* ARM Versatile Express Serial Power Controller device tree bindings
Latest ARM development boards implement a power management interface (serial
power controller - SPC) that is capable of managing power/voltage and
operating point transitions, through memory mapped registers interface.
On testchips like TC2 it also provides a configuration interface that can
be used to read/write values which cannot be read/written through simple
memory mapped reads/writes.
- spc node
- compatible:
Usage: required
Value type: <stringlist>
Definition: must be
"arm,vexpress-spc,v2p-ca15_a7","arm,vexpress-spc"
- reg:
Usage: required
Value type: <prop-encode-array>
Definition: A standard property that specifies the base address
and the size of the SPC address space
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: SPC interrupt configuration. A standard property
that follows ePAPR interrupts specifications
Example:
spc: spc@7fff0000 {
compatible = "arm,vexpress-spc,v2p-ca15_a7","arm,vexpress-spc";
reg = <0 0x7FFF0000 0 0x1000>;
interrupts = <0 95 4>;
};
