From c7670b1098b1a05c5266a7d3d2f07165621e7de9 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Sat, 2 Nov 2013 21:07:37 -0700 Subject: [PATCH] drm/i915/bdw: on Broadwell, the panel fitter is on the pipe MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit So you can use the panel fitter while the power well is disabled and you also don't need to set the "pipe" bit. v2: Rebased on top of Jesse's pfit refactor, which moved pfit state into the pipe_config. v3: Rebase on top of the latest Haswell/panel fitter rework, which neatly resolves a FIXME we have in this patch here: v4: Rebase on top of the new power domain framework.
