| |
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.
