The PWM Hi-Res allow configuring the PWM resolution from 8 bits PWM values up to 15 bits values. The current implementation loops through all possible resolutions (PWM sizes) on top of the already existing process of determining the prediv, exponent and refclk. The first issue is that the maximum value used for capping is wrongly hardcoded. The second issue is that it uses the wrong maximum possible PWM value for determining the best matched period. Fix both. Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> --- Changes in v2: - Re-worded the commit to drop the details that are not important w.r.t. what the patch is fixing. - Added another patch which fixes the resolution used for determining best matched period and PWM config. - Link to v1: https://lore.kernel.org/r/20250220-leds-qcom-lpg-fix-max-pwm-on-hi-res-v1-1-a161ec670ea5@xxxxxxxxxx --- Abel Vesa (2): leds: rgb: leds-qcom-lpg: Fix pwm resolution max for Hi-Res PWMs leds: rgb: leds-qcom-lpg: Fix calculation of best period Hi-Res PWMs drivers/leds/rgb/leds-qcom-lpg.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) --- base-commit: 8433c776e1eb1371f5cd40b5fd3a61f9c7b7f3ad change-id: 20250220-leds-qcom-lpg-fix-max-pwm-on-hi-res-067e8782a79b Best regards, -- Abel Vesa <abel.vesa@xxxxxxxxxx>
