From 57075a472a5c2b9a7c498a9dc2f2cfcc1e898ec2 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 7 Sep 2016 14:25:21 +0800 Subject: sunxi: musb: Power off OTG port VBUS when disabled The Linux kernel musb driver expects VBUS to be off while initializing musb. Having it on results in a repeating string of warnings, followed by an unusable peripheral. The peripheral is only usable after physically removing the OTG adapter, letting musb reset its state.
