Subject: [PATCH v4 2/5] arm64: dts: rockchip: Add powerzones definition for rock960
Date: Mon, 6 Dec 2021 00:15:54 +0100 [thread overview]
Message-ID: <20211205231558.779698-2-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20211205231558.779698-1-daniel.lezcano@linaro.org>
Add the powerzones description. This first step introduces the big,
the little as powerzone places.

V4:
- Added missing powerzone-cells
- Changed powerzone name to comply with the pattern property
V3:
- Remove GPU section as no power is available (yet)
- Remove '#powerzone-cells' conforming to the bindings change
V2:
- Move description in the SoC dtsi specific file
V1: Initial post
