From d435a2af12349e6285559196675ad45f1e4a041d Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 19 Nov 2014 10:29:55 +0100 Subject: [PATCH] drm/panel: simple: Add support for Giantplus GPG482739QS5 This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD panel to the simple-panel driver. This panel is connected via a parallel bus and uses both HSYNC and VSYNC, whose lengths are unfortunately not clearly defined. The datasheet only specifies the front- and backporch length, but the timing diagram suggests that both sync signals should be asserted for exactly one clock cycle.
