From 706e6b4cd46aea01d0fbb1f5ba2c19a5f5e035a7 Mon Sep 17 00:00:00 2001 From: Ranjani Vaidyanathan Date: Tue, 4 Mar 2014 15:06:30 -0600 Subject: ENGR00299939-1 ARM: dts: imx6sl:Add dummy LDO2p5 regulator to support vbus wakeup LDO2p5 cannot be disabled in low power idle mode when the USB driver enables VBUS wakeup. To identify when LDO2p5 can be disabled add a dummy regulator that the USB driver will enable when VBUS wakeup is required. This patch adds the dummy regulator to the dts files.
