[PATCH 0/2] Add initial device tree for Motorola Moto G (2014)

[David Wales via B4 Relay]

The Motorola Moto G (2014) is the second device in the Moto G series,
with codename motorola-titan.

This series documents the motorola-titan, and adds an initial device
tree.

These patches have been previously discussed and merged into the
downstream msm8226-mainline fork:

[PATCH 2/2] ARM: dts: qcom: Support Motorola Moto G2 (2014)

[David Wales via B4 Relay]

From: David Wales <daviewales@disroot.org>

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. [1]

This line will keep these regulators always-enabled, until (which
may perhaps never happen) the driver takes over, it should be
unnecessary

otherwise lgtm
