Add a device node for the System Controller, and hook it up to the CPG/MSTP Clock Domain. Hook up the Cortex-A7 CPU cores and the Cortex-A7 L2 cache/SCU to their respective PM Domains. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- v4: - Add power-domains property to the sysc node, to refer to the SoC's Clock Domain, v3: - Drop power area hiearchy from DT, - Switch to "#power-domain-cells = <1>", - Drop fallback compatibility strings, v2: - Change one-line summary prefix to match current arm-soc practices, - Update compatible values. --- arch/arm/boot/dts/r8a7794.dtsi | 11 +++++++++++ 1 file changed, 11 insertions(+)
