From 880e1509db9732d5696d2a092e9bd61d80ad00be Mon Sep 17 00:00:00 2001 From: Maciej S. Szmigiero Date: Sat, 16 Apr 2016 00:27:23 +0200 Subject: ARM: dts: imx6qdl-udoo: add 7 inch LCD touchscreen panel support The official UDOO board kit has 7 and 15.6 inch touchscreen LCD panels as options. This patch adds support for 7 inch panel only, but the 15.6 inch one should be easy to add using the same regulator, backlight device and LVDS channel. Since this panel is an option for UDOO board it is disabled by default and can be enabled (for example) by the following U-Boot commands: fdt set backlight status okay fdt set panelchan status okay fdt set panel7 status okay fdt set touchscreenp7 status okay The LVDS channels is also disabled by default to avoid warning from its driver.
