Signed-off-by: Alexander Stein --- Changes in v2: * Adjust commit subject to match the board name Now with inverted polarity support for pwm-fan in place, add PWM fan DT nodes for TQMa8MPQL + MBa8MPxL. As this is optional, it's disabled by default. This is based on next-20221018. Note: This device needs 'pwm1_enable' set to 3.
