2023-12-20pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()Sean Young1-2/+2
In order to introduce a pwm api which can be used from atomic context, we will need two functions for applying pwm changes: int pwm_apply_might_sleep(struct pwm *, struct pwm_state *); int pwm_apply_atomic(struct pwm *, struct pwm_state *); This commit just deals with renaming pwm_apply_state(), a following commit will introduce the pwm_apply_atomic() function.

2023-04-20leds: pwm-multicolor: Simplify an error messageChristophe JAILLET1-2/+2
dev_err_probe() already display the error code. There is no need to duplicate it explicitly in the error message. While at it, add a missing \n at the end of the message.

2022-07-17leds: pwm-multicolor: Support active-low LEDsEmil Renner Berthing1-0/+5
Add support for LEDs wired up to light when the PWM output is low, just like the regular PWM LEDs. Signed-off-by: Emil Renner Berthing <emil.renner.berthing@canonical.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Pavel Machek <pavel@ucw.cz>
2022-07-17leds: pwm-multicolor: Don't show -EPROBE_DEFER as errorsEmil Renner Berthing1-2/+1
When requesting a PWM it might return -EPROBE_DEFER if it hasn't probed yet. This is not an error, so just propagate the -EPROBE_DEFER without logging anything. There is already dev_err_probe for exactly this situation.

2022-05-08leds: Move pwm-multicolor driver into rgb directorySven Schwermer1-0/+186
The drivers/leds/rgb subdirectory is relatively fresh, so we move this new PWM multi-color driver into it. Signed-off-by: Sven Schwermer <sven.schwermer@disruptive-technologies.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>
