From 9bfe7c8d1af5a8a55a21b5407e1a35ed3c1b98eb Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 16 Nov 2016 14:15:08 +0100 Subject: ARM: dts: sun5i: Add touchscreen node to reference-design-tablet.dtsi Just like on sun8i all sun5i tablets use the same interrupt and power gpios for their touchscreens. I've checked all known a13 fex files and only the UTOO P66 uses a different gpio for the interrupt. Add a touchscreen node to sun5i-reference-design-tablet.dtsi, which fills in the necessary gpios to avoid duplication in the tablet dts files, just like we do in sun8i-reference-design-tablet.dtsi. This will make future patches adding touchscreen nodes to a13 tablets simpler.
