In Linux 5.10.24 a regression has been introduced which broke reboot on ODROID-N2(+). Interestingly the patch should improve reboot stability for VIM3, which uses the same SoC. However, it seems that in the ODROID-N2 case, this causes more problems then it fixes. Revert the offending patch.

Subject: [PATCH 3/5] arm64: dts: meson: g12b: add GPIO fan support
|
|
|
|
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.
