Subject: [PATCH v2 2/2] ARM: dts: qcom: Add support for Motorola Moto G (2013)
Message-ID: <8c605fb9cff8364ea6ac321b5a3fc265c5686def.1711454680.git.stano.jakubek@gmail.com>

Add a device tree for the Motorola Moto G (2013) smartphone based
on the Qualcomm MSM8226 SoC.

Initially supported features:
  - Buttons (Volume Down/Up, Power)
  - eMMC
  - Hall Effect Sensor
  - SimpleFB display
  - TMP108 temperature sensor
  - Vibrator

Note: the dhob and shob reserved-memory regions are seemingly a part of some
Motorola specific (firmware?) mechanism, see [1].

Changes in V2:
  - split hob-ram reserved-memory region into dhob and shob
  - add a note and a link to downstream documentation with more
    information about these regions
