Date: Fri Apr 10 2015 - 09:26:50 EST


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

------------------

From: Keerthy <j-keerthy@xxxxxx>

commit e03826d5045e81a66a4fad7be9a8ecdaeb7911cf upstream.

The register offset for REGEN2_CTRL in different for TPS659038 chip as when
compared with other Palmas family PMICs. In the case of TPS659038 the wrong
offset pointed to PLLEN_CTRL and was causing a hang. Correcting the same.
