Rob Herring 8dccafaa28 arm: dts: fix unit-address leading 0s
Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'

Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

Boris Brezillon 1004a2977b ARM: dts: at91: Switch to the new NAND bindings
Use the new EBI/NAND bindings to declare NAND chips and remove old NAND
nodes along the way.

Note that we keep using old bindings in at91rm9200.dtsi because this
SoC is not supported by the EBI driver.

useful for automation and kernelci were a kernel with PROVE_LOCKING enabled

vcc_3v3_reg and vcc_mmc1_reg are fixed regulators and don't need a reg

Warning (unit_address_vs_reg): Node /fixedregulator@1 has a unit name, but no reg property

No interrupt were received from the phy because PIOE 1 may not be properly
muxed. It prevented proper link detection, especially since commit
321beec504 ("net: phy: Use interrupts when available in NOLINK state")

Sudeep Holla 67ae8b9b78 ARM: at91/dt: replace gpio-key,wakeup with wakeup-source property
Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.
