  reg-names:
    items:
      - sram
      - cfg

  clock-names:
    const: main

The old binding, and the comment about clocks above, says that clocks
and clock-names are required for mt8183 and mt8192.

What additional properties do you expect?

Skip soc and the two #-cells, and rewrite the reg to only use 1 address
and size-cell.

The label doesn't add value in the example, please skip this.

Can you please also add a subnode, to capture that part of the binding
as well?

-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>,
