From acad889f9eb86ba8830de33cc7a391e9f68ca5ea Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Tue, 8 Mar 2016 21:00:56 +0200 Subject: [PATCH] drm/i915/bxt: add missing DSI power domain to power well 1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The DSI power domain was missing from BXT power well 1 definitions, failing to get the power well for DSI transcoders. As pipe A is in the same power well as DSI transcoders, the problem should only occur with pipes B and C. According to Ville, this is basically a nop since pw1 is under dmc control. But given that we still have this stuff defined here, it's clearly correct to include DSI here.
