Bindings for "fixed-regulator" only explicitly support "gpio" property,
not "gpios". Fix by correcting the property name.
The enet PHYs on imx6sx-sdb needs to be explicitly reset after a power
cycle, this can be handled by the phy-reset-gpios property. Sadly this
is not handled on suspend: the fec driver turns phy-supply off but
doesn't assert phy-reset-gpios again on resume.
Since additional phy-level work is required to support powering off the
phy in suspend fix the problem by just marking the regulator as
"boot-on" "always-on" so that it's never turned off. This behavior is
equivalent to older releases.
Keep the phy-reset-gpios property on fec anyway because it is a correct
description of board design.
This issue was exposed by commit efdfeb079cc3 ("regulator: fixed:
Convert to use GPIO descriptor only") which causes the "gpios" property
to also be parsed. Before that commit the "gpios" property had no
effect, PHY reset was only handled in the the bootloader.
This fixes linux-next boot failures previously reported here:

Fix the following warnings from dtc by adding the unit name to memory
nodes:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
Converted using the following command:
perl -p0777i -e 's/memory \{\n\t\treg = \<0x+([0-9a-f])/memory\@$1$\0000000 \{\n\t\treg = <0x$1/m' `find ./arch/arm/boot/dts -name "imx*"`
The files below were manually fixed:
-imx1-ads.dts
-imx1-apf9328.dts
-imx6q-pistachio.dts

It is preferred to use the panel compatible string rather than passing
the LCD timing in the device tree.
So pass the "sii,43wvf1g" compatible string, which describes the parallel
LCD.
Also pass the 'backlight' property as described in
Documentation/devicetree/bindings/display/panel/simple-panel.txt

It is not recommended to place regulators inside "simple-bus", so
move them out. The motivation for doing this is to make it easier to
adding new regulators.

We need to change trimming value (as a percentage) of the 17.78mA TX
reference current for better signal quality. With this change, we
can pass the eye-diagram test on this board.

As of commit 1006ed7e1b258dac ("serial: imx: Use generic uart-has-rtscts
DT property"), the Freescale IMX UART driver recognizes the generic
"uart-has-rtscts" DT property, deprecating the vendor-specific
"fsl,uart-has-rtscts" DT property. Hence replace the latter by the
former in all DTS files.

Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,wakeup" and "enable-sdio-wakeup" boolean
property to enable the wakeup source, "wakeup-source" is the new
standard binding.
This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios
should be changed to GPIO_ACTIVE_HIGH.
Otherwise, the SD may not work properly due to wrong polarity inversion
specified in DT after switch to common parsing function mmc_of_parse().

The imx6sx sdb board has two revisions, the current mainline one
is reva which is experimental and mainly for internal use. In
this commit, we rename imx6sx-sdb.dts to imx6sx-sdb.dtsi, and
move the reva dedicated contents to imx6sx-sdb-reva.dts.
