Since we dropped the big chunk of armbian patches let's add back the patches that enabled configfs of uart3 for bluetooth on NanoPi Neo Air. The patches are taken from https://github.com/armbian/build/tree/sunxi-5.5/patch/kernel/sunxi-current Signed-off-by: Florin Sarbu <florin@balena.io>
This patch needs to be redone for the newer kernel the BSP layer now has. We'll just make sure we remove the BSP version and add the reworked one. Signed-off-by: Florin Sarbu <florin@balena.io>
