Date: Sun, 1 Jul 2018 22:18:27 -0300 From: Fabio Estevam <festevam@...il.com> To: broonie@...nel.org Cc: shawnguo@...nel.org, anson.huang@....com, linux-kernel@...r.kernel.org, Fabio Estevam <fabio.estevam@....com> Subject: [PATCH] regulator: Revert "regulator: pfuze100: add enable/disable for switch" From: Fabio Estevam <fabio.estevam@....com> This reverts commit 5fe156f1cab4f340ddb6283c993912be77594016. Commit 5fe156f1cab4 ("regulator: pfuze100: add enable/disable for switch") causes boot regression on some platforms such as imx6sl-evk and imx6sll-evk. After this commit the SW4 regulator will be turned off and since it supplies the DDR voltage on these boards, a kernel hang is observed. Revert it to avoid breaking old dtb's.
