From 88651aebd276f272f34f2459d1eb2a86413aaabc Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 30 May 2015 16:55:06 +0200 Subject: [PATCH] ARM: sun8i: dts: Add Ippo-q8h v1.2 with A33 The Ippo-q8h is a tablet circuit board commonly found in cheap Android tablets. The v1.2 version can be used with either an A23 or A33 SoC. This version features 512 MB DRAM, 4G NAND, MMC, LCD, capacitive touchscreen, accelerometer, 2 camera sensors, USB OTG, microphone and speakers. i2c0 is connected to the gsl1680 capacitive touch panel controller, i2c1 is connected to an mma7660 3-axis accelerometer, these peripherals are not supported by the kernel yet, i2c bus functionality has been tested via i2c-dev.
