From 5c24c05efa4800bbe42de0ad3e752c5fd75fa351 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 19 Oct 2017 09:44:14 +0200 Subject: [PATCH] platform/x86: silead_dmi: Fix GP-electronic T701 entry The GP-electronic T701 has its LCD panel mounted upside-down, initially my plan was to fix this by transparently rotating the image in the i915 driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but that approach has been rejected instead the kernel will now export a "panel orientation" property on the drm-connector for the panel and let userspace deal with it. But userspace expects the touchscreen coordinates to match the panel coordinates *before* applying any rotation, so now that we no longer hide the upside-down-ness of the LCD panel from userspace the coordinates being generated are wrong and we need to apply a rotation of 180 degrees to the coordinates to fix this.
