The default of_pwm_simple_xlate() function is capable to process PWM inverted signal polarity flag, there is no need to use exported of_pwm_xlate_with_flags() by the drivers.
The minimal expected by of_pwm_simple_xlate() amount of pwms arguments is changed from 3 to 2, it allows to specify less PWM arguments in the device tree omitting secondary configuration options (in this case it is signal polarity value). The change has side effects, only if Signed-off-by: Vladimir Zapolskiy <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Lothar Waßmann <[email protected]> Cc: Sascha Hauer <[email protected]> Cc: Heiko Stuebner <[email protected]> Cc: Tony Prisk <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] --- drivers/pwm/pwm-atmel-hlcdc.c | 2 -- drivers/pwm/pwm-atmel-tcb.c | 2 -- drivers/pwm/pwm-atmel.c | 6 ------ drivers/pwm/pwm-bcm-kona.c | 2 -- drivers/pwm/pwm-fsl-ftm.c | 2 -- drivers/pwm/pwm-renesas-tpu.c | 2 -- drivers/pwm/pwm-rockchip.c | 5 ----- drivers/pwm/pwm-samsung.c | 3 --- drivers/pwm/pwm-tiecap.c | 2 -- drivers/pwm/pwm-tiehrpwm.c | 2 -- drivers/pwm/pwm-vt8500.c | 2 -- 11 files changed, 30 deletions(-) diff --git a/drivers/pwm/pwm-atmel-hlcdc.c b/drivers/pwm/pwm-atmel-hlcdc.c index eaf8b12..492a1b5 100644 --- a/drivers/pwm/pwm-atmel-hlcdc.c +++ b/drivers/pwm/pwm-atmel-hlcdc.c @@ -209,8 +209,6 @@ static int atmel_hlcdc_pwm_probe(struct platform_device *pdev) chip->chip.dev = dev;
