From 4afeb8d87bcd6eed75aafb3b8e3b93b3ce611d06 Mon Sep 17 00:00:00 2001 From: Fugang Duan Date: Mon, 26 Oct 2015 14:07:55 +0800 Subject: [PATCH] MLK-11758 dts: mx6ul evk: set regulator wlreg_on always on Murata adapter VDDIO is derived from sd slot VMMC supply, if usdhc cannot detect sd/sdio card, VMMC is shutdown that causes VDDIO has no voltage, and bt cannot work. So BT depends on VDDIO/VMMC. Now the workaround is set wlreg_on alwasys on, usdhc can detect wifi card and supply VMMC 3.3V voltage, so that Murata adapter VDDIO has power supply.
