From ec2f343e720eca5ec7015b4d2b5fc2703604835e Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 14 Nov 2017 11:47:53 -0800 Subject: [PATCH] drm/i915/cnl: Remove spurious central_freq. "Display software must leave this field at the default value. It no longer needs to be configured as part of PLL programming." We respect this already and we are setting up the default one line below: "DPLL_CFGCR1_CENTRAL_FREQ". Also we don't touch anywhere else this central_freq for cnl. So let's remove from the final write. No functional change. Only a clean-up patch.
