In certain PMICs, LUT pattern and LPG configuration is stored in SDAM
modules instead of LUT peripheral. This feature is called PPG.

Hi Lee,

Just wanted to get some quick clarification. Would you like checkpatch.pl issues fixed in a new version
of this series or would you like a new patch to fix all the issues? Looks like these patches are in your
for-leds-next-next branch so I am guessing you would like a new follow up patch
but I just wanted to double check.

Thanks,
Anjelique
