From ae409cc7c3cdb9ac4a1dba3eae70efec3d6b6c79 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Thu, 4 Oct 2018 20:28:48 +0800 Subject: [PATCH] phy: sun4i-usb: add support for H6 USB2 PHY The USB 2.0 PHY on Allwinner H6 SoC is similar to older Allwinner SoCs, with some USB0 quirk like A83T and PHY index 1/2 missing. Add support for it.
