Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
The GPIO numbering has changed and is not stable. As a result fan
control via gpio_switch is broken, resulting in errors:
"export_store: invalid GPIO 456"
Move to using hwmon and gpio-fan. This is by adding gpio_fan_array to
DTS and kmod-hwmon-gpiofan to DEVICE_PACKAGES.
In combination with the new rtl8231 gpio driver the default fan
behaviour will be maximum fan speed.
Bump compat value to 1.1 due to existing config in /etc/config/system
via gpio_switch. Also notify in device compat that fan is now going to
be at bootloader setting (maximum in this case) by default unless turned
down.
