Mediatek SCP Bindings

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

This binding provides support for ARM Cortex M4 Co-processor found on some

Mediatek SoCs.

Required properties:

- compatible		Should be one of:

				"mediatek,mt8183-scp"

				"mediatek,mt8192-scp"

				"mediatek,mt8195-scp"

- reg			Should contain the address ranges for memory regions:

			SRAM, CFG, and L1TCM.

- reg-names		Contains the corresponding names for the memory regions:

			"sram", "cfg", and "l1tcm".

- clocks		Required by mt8183 and mt8192. Clock for co-processor

			(See: ../clock/clock-bindings.txt)

- clock-names		Required by mt8183 and mt8192. Contains the

			corresponding name for the clock. This should be

			named "main".

Subnodes

--------

Subnodes of the SCP represent rpmsg devices. The names of the devices are not

important. The properties of these nodes are defined by the individual bindings

for the rpmsg devices - but must contain the following property:

- mtk,rpmsg-name	Contains the name for the rpmsg device. Used to match

			the subnode to rpmsg device announced by SCP.

Example:

	scp: scp@10500000 {

		compatible = "mediatek,mt8183-scp";

		reg = <0 0x10500000 0 0x80000>,

		      <0 0x105c0000 0 0x5000>;

		reg-names = "sram", "cfg";

		clocks = <&infracfg CLK_INFRA_SCPSYS>;

		clock-names = "main";
