From 56b7b1aa13b971e50402a63c37aaf244644b4f8a Mon Sep 17 00:00:00 2001 From: Madhav Chauhan Date: Thu, 29 Nov 2018 16:12:31 +0200 Subject: [PATCH] drm/i915/icl: Define display GPIO pins for DSI Display Pins are the only GPIOs that need to be used by driver for DSI panels. So driver should now have its own implementation to toggle these pins based on GPIO info received from VBT sequences.
