From 1f05c944e007809d7040a1cc87b16934fedd23f6 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 19 Mar 2014 18:31:10 -0700 Subject: [PATCH] drm/i915: Store the HW min frequency as min_freq this leaves a temporarily awkward min_delay (the soft limit) with the new min_freq (the hardware limit). It's fixed in the next patch.
