From 723ca929a507a05bf4638f620b284f25d2047cf3 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Sat, 10 Jun 2017 00:05:48 +0800 Subject: [PATCH] ARM: sun6i: a31s: primo81: Change USB OTG to OTG mode Now that we have support for the AXP221 PMIC's USB VBUS detection and DRIVEVBUS vbus control, we can use the USB OTG port in proper OTG mode. This patch enables the aforementioned PMIC functions, adds the OTG ID detection pin to the USB PHY node, and changes the mode of USB OTG to "otg".
