Add a device node for the System Controller, with subnodes that represent the hardware power area hierarchy. Hook up the first Cortex-A15 CPU core and the Cortex-A15 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/r8a7793.dtsi | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+)
