From ab07725abc9aa1e3dbc41ee429ad19336b31f207 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 11 Dec 2014 18:32:46 +0100 Subject: [PATCH] drm/panel: Add display timing for HannStar HSD070PWW1 The HannStar HSD070PWW1 LVDS panel data sheet lists allowed ranges additionally to the typical values for pixel clock rate (64.3-82 MHz) and blanking intervals (54-681 clock cycles horizontally, 3-23 lines vertically). This patch replaces this panel's display mode with the display timing information to describe acceptable timings. Since the HSYNC and VSYNC are unused, the distribution between front porches, back porches, and sync pulse lengths was chosen at will.
