This patch series has the following two WLED fixes 1. As per the current implementation, for WLED5, after the FSC (Full Scale Current) update the driver is incorrectly toggling the MOD_SYNC register instead of toggling the SYNC register. The patch 1/2 fixes this by toggling the SYNC register after FSC update.
2. Currently, the sync bits are transitioned from set-then-clear after FSC and brightness update. As per hardware team recommendation the FSC and brightness sync takes place from clear-then-set transition of the sync bits. The patch 2/2 fies this issue.
Changes from V2: 1. Added Daniel's "Reviewed-by" tag for patch 1/2. 2. Updated the patch 2/2 description with "set" and "clear" terminology instead of "1" and "0". 3. Updated the cover letter with "set" and "clear" terminology instead of "1" and "0".
Changes from V1: 1. Updated the cover letter. 2. Updated the description of the patches as per Daniel's suggestion.
