Subject: [PATCH v3 2/5] arm64: dts: rockchip: Add powerzones definition for rock960
Date: Wed,  1 Dec 2021 17:38:51 +0100	[thread overview]
Message-ID: <20211201163856.41419-2-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20211201163856.41419-1-daniel.lezcano@linaro.org>

Add the powerzones description. This first step introduces the big,
the little as powerzone places.

Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
---
   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
