|

>>>>>>> be3afe8b (Update to Linux 5.10.53 (#1475)):buildroot-external/board/hardkernel/patches/linux/5.10.53/0005-arm64-dts-meson-g12b-add-GPIO-fan-support.patch
|
|
|
|
Add simple GPIO fan node to support a fan on GPIO J8. Unfortunately the
|
|
pad used to control the fan does not support real PWM, hence the RPM
|
|
cannot be modulated.
