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 028/146] iio: adc: sun4i-gpadc-iio: add support for A80
|
|
thermal sensor
|
|
|
|
This patch adds support for the A80 ths sensor.
|
|
|
|
The A80 has 4 sensors and supports interrupts. The interrupt is configured to update
|
|
the sensor values every second. The A80 shares some registers with the
|
|
integrated GPADC. ACQ0 must be set in the GPADC register with the offset
|
|
0x00. In fact the GPADC and the THS use the same register base and also
|
|
the same clocks and resets.
