Neil Armstrong 2d481b2e3e pwm: Add driver for Amlogic Meson PWM controller ... This adds the driver for the PWM controller found in the Amlogic SoCs. This PWM is only a set of Gates, Dividers and Counters: PWM output is achieved by calculating a clock that permits calculating two periods (low and high). The counter then has to be set to switch after N cycles for the first half period. The hardware has no "polarity" setting. This driver reverses the period cycles (the low length is inverted with the high length) for PWM_POLARITY_INVERSED. Disabling the PWM stops the output immediately (without waiting for the current period to complete first). Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>		2020-10-05 18:02:16 +02:00
