c33b1437c0 ARM: dts: at91: at91sam9rl: TC blocks are also simple-mfd and syscon devices
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time and free up the remaining
channels for other use.

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.

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.

138c2b2f17 ARM: dts: at91: fixes dbgu pinctrl, set pullup on rx, clear pullup on tx
Remove pullup on dbgu DTXD signal, it is a push-pull output thus the
pullup is pointless.

Add pullup on dbgu DRXD signal, it prevents the DRXD signal to be left
floating and so consuming a useless extra amount of power in crowbarred
state if nothing is externally connected to dbgu.
