From e03826d5045e81a66a4fad7be9a8ecdaeb7911cf Mon Sep 17 00:00:00 2001 From: Keerthy Date: Tue, 17 Mar 2015 15:56:04 +0530 Subject: [PATCH] regulator: palmas: Correct TPS659038 register definition for REGEN2 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.
