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";
};
