[PATCH v4 15/18] arm64: dts: imx8mm: put USB controllers into power-domains

From: Lucas Stach <l.stach@pengutronix.de>
Date: 2021-09-10 20:27:07
Also in: linux-devicetree
Subsystem: arm/freescale imx / mxc arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

Now that we have support for the power domain controller on the i.MX8MM
we can put the USB controllers in their respective power domains to allow
them to power down the PHY when possible.
