From: Ander Conselvan de Oliveira Date: Fri, 23 Oct 2015 10:01:46 +0000 (+0300) Subject: drm/i915 Call get_adjust_train() from clock recovery and channel eq X-Git-Tag: MMI-PSA29.97-13-9~7427^2~45^2~1223 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c1a5e9f69a4048e9127f5e8b2887bc89c435f9a3;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git drm/i915 Call get_adjust_train() from clock recovery and channel eq Move the call to intel_dp_get_adjust_train() out of intel_dp_update_link_train() and call it instead from the clock recovery and channel equalization features. A follow up patch will remove the DP register write from that function, so that it handles only the DPCD write.
