[PATCH V3 0/2] Fix WLED FSC Sync and brightness Sync settings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
