From 7fe2ebf3a326026b9ab80ed94da3cd217c84724d Mon Sep 17 00:00:00 2001 From: "Arnaud Patard (Rtp)" Date: Fri, 5 Mar 2021 11:27:46 +0100 Subject: [PATCH] rockchip: video: vop: Use endpoint compatible string to find VOP mode The current code is using an hard coded enum and the of node reg value of endpoint to find out if the endpoint is mipi/hdmi/lvds/edp/dp. The order is different between rk3288, rk3399 vop little, rk3399 vop big. A possible solution would be to make sure that the rk3288.dtsi and rk3399.dtsi files have "expected" reg value or an other solution is to find the kind of endpoint by comparing the endpoint compatible value. This patch is implementing the more flexible second solution.
