From da4e1d780656d6a733f7c2445697466c86a8e901 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Wed, 4 May 2022 17:08:11 +0200 Subject: soc/intel/tigerlake: Add enum for `DdiPortXConfig` Add an enum for `DdiPortXConfig` devicetree options. Note that setting these options to zero does not disable the corresponding DDI port, but instead indicates that no LFP (Local Flat Panel, i.e. internal LCD) is connected to it.
