Some appliances of ktd2692 don't have the AUX pin connected to a GPIO. Specifically, Samsung Galaxy J5 (2015), which uses ktd2692 for driving the front flash LED, has the pin not connected anywhere on schematics. Make specifying the AUX pin optional, since it is additional functionality and only affects amount of current going through the LED. Also convert the txt device-tree bindings to yaml and pick up maintenance over the yaml binding and the driver itself. v2: - fix the dt_binding_check v3: - set the aux_gpio to NULL to avoid passing ERR_PTR as a gpio v4: - maintainership -> maintenance (description) - remove the if (led->aux_gpio) - use devm_gpiod_get_optional for aux gpio v5: - use ret to pass a correct error return code (Christophe) v6: - use PTR_ERR properly (when IS_ERR is true) (Christophe) Markuss Broks (2): dt-bindings: leds: convert ktd2692 bindings to yaml leds: ktd2692: Make aux-gpios optional .../bindings/leds/kinetic,ktd2692.yaml | 87 +++++++++++++++++++ .../devicetree/bindings/leds/leds-ktd2692.txt | 50 ----------- MAINTAINERS | 6 ++ drivers/leds/flash/leds-ktd2692.c | 18 ++-- 4 files changed, 103 insertions(+), 58 deletions(-) create mode 100644 Documentation/devicetree/bindings/leds/kinetic,ktd2692.yaml delete mode 100644 Documentation/devicetree/bindings/leds/leds-ktd2692.txt -- 2.35.1
