From 7b22b8c402c8ee26dd4dc1474887a2a91961e766 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Fri, 2 Jun 2017 13:06:39 -0700 Subject: [PATCH] drm/i915/cnp: Introduce Cannonpoint PCH. Most of south engine display that is in PCH is still the same as SPT and KBP, except for this key differences: - Backlight: Backlight programming changed in CNP PCH. - Panel Power: Sligh programming changed in CNP PCH. - GMBUS and GPIO: The pin mapping has changed in CNP PCH. All of these changes follow more the BXT style. v2: Update definition to use dev_priv isntead of dev (Tvrtko).
