From 97e21d3e956ea2657a63fb98c22548f9fd52afef Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Mon, 28 Dec 2020 00:49:33 +0100 Subject: nb/intel/hsw,soc/intel/{bdw,skl,apl},mb/*: unify dt panel settings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are multiple different devicetree setting formats for graphics panel settings present in coreboot. Replace the ones for the platforms that already have (mostly) unified gma/graphics setup code by a unified struct in the gma driver. Hook it up in HSW, BDW, SKL, and APL and adapt the devicetrees accordingly. Always ensure that values don't overflow by applying appropriate masks. The remaining platforms implementing panel settings (GM45, i945, ILK and SNB) can be migrated later after unifying their gma/graphics setup code.
