This will result in PWM consumer requesting +duty cycle values higher than the allowed PWM value. + +For example, a consumer might request a period of 5ms while the best +(closest) period the PWM hardware will do is 4.26ms. For this best +matched resolution, if the selected resolution is 8-bit wide, when +the consumer asks for a duty cycle of 5ms, the PWM value will be 300, +which is outside of what the resolution allows. This will happen with +all possible resolutions when selected. + +Since for these Hi-Res PWMs, the current implementation is capping the PWM +value at a 15-bit resolution, even when lower resolutions are selected, +the value will be wrapped around by the HW internal logic to the selected +resolution. + +Fix the issue by capping the PWM value to the maximum value allowed by +the selected resolution. + +Cc: stable@vger.kernel.org # 6.4 +Fixes: b00d2ed37617 ("leds: rgb: leds-qcom-lpg: Add support for high resolution PWM") +Signed-off-by: Abel Vesa +Reviewed-by: Bjorn Andersson +Reviewed-by: Sebastian Reichel +Link: https://lore.kernel.org/r/20250305-leds-qcom-lpg-fix-max-pwm-on-hi-res-v4-2-bfe124a53a9f@linaro.org +Signed-off-by: Lee Jones +Signed-off-by: Greg Kroah-Hartman +--- + drivers/leds/rgb/leds-qcom-lpg.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/drivers/leds/rgb/leds-qcom-lpg.c ++++ b/drivers/leds/rgb/leds-qcom-lpg.c +@@ -529,7 +529,7 @@ static void lpg_calc_duty(struct lpg_cha + unsigned int clk_rate; + + if (chan->subtype == LPG_SUBTYPE_HI_RES_PWM) { +- max = LPG_RESOLUTION_15BIT - 1; ++ max = BIT(lpg_pwm_resolution_hi_res[chan->pwm_resolution_sel]) - 1; + clk_rate = lpg_clk_rates_hi_res[chan->clk_sel]; + } else { + max = LPG_RESOLUTION_9BIT - 1; diff --git a/queue-6.12/lib-scatterlist-fix-sg_split_phys-to-preserve-original-scatterlist-offsets.patch b/queue-6.12/lib-scatterlist-fix-sg_split_phys-to-preserve-original-scatterlist-offsets.patch new file mode 100644 index 0000000000..d921bdb250 --- /dev/null +++ b/queue-6.12/lib-scatterlist-fix-sg_split_phys-to-preserve-original-scatterlist-offsets.patch @@ -0,0 +1,56 @@ +From 8b46fdaea819a679da176b879e7b0674a1161a5e Mon Sep 17 00:00:00 2001 +From: T Pratham +Date: Wed, 19 Mar 2025 16:44:38 +0530 +Subject: lib: scatterlist: fix sg_split_phys to preserve original scatterlist offsets + +From: T Pratham + +commit 8b46fdaea819a679da176b879e7b0674a1161a5e upstream. + +The split_sg_phys function was incorrectly setting the offsets of all +scatterlist entries (except the first) to 0.
