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 set-then-cleared 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.
