[PATCH v5 07/12] usb: cdns3-ti: add J7200 support with reset-on-resume behavior

From: Théo Lebrun
Date: Fri Jul 26 2024 - 14:18:20 EST


Add ti,j7200-usb compatible. Match data indicates the controller resets
on resume which tells that to the cdns3 core. This in turn silences a
xHCI warning visible in cases of unexpected resets.

We also inherit the errata quirk CDNS3_DRD_SUSPEND_RESIDENCY_ENABLE from
the default `cdns_ti_auxdata` configuration.
