1 Mediatek SCP Bindings
2 ----------------------------------------
3
4 This binding provides support for ARM Cortex M4 Co-processor found on some
5 Mediatek SoCs.
6
7 Required 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
17 Subnodes
18 --------
19
20 Subnodes of the SCP represent rpmsg devices. The names of the devices are not
21 important. The properties of these nodes are defined by the individual bindings
22 for 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.

27 Example:
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 };
