| 2017-08-21 | pwm: bcm2835: Support for polarity setting via DT | Stefan Wahren | 1 | -0/+2 | |
| This adds support for the third (optional) pwm cell to specify the polarity, which is needed by display backlights for example. Signed-off-by: Stefan Wahren <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Signed-off-by: Thierry Reding <[email protected]> | |||||

| 2015-12-16 | pwm: bcm2835: Prevent division by zero | Stefan Wahren | 1 | -1/+9 | |
| It's possible that the PWM clock becomes an orphan. So better check the result of clk_get_rate() in order to prevent a division by zero. Signed-off-by: Stefan Wahren <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Signed-off-by: Thierry Reding <[email protected]> | |||||
| 2015-12-16 | pwm: bcm2835: Calculate scaler in ->config() | Stefan Wahren | 1 | -5/+3 | |
| Currently pwm-bcm2835 assumes a fixed clock rate and stores the resulting scaler in the driver structure. But with the upcoming PWM clock support for clk-bcm2835 the rate could change, so calculate the scaler in the ->config() callback.
