[PATCH] arm64: dts: rockchip: enable automatic fan control on Orange Pi 5+
Posted by Florian Klink 2 months, 1 week ago
This links the PWM fan on Orange Pi 5+ as an active cooling device
managed automatically by the thermal subsystem, with a target SoC
temperature of 65C and a minimum-spin interval from 55C to 65C to
ensure airflow when the system gets warm.

This is pretty much the same as '4a152231b050 ("arm64: dts: rockchip:
enable automatic fan control on Rock 5B")', except for the Orange Pi
5+ board.

Thanks for renumbering these cooling maps.  It's just that you
missed to label this patch as the v2, i.e. you should have used
"[PATCH v2]" in the patch subject.

Please, resend this patch with the v2 label, and please provide
a change log in the patch notes, i.e. below the "---" line.

Here's an example of an earlier v2 patch submission [1] that you
may find helpful.

In the v2 submission, please feel free to also include my
