From cff94887d55a32bf8f7095482d9ba92784280a5c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 15 May 2017 09:50:34 +0200 Subject: ARM: dts: add core I2C devices to the APQ8060 Dragonboard The APQ8060 Dragonboard has an Atmel AT24c128 EEPROM and a Wolfson Micro WM8903 codec connected to its GSBI8 I2C bus. Add entries for these to the device tree. The interrupt line from the WM8903 chip is not routed anywhere on this design so it can not be used.
