From a853205efb741951382edfdb1efa36886eeb90c3 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 23 Oct 2014 16:31:06 +0200 Subject: [PATCH] drm/panel: simple: Add HannStar HSD070PWW1 7.0" WXGA TFT LCD panel This patch adds support for the HannStar Display Corp. HSD070PWW1 7.0" WXGA TFT LCD panel to the simple-panel driver. The binding documentation is included. This panel is connected via LVDS and uses the data enable signal for timing. Since HSYNC/VSYNC are ignored, the split between sync length and porches is arbitrary, as long as the complete horizontal blanking interval is 160 clocks, and the vertical blanking interval is 23 lines.
