Merge tag 'devicetree-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux 

Pull Devicetree updates from Rob Herring:

 - a bunch of DT binding conversions to DT schema format

 - clean-ups of the Arm idle-states binding

 - support a default number of cells in of_for_each_phandle() when the
   cells name is missing

 - expose dtbs_check and dt_binding_check in the make help

 - convert writting-schema.md to ReST

 - HiSilicon reset controller binding updates

 - add documentation for MT8516 RNG

Amlogic Meson Firmware registers Interface

------------------------------------------



The Meson SoCs have a register bank with status and data shared with the

secure firmware.



Required properties:

 - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon"



Properties should indentify components of this register interface :



Meson GX SoC Information

------------------------

A firmware register encodes the SoC type, package and revision information on

the Meson GX SoCs.

If present, the following property should be added :



Optional properties:

  - amlogic,has-chip-id: If present, the interface gives the current SoC version.



Example

-------



ao-secure@140 {

	compatible = "amlogic,meson-gx-ao-secure", "syscon";

	reg = <0x0 0x140 0x0 0x140>;

	amlogic,has-chip-id;

};
