[PATCH 0/7] rockchip: Enable USB support for RK3528

[Jonas Karlman]

This series picks USB related DT commits from v7.2-rc1-dts to enabled
USB support on existing RK3528 boards. It also adds required DT nodes
and enables required Kconfig options on the Generic RK3528 target.

The 'Add watchdog node for RK3528' commit was included to fully sync
RK3528 DTs up to v7.2-rc1 state, it is not required for USB support.

USB has been verified working on following boards using both generic and
the board specific defconfig target.

- ArmSoM Sige1
- FriendlyElec NanoPi Zero2
- Radxa E20C
- Radxa ROCK 2F

Please note that the dts/upstream related patches should be applied
after v7.1-dts has been fully pulled into dts/upstream.
