Subject: [PATCH 0/2] Add bootph-all to SERDES3 for USB DFU Boot on J721E

Hello,

This series is based on linux-next tagged next-20250207.

J721E SoC supports USB DFU Boot via USB0 instance of USB. On both
J721E-EVM - (J721E SoM + J7 Common Processor Board) and
J721E-SK, the USB Type-C interface which is connected to USB0 via
SERDES3 is used for USB DFU boot.

Series adds "bootph-all" tag to the "serdes3_usb_link" device-tree node
which is the USB3 PHY for USB0, thereby enabling USB DFU boot.

Regards,
Siddharth.
