1Mediatek SCP Bindings 2---------------------------------------- 3 4This binding provides support for ARM Cortex M4 Co-processor found on some 5Mediatek SoCs. 6 7Required properties: 8- compatible Should be "mediatek,mt8183-scp" 9- reg Should contain the address ranges for memory regions: 10 SRAM, CFG, and L1TCM. 11- reg-names Contains the corresponding names for the memory regions: 12 "sram", "cfg", and "l1tcm". 13- clocks Clock for co-processor (See: ../clock/clock-bindings.txt) 14- clock-names Contains the corresponding name for the clock. This 15 should be named "main". 16 17Subnodes 18-------- 19 20Subnodes of the SCP represent rpmsg devices. The names of the devices are not 21important. The properties of these nodes are defined by the individual bindings 22for the rpmsg devices - but must contain the following property: 23 24- mtk,rpmsg-name Contains the name for the rpmsg device. Used to match 25 the subnode to rpmsg device announced by SCP. 26 27Example: 28 29 scp: scp@10500000 { 30 compatible = "mediatek,mt8183-scp"; 31 reg = <0 0x10500000 0 0x80000>, 32 <0 0x105c0000 0 0x5000>; 33 reg-names = "sram", "cfg"; 34 clocks = <&infracfg CLK_INFRA_SCPSYS>; 35 clock-names = "main"; 36 }; 37
