From d1e082ffb898bd9cf7cb58358917a415d2dd0a13 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Fri, 1 Apr 2016 16:02:33 +0300 Subject: [PATCH] drm/i915/bxt: Fix GRC code register field definitions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This has been corrected in BSpec quite some time ago, but we missed it somehow. The wrong field definitions resulted in configuring PHY0 with an incorrect GRC value. v2: - Remove the FIXME comment, we left in the code exactly about this issue.
