[PATCH 1/1] ARM: dts: ls1021a-twr: disable USB2 by default

From: Frank . Li

Date: Wed Oct 21 2026 - 16:50:43 EST


From: Li Yang <leoyang.li@xxxxxxx>

The TWR-ls1021a board doesn't have the USB2 port natively. However the
USB2 pins are routed to the ELEV expansion ports and only available with
TWR-SER2 board connected. So disable the USB2 by default and users
of TWR-SER2 board should update the dts to enable it or apply an
additional overlay.
