From ac7f11c6106507f1e09a970a03904c323ae741b8 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Tue, 8 Mar 2016 17:46:19 +0200 Subject: [PATCH] drm/i915: Move shared dpll struct definitions to separate header file Move the declarations related to shared dplls from i915_drv.h to their own header file. The code that became the shared dpll infrastructre was first introcude in commit ee7b9f93fd96 ("drm/i915: manage PCH PLLs separately from pipes"), hence the 2012-2016 copyright years in the new header file.
