Subject: [ARM] dma: pata_icside's contiguous sg array is now redundant

Now that the IOMD DMA code walks the scatterlist using sg_next,
converting the sg list into a contiguous list is no longer required.

Subject: [ARM] dma: Use sensible DMA parameters for Acorn drivers

The hardware supports transfers up to a page boundary per buffer.
Currently, we work around that in the DMA code by splitting each
buffer up as we run through the scatterlist.  Avoid this by telling
the block layers about the hardware restriction.

Eventually, this will allow us to phase out the splitting code,
but not until the old IDE layer allows us to control the value it
gives to blk_queue_segment_boundary().

Subject: [ARM] omap: i2c: remove armxor_ck

On OMAP1, the I2C functional clock (fck) is the armxor_ck, so there's
no need to get "armxor_ck" separately.

Subject: [ARM] omap: i2c: remove conditional ick clocks

By providing a dummy ick for OMAP1510 and OMAP310, we avoid having
SoC conditional clock information in i2c-omap.c.  Also, fix the
error handling by making sure we propagate the error returned via
clk_get().

Subject: [ARM] 5394/1: Add static bus numbering support to i2c-versatile

If dev->id is not -1, the platform code may use static bus numbering
rather than dynamic. The patch also changes the i2c_versatile_init to a
subsys_initcall rather than module_init to make sure it is initialised
before the I2C devices initialisation.

Subject: i.MX31: framebuffer driver

This is a framebuffer driver for i.MX31 SoCs. It only supports synchronous
displays, vertical panning supported, no overlay support.

Subject: [ARM] pxa: move DMA registers definitions into <mach/dma.h>

1. Driver code where pxa_request_dma() is called will most likely
   reference DMA registers as well,  and it is really unnecessary
   to include pxa-regs.h just for this. Move the definitions into
   <mach/dma.h> and make relevant drivers include it instead of
   <mach/pxa-regs.h>.

2. Introduce DMAC_REGS_VIRT as the virtual address base for these
   DMA registers. This allows later processors to re-use the same
   IP while registers may start at different I/O address.

Subject: [ARM] pxa: remove machine class specific stuffs from serial driver

The only things prevent drivers/serial/pxa.c from being generic enough
are:

  1. IER_UUE which can be safely replaced by UART_IER_UUE as defined in
     serial_reg.h for PXA

  2. __PREG() and FFUART/BTUART/STUART definitions to decide the UART
     port name

And removed the un-necessary #include of <mach/...> and <asm/...> headers.

Subject: [ARM] pxa: remove unnecessary #include of pxa-regs.h and hardware.h

pxa-regs.h and hardware.h are not intended for use directly in driver
code, remove those unnecessary references.

Subject: [ARM] pxa: move PCMCIA definitions out of pxa-regs.h into
 pxa2xx_base.c

Move the processor specific initialization (largely resources initialization)
out of soc_common_drv_pcmcia_probe() into dedicated sa11xx_drv_pcmcia_probe()
and __pxa2xx_drv_pcmcia_probe().

By doing this, we are now able to move the PCMCIA related definitions out of
pxa-regs.h and back into pxa2xx_base.c.

As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.

Subject: [ARM] pxa: move pxa2xx chip selects definitions out of pxa-regs.h

The definitions of PXA_CS<x>_PHYS are really PXA2xx specific and should
be moved out of pxa-regs.h. As an illustration, the PXA3xx static chip
selects definitions are added into pxa3xx-regs.h.

Subject: [ARM] pxa: separate definitions from pxa-regs.h and remove it finally

The remaining registers are separated into:

   - <mach/regs-ost.h>
   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:

1. include the specific <mach/regs-*.h> with care (if that's absolutely
   necessary)

2. define the registers in the driver, make cleanly defined API to expose
   the register access to external with sufficient reason

Subject: [ARM] MXC: remove _clk suffix from clock names

The context makes it clear already that these are clocks, so there's
no need for such a suffix. This patch only changes the clocks actually
used in the tree. The remaining clocks are renamed in the subsequent
architecture specific patches.

    instead of MHz.

Subject: imxfb: Fix TFT mode

We read from the PCR reg to determine whether to use TFT mode or not.
This is not possible because it may not have been initialized with
the correct value yet. Select it using fbi->pcr instead.
