This patch series supports both PM8941 and PMI8998 WLED. The PMI8998 WLED has the support to handle the OVP (over voltage protection) and the SC (short circuit protection) interrupts. It also has the auto string detection algorithm support to configure the right strings if the user specified string configuration is in-correct. These three features are added in this series for PMI8998. changes from v1: - Fixed the commit message for - backlight: qcom-wled: Rename pm8941-wled.c to qcom-wled.c Changes from v2: - Fixed bjorn and other reviewer's comments - Seperated the device tree bindings - Splitted out the WLED4 changes in seperate patch - Merged OVP and auto string detection patch Changes from v3: - Added Reviewed-by/Acked-by tags - Fixed comments from Bjorn/Vinod/Rob - Splitting the "backlight: qcom-wled: Add support for WLED4 peripheral" patch to seperate the WLED3 specific restructure. Changes from v4: - Added reviewed-by/Acked-by tags - Fixed comments from Bjorn/Daniel/Pavel Changes from v5: - Fixed comments from Bjorn/Pavel Changes from v5/v6: - Fixed comments from Bjorn/Pavel on V5 series, which were missed in V6 series - Patch 1 and 2, mentioned below, from V6 series are picked by Pavel In next. Hence, dropped them in this series. https://lore.kernel.org/patchwork/patch/1132467/ https://lore.kernel.org/patchwork/patch/1132468/ Changes from v7: - Addressed comments from Daniel Thompson/Lee Jones - Patch 1 and 2, mentioned below, from V6 series are picked by Pavel In next.
