-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 at 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";
- };
