From 422b3e199316b9794e400ea1519505cb0609dfc3 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Tue, 16 Feb 2021 22:06:12 +0100 Subject: rockchip: add Kernel 5.10 support 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.
