From 15ec959872b28007f567abe770426d0cbdc88c3b Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Tue, 25 Jul 2017 20:45:02 +0800 Subject: [PATCH 1/5] arm64: allwinner: a64: enable USB host controller for BPi M64 Banana Pi M64 connects the USB host-only controller on A64 SoC to a USB hub, which provided the two USB Type-A ports on the board. Enable the USB host controller. The OTG function of the Micro-USB port needs the drivevbus function of the AXP803 driver implemented, so it's not enabled now.
