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.

Subject: [PATCH] net: usb: r8152: add LED configuration from OF
|
|
|
|
This adds the ability to configure the LED configuration register using
|
|
OF. This way, the correct value for board specific LED configuration can
|
|
be determined.
