leds: Drop duplicate LEDS_EXPRESSWIRE config

2025-11-06T16:57:59+00:00

While moving said config symbol out of the "if NEW_LEDS" block, I accidentally left a copy inside that block. Remove it.

leds: lp55xx_common: Enable use without FW_LOADER_USER_HELPER

2025-10-21T09:46:30+00:00

Many distributions disable FW_LOADER_USER_HELPER, and this configuration makes lp55xx LEDs completely unusable. Enable their use by only implying the user helper, since the basic LEDs and the hardware patterns can be used with only the sysfs interface. Tested on Nokia N900 with LP5523. Additionally do not refer to the sysfs interface as legacy anymore, since it might be the only one available to users. Signed-off-by: Sicelo A. Mhlongo Signed-off-by: Lee Jones

leds: Do not enable by default during compile testing

Enabling the compile test should not cause automatic enabling of all drivers, but only allow to choose to compile them. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250417074656.81626-1-krzysztof.kozlowski@linaro.org Signed-off-by: Lee Jones

Pull LED updates from Lee Jones: - pca955x: Add HW blink support, utilizing PWM0. It supports one frequency across all blinking LEDs and falls back to software blink if different frequencies are requested. - trigger: netdev: Allow configuring LED blink interval via .blink_set even when HW offload (.hw_control) is enabled. - led-core: Fix a race condition where a quick LED_OFF followed by another brightness set could leave the LED off incorrectly, especially noticeable after the introduction of the ordered workqueue. - qcom-lpg: Add support for 6-bit PWM resolution alongside the existing 9-bit support. - qcom-lpg: Fix PWM value capping to respect the selected resolution (6-bit or 9-bit) for normal PWMs. - qcom-lpg: Fix PWM value capping to respect the selected resolution for Hi-Res PWMs. - qcom-lpg: Fix calculation of the best period for Hi-Res PWMs to prevent requested duty cycles from exceeding the maximum allowed by the selected resolution. - st1202: Add a check for the error code returned by devm_mutex_init(). - pwm-multicolor: Add a check for the return value of fwnode_property_read_u32(). - st1202: Ensure hardware initialization (st1202_setup) happens before DT node processing (st1202_dt_init). - Kconfig: leds-st1202: Add select LEDS_TRIGGER_PATTERN as it's required by the driver. - lp8860: Drop unneeded explicit assignment to REGCACHE_NONE. - pca955x: Refactor code with helper functions and rename some functions/variables for clarity. - pca955x: Pass driver data pointers instead of the I2C client to helper functions. - pca955x: Optimize probe LED selection logic to reduce I2C operations. - pca955x: Revert the removal of pca95xx_num_led_regs() (renaming it to pca955x_num_led_regs) as it's needed for HW blink support. - st1202: Refactor st1202_led_set() to use the !! operator for boolean conversion. - st1202: Minor spacing and proofreading edits in comments. - Directory Rename: Rename the drivers/leds/simple directory to drivers/leds/simatic as the drivers within are not simple. - mlxcpld: Remove unused include of acpi.h. - nic78bx: Tidy up the ACPI ID table (remove ACPI_PTR, use mod_devicetable.h, remove explicit driver_data initializer). - tlc591xx: Convert text binding to YAML format, add child node constraints, and fix typos/formatting in the example. - qcom-lpg: Document the qcom,pm8937-pwm compatible string as a fallback for qcom,pm8916-pwm. * tag 'leds-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds: (23 commits) leds: nic78bx: Tidy up ACPI ID table leds: mlxcpld: Remove unused ACPI header inclusion leds: rgb: leds-qcom-lpg: Fix calculation of best period Hi-Res PWMs leds: rgb: leds-qcom-lpg: Fix pwm resolution max for Hi-Res PWMs leds: rgb: leds-qcom-lpg: Fix pwm resolution max for normal PWMs leds: Rename simple directory to simatic leds: Kconfig: leds-st1202: Add select for required LEDS_TRIGGER_PATTERN leds: leds-st1202: Spacing and proofreading editing leds: leds-st1202: Initialize hardware before DT node child operations leds: pwm-multicolor: Add check for fwnode_property_read_u32 leds: rgb: leds-qcom-lpg: Add support for 6-bit PWM resolution leds: Fix LED_OFF brightness race Revert "leds-pca955x: Remove the unused function pca95xx_num_led_regs()" leds: st1202: Refactor st1202_led_set() to use !! operator for boolean conversion dt-bindings: leds: qcom-lpg: Document PM8937 PWM compatible leds: pca955x: Add HW blink support leds: pca955x: Optimize probe LED selection leds: pca955x: Use pointers to driver data rather than I2C client leds: pca955x: Refactor with helper functions and renaming dt-bindings: leds: Convert leds-tlc591xx.txt to yaml format ...

Tidy up ACPI ID table: - Drop ACPI_PTR() and hence replace acpi.h with mod_devicetable.h and other necessary headers - Remove explicit driver_data initializer - Drop comma in the terminator entry With that done, extend compile test coverage.

leds: Kconfig: leds-st1202: Add select for required LEDS_TRIGGER_PATTERN

2025-03-13T15:28:27+00:00

leds-st1202 requires the LED Pattern Trigger (LEDS_TRIGGER_PATTERN), which is not selected when LED Trigger support is (LEDS_TRIGGERS). To reproduce this: - make menuconfig KCONFIG_CONFIG= - select LEDS_ST1202 dependencies OF, I2C and LEDS_CLASS. - select LEDS_ST1202 - LEDS_TRIGGERS is selected but LEDS_TRIGGER_PATTERN isn't. The absence of LEDS_TRIGGER_PATTERN explicitly required can lead to builds in which LEDS_ST1202 is selected while LEDS_TRIGGER_PATTERN isn't. The direct result of that would be that /sys/class/leds//hw_pattern wouldn't be available and there would be no way of interacting with the driver and hardware from user space. Add select LEDS_TRIGGER_PATTERN to Kconfig to meet the requirement and indirectly document it as well.
