Subject: [PATCH V4 6/9] arm64: dts: imx8mn: add GPC node
Date: Sun, 28 Nov 2021 07:18:49 -0600 [thread overview]
Message-ID: <20211128131853.15125-7-aford173@gmail.com> (raw)
In-Reply-To: <20211128131853.15125-1-aford173@gmail.com>
Add the DT node for the GPC, including all the PGC power domains,
some of them are not fully functional yet, as they require interaction
with the blk-ctrls to properly power up/down the peripherals.
