From: Vishal Patel <[email protected]> The correct operating mode for the fan is inversed (1). The previous pwm driver implementation had a bug and the polarity information was propagated incorrectly to the kernel. The normal (0) polarity specified in the device tree was incorrectly clearing the polarity bit in the counter control register. After the bug fix, setting the polarity to inversed (1) in the device tree will clear the polarity bit.
