It has been observed that xusbxti clock's default value is not set
because of which there is a divide by zero error in kernel when ASV

Some of the boards under mach-exynos4 initialize frame-buffers
for which the memory requirement is more than 2MB, hence the
default dma pool allocation size of 2MB is not sufficient.
The consistent dma size is hence increased to successfully
allocate memory for those boards.

PDMA controllers when instantiated from device tree are registered using
amba_device_register(). The registration process enables clock to the
controllers to read the peripheral id of the PDMA amba device.
In case of Exynos4, the clocks to the PDMA controllers are named as 'dma'
but amba_device_register() looks up the clock using the name 'apb_pclk'.
Hence, alias clocks with name 'apb_pclk' clock are created for clocks
with name 'dma'.

The pl330 device instances and associated platform data is required only
for non-device-tree builds. With device tree enabled, the data about the
platform is obtained from the device tree. For images that include both
dt and non-dt platforms, an addditional check is added to ensure that
static amba device registrations is applicable to only non-dt platforms.

requesting a dma channel. This request indicates that a device tree
node property represting the dma channel is available in
'struct samsung_dma_info'. The dma channel request wrapper uses the

The dma channel selection filter function is moved from plat-samsung
into the pl330 driver. In additon to that, a check is added in the
filter function to ensure that the channel on which the filter has
been invoked is pl330 channel instance (and avoid any incorrect
access of chan->private in a system with multiple types of DMA
drivers).

being removed, only the driver probe is left over in these extensions. The
probe function itself can be merged into one and moved into the samsung common
serial driver. With driver probe also moved, all the SoC specific extentions
are no longer required and they are deleted.

using clock names communicated between the samsung uart driver and the
SoC specific extension can be removed.
In addition to that, for each platform specific extension, add the
default clock selection, number of clock options for uart baud generator,
clock selection bit mask and shift values which is required by the
clkdev support in samsung uart driver.
The default clock selection value 'def_clk_sel' specifies the default clock
to be used as the source clock for baud rate generator in case the platform
code does not specify the same.

Instead of using clock names supplied in platform data, use a generic
clock name 'clk_uart_baud' to look up clocks. The platform code should
register clocks with the name 'clk_uart_baud' which can be used by the
baud rate generator. The clock lookup and selection of the best clock
as baud rate clock is reworked.
Platform code can specify the clocks that can be used as source for the
baud clock (as supported previously by passing names of clocks). A new
member is added to the platform data 'clk_sel' which holds a bit-field
value with each bit representing a baud source clock. If a bit at any
bit position is set, that clock is looked up to participate in the
selection of the baud clock source.

s3c2440 uses fclk/n (fclk divided by n) clock as one of the possible clocks used
to generate the baud rate clock. The divider 'n' in this case can be logically
represented outside of the uart controller.
This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to
represent the fclk/n clock in the platform code. This clock provides a get_rate
callback that checks the UCON0/1/2 registers to determine the clock rate. The
samsung uart driver would receive the "fclk_n" clock name as one of the possible
baud rate clock options and the driver need not determine clock rate of fclk/n.

The timer irqs statically mapped from linux irq numbers 11 to 15 are
moved to the end of the statically mapped linux irq space. The GIC PPI
and SPI interrupts are relocated to start from 16 and 32 of the linux
irq space. This is a required to add device tree support for GIC and
Interrupt combiner for EXYNOS4.
A new macro 'IRQ_TIMER_BASE' specifies a platform specific base of the
linux virq number for the timer interrupts. For exynos4, this base is
set to end of the linux virq space. For the other S5P platforms, the
existing base '11' is retained.
