From 9d6c9d988f0cd2fae095f1c76dc6b786a890108b Mon Sep 17 00:00:00 2001 From: Amit Singh Tomar Date: Fri, 21 Oct 2016 02:24:30 +0100 Subject: [PATCH] sunxi: A64: enable USB support Mostly by adding MACH_SUN50I to some existing #ifdefs enable support for the the HCI0 USB host controller on the A64. Fix up some minor 64-bit hiccups on the way. Add the bare minimum DT bits to the A64 .dtsi and enable the controllers and the PHY on the Pine64. This is limited to the first USB controller at the moment, which is connected to the lower USB socket on the Pine64 board.
