From 469d4b2a4ed7a255ffef31fad9d56bb6f7ac1213 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 31 Mar 2015 14:11:59 +0300 Subject: [PATCH] drm/i915: Simplify ilk_get_aux_clock_divider MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that we are "extracting" the cdclk frequency on ILK-IVB we can also simplify ilk_get_aux_clock_divider() to calculate the divider based on cdclk instead of hardcoding the values.
