From: Philipp Zabel Date: Thu, 11 Dec 2014 17:32:46 +0000 (+0100) Subject: drm/panel: Add display timing for HannStar HSD070PWW1 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab07725abc9aa1e3dbc41ee429ad19336b31f207;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git 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.
