Make these configurable via DT. Besides addressing review comments v3 folds in the patches to disable the chip and turn of the regulator on brightness 0 from https://lore.kernel.org/linux-leds/20191226101419.GE4033@amd/T/#t Besides addressing review comments v2 also allows to limit the maximum led current. Patches are against next-20191220. Changes from v2 - As per review comment from Pavel Machek https://lore.kernel.org/linux-leds/20191226100615.GA4033@amd/T/#u - Use default value in DT example https://lore.kernel.org/linux-leds/20191226100842.GC4033@amd/T/#u - Use uppercase LED in commit message https://lore.kernel.org/linux-leds/20191226101336.GD4033@amd/T/#u - Fix typo in commit message - Use correct return value when checking if property is present - Fold in https://lore.kernel.org/linux-leds/20191226101419.GE4033@amd/T/#t - Add Acked-By's from Pavel Machek, thanks!
