From eb2217b4c25e3796b0e834ce6e4fb5490ee9ab27 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 5 Sep 2015 16:55:53 +0200 Subject: [PATCH] ARM: dts: sun5i: Add dts file for q8 formfactor a13 based tablets This commits adds a generic dts file for q8 formfactor a13 based tablets. The tablets ship in many variants, with the difference mainly being the touchscreen controller / accelerometer / wifi chip used. The wifi is USB based, and thus not listed in devicetree. The touchscreen controller / accelerometer may turn out to be a problem once we add support for those. We can either do something with devicetree overlays, or add sun5i-a13--.dts files. The latter is what the android mod community is doing with firmware images. This dts was tested with an a13 q8 tablet with a pcb labelled: "94V-0", silead gsl1680 touchscreen controller and a mc32x0 accelerometer.
