From 58d4d32f431a560baff5fbb6deae8ad324552dde Mon Sep 17 00:00:00 2001 From: Ramalingam C Date: Wed, 3 Feb 2016 18:20:46 +0530 Subject: [PATCH] drm/i915/dsi: Configure DSI after enabling DSI pll We need to enable DSI PLL before configuring the DSI registers. This has worked before on BYT/CHV, but BXT is more fussy.
