Vicentiu Galanopulo 7d5f1dbda1 recipes-kernel/linux: Remove unused patches and householding
Some patches were part of other linux-mainline
kernel versions but are not anymore part of the
current 4.19.76.

Move 0001-Enable-uart3-for-NanoPi-Neo-Air-used-by-BT.patch
in linux-mainline_4.19.76.bbappend to avoid error
patching file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts
Hunk #2 FAILED at 162.
1 out of 2 hunks FAILED -- rejects in file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts

Place all patches from Armbian in a separate directory and do all the Balena specific
operations in linux-mainline_%.bbappend only.

Subject: [PATCH 27/82] arm: dts: sun8i: a83t: a711: update brightness levels
to fit the device
The function is exponential with base of 1.32 and some offset and
tweaks. The lowest values produce no output, so we are starting at 8.
The default brigtness is a bit lower than maximum to boot with reduced
backlight.
