Subject: [PATCH v2 3/3] riscv: dts: allwinner: d1: Add power controller node
Date: Thu, 26 Jan 2023 00:34:19 -0600	[thread overview]
Message-ID: <20230126063419.15971-4-samuel@sholland.org> (raw)
In-Reply-To: <20230126063419.15971-1-samuel@sholland.org>

The Allwinner D1 family of SoCs contain a PPU power domain controller
separate from the PRCM. It can power down the video engine and DSP, and
it contains special logic for hardware-assisted CPU idle.
