Subject: [PATCH V4 7/9] arm64: dts: imx8mn: put USB controller into power-domains
Date: Sun, 28 Nov 2021 07:18:50 -0600	[thread overview]
Message-ID: <20211128131853.15125-8-aford173@gmail.com> (raw)
In-Reply-To: <20211128131853.15125-1-aford173@gmail.com>

Now that we have support for the power domain controller on the i.MX8MN,
we can put the USB controller in the respective power domain to allow
it to power down the PHY when possible.
