From: David Wales <redacted> Add device tree for Motorola Moto G2 (2014) (motorola-titan) smartphone based on the Qualcomm MSM8226 SoC. Initially supported features: - Buttons (Volume Down/Up, Power) - eMMC - Hall Effect Sensor - Simple framebuffer display - Vibrator Based on device tree for similar device msm8226-motorola-falcon. Initial commit for falcon notes that dhob and shob reserved-memory regions seem to be related to a Motorola specific mechanism.
