The remaining contents of LC0 are only used after the point in the
decompressor startup code where we enter via 'wont_overwrite'. So
move the loading of the LC0 structure after it. This will allow us
to jump to wont_overwrite directly from the EFI stub, and execute
the decompressor in place at the offset it was loaded by the UEFI
firmware.

In preparation of moving the handling of the LC0 object to a later stage
in the decompressor startup code, move out _edata and the initial value
of the stack pointer, which are needed earlier than the remaining
contents of LC0.

Move mmc nodes to be compatible with the sdhci-omap driver. The following
modifications are required for omap_hsmmc specific properties:
ti,non-removable: convert to the generic mmc non-removable
ti,needs-special-reset: co-opted into the sdhci-omap driver
ti,dual-volt: removed. Legacy property not used in am335x or am43xx
ti,needs-special-hs-handling: removed. Legacy property not used in am335x
or am43xx
Also since the sdhci-omap driver does not support runtime PM, explicitly
disable the mmc3 instance in the dtsi.

Before breaking up LC0 into different pieces, move out the variable
that is already place-relative (given that it subtracts 'restart' in
the expression) and so its value does not need to be added to the
runtime address of the LC0 symbol itself.

The Mecer Xtreme Mini S6 features a wireless module, based on a
Realtek 8723BS, which provides WLAN and Bluetooth connectivity via
SDIO and UART interfaces respectively.
Define a simple MMC power sequence that declares the GPIO pins
connected to the module's WLAN Disable and Bluetooth Disable pins
as active low reset signals, because both signals must be deasserted
for WLAN radio operation.
Configure the host's SDIO interface for High Speed mode with 1.8v
I/O signalling and IRQ detection over a 4-bit wide bus.

Current dts files with 'gpio-led' nodes were manually verified.
In order to automate this process leds-gpio.txt
has been converted to yaml. With this conversion a check
for pattern properties was added. A test with the command
below gives a screen full of warnings like:
arch/arm/boot/dts/rk3188-radxarock.dt.yaml: gpio-leds:
'blue', 'green', 'sleep'
do not match any of the regexes:
'(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'
Fix these errors with help of the following rules:
1: Add nodename in the preferred form.
2: Always add a label that ends with '_led' to prevent conflicts
with other labels such as 'power' and 'mmc'
3: If leds need pinctrl add a label that ends with '_led_pin'
also to prevent conflicts with other labels.
patternProperties:
# The first form is preferred, but fall back to just 'led'
# anywhere in the node name to at least catch some child nodes.
"(^led-[0-9a-f]$|led)":

The common LED binding wants the LED node names to start with led- and
then have just a single number.
Changing the naming for the 8 user LEDs from using user<x> to led-<x>.
Also there is no default-trigger named "mmc0" in the kernel, so use the
more generic "disk-activity".

Users can choose which flexcom function to use. Describe the I2C
Flexcom0 function. Add alias for the i2c2 node in order to not rely
on probe order for the i2c device numbering. The sama5d2 SoC has
two dedicated i2c buses and five flexcoms that can function as i2c.
The i2c0 and i2c1 aliases are kept for the dedicated i2c buses,
the i2c flexcom functions can be numbered in order starting from i2c2.

Device aliases are board-specific, if needed one should define them
in board dts rather than in the SoC dtsi. If an alias from the SoC
dtsi is addressed by a driver that does not use any of the of_alias*()
methods, we can drop it. This is the case for the i2s aliases, drop
them. tcb aliases point to nodes that are not enabled in any of the
sama5d2 based platforms. atmel_tclib.c is scheduled to go away, any
board using that alias is already broken, so get rid of the tcb aliases
too.

The Flexcom IP is part of the sama5d2 SoC. Move the flx0 node together
with its function definitions in sama5d2.dtsi. Boards will just fill
the pins and enable the desired functions.
There is a single functional change in this patch. With the move of the
flx0 uart5 definition in the SoC dtsi, the uart5 from
at91-sama5d27_wlsom1_ek.dts inherits the following optional property:
atmel,fifo-size = <32>;
