Hi Russell
Maybe split the PWM parts from the cooling maps? I don't see any
reason not to merge the PWM parts.
Maybe sometime later I might take a closer look at the maps. I have a
wrt1900ac, which is Armada XP based. It has a fan on a GPIO pin. I
currently have a userspace daemon controlling the fan based on hwmon
device data. Getting the kernel to do it all would be nice.
