Add a device node for the System Controller, with subnodes that represent the hardware power area hierarchy. 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> --- v2: - Change one-line summary prefix to match current arm-soc practices, - Update compatible values. --- arch/arm/boot/dts/r8a7794.dtsi | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+)
