7fca1f20c0 ARM: u300: switch to using syscon regmap for board
This switches the code using a local remapping of the
system controller to enable the U300 board to be
self-powered over to making the U300-specific syscon
compatible with the MFD generic syscon driver, selecting
the generic syscon driver, and augmenting the board
power code to pick the regmap and manipulate the syscon
from the regmap side of things.

bba5f2cc2f ARM: u300: move the gated system controller clocks to DT
This moves the slow, fast, AHB bridge and "rest" clocks on
the U300 system controller over to registration from the
device tree.

14c2607144 clk: move the U300 fixed and fixed-factor to DT
This converts the fixed and fixed-factor clocks in the U300
platform to register themselves from the device tree.

cf0ce095c9 ARM: u300: add syscon node
This adds a device tree node for the U300 system controller
and remaps this dynamically instead of using hard-coded
virtual addresses. The board power set-up code is altered
to fetch a reference to the syscon using ampersand <&syscon>
notation. This way of passing a pointer to the syscon will
also be used by the clocks.

d134636f37 ARM: u300: add FSMC flash into the device tree
This registers the U300 FSMC flash controller from the
device tree, and defines the three partitions. Skip the
BBT scan as in the current platform data.

cf4af8670b ARM: u300: add SPI PL022 to the device tree
This registers the PL022 PrimeCell from the U300 device
tree. We make a new copy of the platform data for the
device tree boot path, as the old platform data is in an
older file which will be going away.

39738cc96b ARM: u300: add the COH 901 318 DMAC to device tree
This adds the COH 901 318 DMA controller to the U300
device tree. All devices now converted to device tree
so far will start to find their DMA channels.

Note that the U300 is not yet using the device tree
to obtain DMA channels, but this is a first step.

efb9bc2ea0 ARM: u300: augment device tree with DMA channels
This adds DMA channel assignments to the MMC/SD-controller
and the two UARTs already in the U300 device tree, as we
have now defined a way to obtain DMA channels from the
device tree.

ecf5b39a8b ARM: u300: support regulators in the device tree
Now that we have enabled board power and the AB3100 regulators,
put the regulator data into the device tree and enable it so
we can start to tie regulators to devices. To begin with we're
only supplying the power to the board itself.
