From 58310c2ec9941ff4e2582764e8ab3ee9620ccd2c Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Fri, 14 Aug 2020 00:56:08 +0300 Subject: [PATCH] drm/panel: lvds: Read panel orientation The panel orientation needs to parsed from a device-tree and assigned to the panel's connector in order to make orientation property available to userspace. That's what this patch does for the generic LVDS panel.
