ARM: imx: initial SolidRun HummingBoard support
Add support for the SolidRun HummingBoard. This commit adds support for
the following interfaces on this board:
- Consumer Ir receiver
- S/PDIF output
- Both USB interfaces
- Gigabit Ethernet using AR8035
- UART port
shawn.guo:
- Add pinctrl_hummingboard_i2c1 and pinctrl_microsom_uart1 to replace
pinctrl_i2c1_1 and pinctrl_uart1_1
- Use generic name for fixed voltage regulator nodes
- Fix commment format in mach-imx6q.c
- Move ar8035_phy_fixup around to put PHY_ID_AR8031 and PHY_ID_AR8035
together

ARM: dts: imx: specify the value of audmux pinctrl instead of 0x80000000
We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.
This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).
This patch updates i.MX51 CPU node:
- Alias for CPU is added to allow using this node in the parent DTS files.
- Removed useless "clock_names" property.
- "clock-latency" value increased to safe using with 32 kHz OSC.
- Defined operating points voltages and "voltage tolerance" properties.
Values are safe for both commercial and industrial CPU variants.
