[PATCH 4.0 44/72] ASoC: rt5677: add register patch for PLL

From: Greg Kroah-Hartman
Date: Mon May 11 2015 - 14:52:16 EST

4.0-stable review patch. If anyone has any objections, please let me know.


From: Bard Liao <bardliao@xxxxxxxxxxx>

commit 74d6ea52aeef0236242221c6eff6d892565c5a92 upstream.

The PLL output will be unstable in some cases. We can fix it by
setting some registers.
