[PATCH v2 2/2] ARM: dts: qcom: Add support for Motorola Moto G (2013)

From: Stanislav Jakubek
Date: Tue Mar 26 2024 - 08:12:35 EST

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].

Signed-off-by: Stanislav Jakubek <stano.jakubek@xxxxxxxxx>
---
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
