Remove all upstreamed patches and add the kernel configuration for version 5.10. The Rock Pi 4 was split in multiple versions. Add a DTS with the old name in order to keep compatibility while having kernel 5.4 and 5.10 in parallel. Switch to the Rock Pi 4A DTS once Kernel 5.4 support is removed.

RK3328 has one USB 3.0 OTG controller which uses DWC_USB3
|
|
core's general architecture. It can act as static xHCI host
|
|
controller, static device controller, USB 3.0/2.0 OTG basing
|
|
on ID of USB3.0 PHY.

NOTE: This binding still has issues. From the original thread:
|
|
|
|
the rk3328 usb3-phy has an issue with detecting any plugin events
|
|
after a previous device got removed - see the inno-usb3-phy driver
|
|
in the vendor kernel.
|
|
|
|
The current state is good-enough for enabling the USB3 attached LAN
|
|
port of the NanoPi R2S. However, it might explode depending on your
|
|
use-case. You've been warned.
