From 89423f6abf6d6a5046cdd7779661726ba83b796f Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Wed, 19 Feb 2020 01:22:00 +0100 Subject: [PATCH] ipq806x: add patch to fix broken usb3 Due to changes in syscon driver, the phy dwc3 driver needs to use device_node_to_regmap since it has to skip the new introduced clk check. This fix broken usb3 on this target.
