From 6745a2ceaac6d4dd3ddac460dc149275b0ae7fc0 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Sat, 2 Nov 2013 21:07:34 -0700 Subject: [PATCH] drm/i915/bdw: Broadwell also has the "power down well" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Just like Haswell, but with the small twist that the panel fitter for pipe A is now also in the always-on power well. v2: Use the new HAS_POWER_WELL macro. v3: Rebase on top of intel_using_power_well patches. v4: This time actually update the PFIT check correctly so that the pipe A pfit is in the always-on domain. v5: Rebase on top of the VGA power domain addition. v6: Rebase on top of the new power domain infrastructure. Also pimp the commit message a bit while at it. v7: Use IS_BROADWELL instead of IS_GEN8 (Ville).
