Subject: [PATCH V2 6/9] arm64: dts: imx8mn: add GPC node
Date: Sat,  9 Oct 2021 11:26:56 -0500	[thread overview]
Message-ID: <20211009162700.1452857-7-aford173@gmail.com> (raw)
In-Reply-To: <20211009162700.1452857-1-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.
