There are 2 revisions of the Exynos5250 Snow Chromebook that were
shipped: Rev4 and Rev5. The only difference between these 2 revisions
is the codec, Rev4 has a max98095 codec while Rev5 has a max98090.

Mainline only supports Rev4 so this patch moves the common device
nodes to a DTSI file and adds a DTS for the Exynos5250 Snow Rev5.

The Snow Rev5 DTS is based on the DTS found in the ChromiumOS 3.8
tree.

Add Hardkernel Odroid XU4 board Device Tree sources. The board differs
from Odroid XU3 and XU3-Lite by:
1. No green and red LEDs (except standard red power LED).
2. Only two PWM outputs are used (fan and blue LED)
3. No audio codec.
4. Two USB3 ports in host mode (no micro USB3 connector for OTG).
5. Realtek RTL8153-CG gigabit network adapter (instead of SMSC9514).
6. Additional connector with IO ports (I2S_0, I2C_5).
7. No DisplayPort (like XU3-Lite).
8. No TI INA231 power measurement sensors (like XU3-Lite).

The Odroid XU3 family boards have ACOKB pin of PMIC grounded, instead of
pulled up as usual. This means that PMIC must manually set PWRHOLD field
in its CTRL1 register to low before initiating power down.

This fixes Odroid XU3 powering off:
[   25.966053] reboot: Power down
[   25.967679] Power down.
[   26.070174] Power down failed, please power off system manually.

The LEDs on Odroid XU3 family boards could not properly probe
because PWM outputs were reduced only to PWM for fan. Fix it
for Odroid XU3 and XU3-Lite boards by switching to usage of
all 4 outputs (although the PWM for MIPI probably is redundant
because board does not have MIPI connector available).

This fixes warnings on dmesg:
[    4.838712] samsung-pwm 12dd0000.pwm: tried to request PWM channel 1 without output
[    4.838725] leds_pwm pwmleds: unable to request PWM for green:mmc0: -22

Current base address is wrong by 0x04 bytes for AHB bus device as shown
in dmesg:

	tegra-ahb 6000c004.ahb: incorrect AHB base address in DT data - enabling workaround

To correct old DTBs, commit ce7a10b0 ("ARM: 8334/1: amba: tegra-ahb:
detect and correct bogus base address") checks for the low bit of the
base address and removes theses 0x04 bytes at runtime.

This patch fixes the original DTS, so upstream version doesn't need the
workaround of the base address.

As both addresses are valid, this patch doesn't break compatibility.

When getting translated from a downstream device tree that used slightly
different DT bindings, these regulators got labeled with the

The sp810 clk driver is calling the clk consumer APIs from
clk_prepare ops to change the parent to a 1 MHz fixed rate clock
for each of the clocks that the driver provides. Use
assigned-clock-parents for this instead of doing it in the driver
to avoid using the consumer API in provider code. This also
allows us to remove the usage of clk provider APIs that take a
struct clk as an argument from the sp810 driver.
