Subject: [RFC 2/4] Documentation: bindings: fsl,imx-blk-ctl: Support imx8mn
Date: Sun, 9 May 2021 09:47:09 -0500 [thread overview]
Message-ID: <20210509144711.2192991-3-aford173@gmail.com> (raw)
In-Reply-To: <20210509144711.2192991-1-aford173@gmail.com>
The imx8mn has a similar dispmix to that of the imx8mm, however
there are some additionl power domains that will be needed
for additional peripherals that were not present on the imx8mm,
so it needs a unique blk-ctl.
