Tomasz Figa db9f31696a ARM: dts: Work around lack of cpufreq regulator lookup for exynos4210-origen and trats boards
Exynos cpufreq drivers does not support device tree based regulator
lookup, so it can get the VDD ARM regulator only by its name. To get
cpufreq working for now, this patch works this around by renaming the
regulator in board dts files to vdd_arm, which is the name expected by
the driver.

This fixes a regression introduced by dropping support of board file
based bootup of Exynos 4210 boards that rendered cpufreq inoperable on
Trats and Origen boards.

Andrzej Hajda b75e2e3d28 ARM: dts: Add S5K5BA sensor regulator definitions for Trats board
Add MAX8998 LDO12 and fixed voltage regulator nodes. While at it,
all fixed voltage regulator nodes are grouped in a 'regulators' node.

Sylwester Nawrocki 39a11311a7 ARM: dts: Add FIMC nodes for Exynos4210 Trats board
Enable FIMC devices on the Trats board. This allows using the
device in memory-to-memory mode only. The camera port pinctrl
property is now empty and will be updated while support for the
camera sensors is added.

Thomas Abraham 8b6076d47f ARM: dts: add board specific fixed rate clock nodes for Exynos based platforms
The clock frequency of xxti and xusbxti clocks is dependent on the
frequency of the on-board oscillator that is used to generate these
clocks. So allow the frequency of these clocks to be specfied from
device tree.

Tomasz Figa d36bb0f040 ARM: dts: Remove broken-voltage property from sdhci node for exynos4210-trats
The broken voltage property has been replaced with auto detection based
on voltages available on vmmc voltage regulator, so there is no use for
it now.

This patch removes the now unused property from Trats Device Tree
sources.

Since the maximum section size on mach-exynos is set to 256MiB, boards
with memory configuration defined using sections bigger than 256MiB will
fail to boot with a kernel panic.

This patch modifies the dts file of Samsung Trats board to define four
sections of 256MiB instead of two of 512MiB to fix the boot problem.
