Mediatek SCP Bindings
|
||
|
|
----------------------------------------
|
||
|
|
|
||
|
|
This binding provides support for ARM Cortex M4 Co-processor found on some
|
||
|
|
Mediatek SoCs.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible Should be "mediatek,mt8183-scp"
|
||
|
|
- reg Should contain the address ranges for the two memory
|
||
|
|
regions, SRAM and CFG.
|
||
|
|
- reg-names Contains the corresponding names for the two memory
|
||
|
|
regions. These should be named "sram" & "cfg".
|
||
|
|
- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
|
||
|
|
- clock-names 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";
|
||
|
|
};
