To: linux-arm-kernel
Add a device node for the System Controller.
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>
---
v5:
- Remove "power-domains" property again from the sysc node, as the
System Controller itself is not part of the Clock Domain,
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.

Hook up all devices that are part of the CPG/MSTP Clock Domain to the
SYSC "always-on" PM Domain, for a more consistent device-power-area
description in DT.

Hi Geert,
Thank you for the patches.
For the whole series,
Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
