From 2ce147f36dc5a1f3b49abd8ce3164ad0f04ec863 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Sat, 28 Jun 2014 02:04:13 +0300 Subject: [PATCH] drm/i915: Add chv port D TX wells MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add the TX wells for port D. The Punit subsystem numbers are a total guess at this time. Also I'm not sure these even exist. Certainly the Punit in current hardware doesn't deal with these.
