[PATCH v2 1/1] arm64: zynqmp: Enable usb3 for k24 som

Fri Dec 15 08:40:12 CET 2023
Currently, the u-boot zynqmp psgtr driver is not connected to the usb dwc3
driver. Without this, the only way for u-boot to be able to use usb3 is if
the psgtr serdes clocking is already enabled in the psu_init_gpl.c. This
patch enables the psgtr serdes for usb3 use, so the u-boot dwc3 driver will
work properly on boards based on the k24 som.
In addition, this patch correctly configures mio76 and mio77 as gpio pins
which are used as reset gpio pins on the kd240 starter kit.
This patch is needed for enabling u-boot to load an OS on the kd240
starter kit by either usb3 or the sd card interface connected over the usb3
to sd card bridge.
