[PATCH 03/10] ARM: dts: r8a7791: Add SYSC PM Domains

Simon Horman horms+renesas at verge.net.au
Tue Apr 26 21:20:30 PDT 2016


From: Geert Uytterhoeven <geert+renesas at glider.be>

Add a device node for the System Controller.
Hook up the Cortex-A15 CPU cores and the Cortex-A15 L2 cache/SCU to
their respective PM Domains.
