[PATCH v6 1/6] dt-bindings: remoteproc: mediatek: Add binding for mt8195 scp

[Tinghan Shen]

Add mt8195 compatible to binding document. The description of required
properties are also modified to reflect the hardware change between
mt8183 and mt8195. The mt8195 doesn't have to control the scp clock on
kernel side.

-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";
