From b67379a6ac02f25a5b4ae940e3479e442aa19111 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 24 Nov 2016 19:29:08 +0800 Subject: ARM: dts: sun6i: hummingbird: Enable USB OTG The A31 Hummingbird has a mini USB OTG port, and uses GPIO pins from the SoC for ID pin and VBUS detection and VBUS control. The PMIC can also do VBUS detection and control. Here we prefer to use the PMIC's DRIVEVBUS function to control VBUS for USB OTG, as that is the hardware default.
