_SET2.
The correct name should be EP93XX_SYSCON_CLKSET2.

Currently <asm/mach/irq.h> is included by core.c. This header
includes <linux/irq.h> and defines a number of internal functions.
These internal functions are not needed by this file. Change the

This reorganizes the vic.c code in anticipation of a second patch
to use struct vic_device as the data stored in set_irq_chip_data().

The code now has the following flow:

1) struct vic_device definition, static variables, and to_vic()
   moved to the start of the code.
2) common code (vic_init2)
3) vic power management callbacks
4) vic power management initialization/registration
5) irq_chip callbacks
6) vendor specific vic initialization
7) vic initialization

In addition the typo vik_init_st is fixed (vic_init_st).

There is no functional change with this patch.

On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.

The PMNC_D bit should not be set, this patch fixes it.

This avoids races in the VFP code where the dead thread may have
state on another CPU.  By moving this code to exit_thread(), we
will be running as the thread, and therefore be running on the
current CPU.

This means that we can ensure that the only local state is accessed
in the thread notifiers.

Add pseudo-DMA by FIQ to the S3C24XX SPI driver.  This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.

Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch).  We expect most users are loading this via udev and thus
there should be no change to the userland configuration.

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.

Summary of changes:
  1) Remove some unused members from the platform data.
  2) Remove the custom KEY macro and use the ones available in
     <linux/input/matrix_keypad.h>
  3) Remove the keypad_{readl/writel} macros and just use
     __raw_{readl/writel} directly.
  4) Update the clk_set_rate() call to work with the core support.
  5) Cleanup the probe routine and remove some unneeded messages.
  6) Use the ep93xx core functions to acquire and release the gpio's.
  7) Fix the clk_get() call to get the keypad clock.

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver.
 This adds a generic dma_slave pointer to the mci platform structure where
we can store DMA controller information.  In atmel-mci we use information
provided by this structure to initialize the driver (with new helper
functions that are architecture dependant).

This also adds at32/avr32 chip modifications to cope with this new access
method.
