Subject: [PATCH V2 6/7] ARM64: dts: imx8mm: Fix clocks and power domain for USB OTG
Date: Fri, 13 Dec 2019 10:05:41 -0600	[thread overview]
Message-ID: <20191213160542.15757-7-aford173@gmail.com> (raw)
In-Reply-To: <20191213160542.15757-1-aford173@gmail.com>

There are two USB OTG controllers on the i.MX8M Mini, but currently
neither are functional.

According to the device tree entries published on the NXP kernel
for the imx8m mini, these both need to be assigned to the proper
clocks and power domain in order to function.

This patch configures both USB OTG controllers to enable a missing
clock and define the power domain so boards wishing to enable
the USB OTG can do so.
