From 0cfa00cdb94d5349e0d33fabe157caef667ab004 Mon Sep 17 00:00:00 2001 From: Ran Wang Date: Tue, 26 Nov 2019 11:40:40 +0800 Subject: armv8: Add workaround for USB erratum A-050106 USB3.0 Receiver needs to enable fixed equalization for each of PHY instances in an SOC. This is similar to erratum A-009007, but this one is for LX2160A, and the register value is different.
