Hi, This patch series adds DT bindings (patch #1) and the corresponding driver (patch #2) for the Panasonic AN30259A 3-channel LED driver. AN30259A uses an internal clock for controlling brightness/on-off cycles, but also supports using an external PWM/clock input. This patch series only implements support for the former. The AN30259A is connected using I2C, and the datasheet is freely available[0]. Changes since v2: * Drop "an30259a:" prefix from bindings and add it in the device driver instead. * Use led-controller instead of leds for sample DT binding. * Use ":indicator" instead of ":notification" in sample DT binding. * Merge an30259a_led_set and an30259a_brightness to an30259a_brightness_set (and same for blink functions). * Explain the range limitations of the AN30259A's sloping mode in the code - the AN30259A only has a 7-bit PWM range in slope mode, and the bottom 3 bits are always set. Changes since v1: * Documentation formatting/grammar fixes. * Use reg property instead of led-sources for leds. * Add default-state support. * Fix auto-probing when built as a module. * Simplified DT parsing code. * Use devm version of led_class_register(). * Fix LED naming scheme. * Fixed checkpatch --strict issues. I've kept Rob's Reviewed-By and Pavel's ack on the DT patch since the changes to the binding are minor and inline with other LED DT binding documentation.
