Merge branch 'reset/for-4.8-2' into next/dt 

Merging this in avoids a build error that was missed earlier:

In file included from ../arch/arm/boot/dts/meson8b-mxq.dts:48:0:
../arch/arm/boot/dts/meson8b.dtsi:49:53: fatal error: dt-bindings/reset/amlogic,meson8b-reset.h: No such file or directory

* reset/for-4.8-2:
  dt-bindings: reset: Add bindings for the Meson SoC Reset Controller
  reset: Add support for the Amlogic Meson SoC Reset Controller
  reset: Return -ENOTSUPP when not configured
  reset: oxnas: Use devm register API and get rid of platform remove
  reset: fix Kconfig menu to include reset drivers in sub-menu
  reset: zynq: use devm_reset_controller_register()
  reset: socfpga: use devm_reset_controller_register()
  reset: sunxi: use devm_reset_controller_register()
  reset: pistachio: use devm_reset_controller_register()
  reset: ath79: use devm_reset_controller_register()
  reset: add devm_reset_controller_register API

Amlogic Meson SoC Reset Controller

=======================================



Please also refer to reset.txt in this directory for common reset

controller binding usage.



Required properties:

- compatible: Should be "amlogic,meson8b-reset" or "amlogic,meson-gxbb-reset"

- reg: should contain the register address base

- #reset-cells: 1, see below



example:



reset: reset-controller {

	compatible = "amlogic,meson-gxbb-reset";

	reg = <0x0 0x04404 0x0 0x20>;

	#reset-cells = <1>;

};
