From 1c8491c3ab75cc54c5288552b3ffb8513a3488aa Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 15 Aug 2016 17:58:05 -0700 Subject: gru: Add USB 2.0 PHY tuning for Kevin This patch sets some magic number in magic undocumented registers that are rumored to make USB 2.0 signal integrity better on Kevin. I don't see any difference (unfortunately it doesn't solve the problems with long cables on my board), but I guess it doesn't hurt either way. BRANCH=None BUG=chrome-os-partner:56108,chrome-os-partner:54788 TEST=Booted Kevin with USB connected through Servo. Seems to have roughly the same failure rate as before.
