Sylvain Rochet 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.

Alexandre Belloni e152e3f7f4 ARM: dts: at91: fix i2c-gpio node name
i2c-gpio doesn't need a reg property. Change the node names to i2c-gpio-x
as used in other dts to remove the unit-address.

Solves:
Warning (unit_address_vs_reg): Node /i2c@0 has a unit name, but no reg property
Warning (unit_address_vs_reg): Node /i2c@1 has a unit name, but no reg property
Warning (unit_address_vs_reg): Node /i2c@2 has a unit name, but no reg property

Alexandre Belloni 620f503322 ARM: at91/dt: use syscon for PMC
The PMC is not only used to drive the clocks but also has some registers
related to other functions. One of those is for example the USB gadget
bias.
Using a syscon allows to properly separate those functions.

Linus Torvalds 3d9f96d850 ARM: SoC: DT updates for v4.2
As usual, quite a few device-tree updates in ARM land.  There was ome
 minor churn in DTs due to relicensing under a dual-license, and lots
 of little additions of new peripherals, features etc, but nothing
 really exciting to call to your attention.  Some higlights, focsuing
 on support for new SoCs and boards:
