ARM: dts: i.MX8MQ: Add Cortex-M4 Coprocessor node
The i.MX8MQ has a Cortex-M4 Coprocessor. Add a node for controlling it.
To make use of it the board has to provide the reserved memory nodes,
for example:
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
m4_reserved: m7@0x40000000 {
no-map;
reg = <0 0x40000000 0 0x1000000>;
};
m4_reserved_sysmem3: rproc@80000000 {
reg = <0 0x80000000 0 0x800000>;
no-map;
};
};
&remoteproc_cm4 {
memory-region = <&m4_reserved>, <&m4_reserved_sysmem3>;
};
