From 47e2843f5e2e1cdcf25fdfa28173ae5315e6497b Mon Sep 17 00:00:00 2001 From: John Stultz Date: Sat, 4 Jul 2020 04:31:51 +0000 Subject: dts: hi3660: Add support for basic usb gadget on Hikey960 This patch adds basic core dwc3, usb phy and rt1711h nodes for usb support on Hikey960. This does not enable the mux/hub functionality on the board, so the USB-A host ports will not function, but does allow the USB-C port to function in gadget mode (unfortunately not in host, as the hub/mux functionality is needed to enable vbus output to power devices in host mode). This is based on an old patch originally by Yu Chen.
