Re: [PATCH V5 2/2] backlight: qcom-wled: Correct the sync_toggle sequence

On Thu, 18 Mar 2021, Kiran Gunda wrote:

As per the current implementation, after FSC (Full Scale Current) and brightness update the sync bits are set-then-cleared. But, the FSC and brightness sync takes place when the sync bits are set (e.g. on a rising edge). So the hardware team recommends a clear-then-set approach in order to guarantee such a transition regardless of the previous register state.
