This patch splits the M28EVK device tree file into a common SoM
part and an EVK part. This is needed to make it easier for users
of the SoM to put it into different, non-reference baseboard.

The pins have nothing todo with the phy layer. We better rename them, so
it gets clear they are routed to the ehci core not to any phy.

The device tree specification recommends that generic name should be
used for nodes. So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

Convert mx23/mx28 dts files to use the padconfig defintions from

Convert mx23/mx28 dts filed to use the pinctrl header files.
NOTE: During automatic conversion of these files to use the pinconfig
definitions an inconsistency has been found in:
arch/arm/boot/dts/imx28-apx4devkit.dts
According to the comment the function for pad SSP2_SS0 should have
been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131
represents: MX28_PAD_SSP2_SS0__AUART3_TX
I used the later (though probably wrong) definition because that's
what is actually being used in the DTB.

These systems all use saif0 as the mclock provider to codec sgtl5000.
Reflect that in device tree source, so that sgtl5000 can find the clock
by calling clk_get().

Make use of RTS/CTS lines on AUART0 and register AUART1 and AUART2
which are routed onto a pin header.

This is support for the ARM Chromebook, originally scheduled
as a "late" pull request. Since it's already late now, we
can combine this into the existing next/dt2 branch.
* late/dt:
ARM: exynos: dts: cros5250: add EC device
ARM: dts: Add sbs-battery for exynos5250-snow
ARM: dts: Add i2c-arbitrator bus for exynos5250-snow
ARM: dts: Add chip-id controller node on Exynos4/5 SoC
ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree
Move display timing configurations into device tree, so that the
auxdata for mxsfb driver can be killed.

Put the clock to the devicetree, so the driver can take care of it
later. Then, we don't have to do the enabling as a workaround in board
init.

[shawn.guo: add enet_out into imx28.dtsi and overwrite it for m28evk]

Slow down the I2C clock speed on M28 and SPS1 as it turns out the
I2C block in i.MX28 can not operate stable enough with the bus
running at 400kHz. Note that the driver used by Freescale runs
the bus at 250kHz when 400kHz speed is selected, but the mainline
Linux kernel runs the bus at actual 400kHz and that's where it is
occasionally unstable. Play safe and run the bus at 100kHz.

Update the mach-mxs machine by removing the enet_clkout(). The new
revision of the board doesn't need that. Also, update the DTS file
with all the new drivers pulled in the mainline recently, that is,
SPI, LRADC, USB.

Rename mxs dts files with soc name being the prefix, so that the board
dts file can be located easily by soc name, and we also gain the
consistency of naming.
