[PATCH v4 0/2] ARM: dts: qcom: msm8926-sony-xperia-yukon-eagle: add initial device tree

[Erikas Bitovtas]

Sony Xperia M2 is a smartphone released in 2014 based on the Qualcomm
Snapdragon 400 (MSM8926) platform.

Add initial device tree for Sony Xperia M2 with support for:
- Framebuffer
- GPIO buttons (Volume Down and Camera)
- Regulators
- Internal storage
- SD card
- Accelerometer
- Ambient Light/Proximity sensor
- NFC
- pm8226_resin (Volume Up)
- Vibrator
- USB/Charger

Changes in v4:
- Defined pinctrl for GPIO buttons.
- Aligned quotation marks in mount-matrix for the accelerator.
- Dropped magnetometer from the patch. It probes, but fails to read its
  revision if reset GPIO is not defined, and this model does not have a
  reset GPIO. Nevertheless, even if one is defined, the probe fails with
  a timeout. Needs further investigation.
- Link to v3: https://patch.msgid.link/20260604-yukon-eagle-v3-0-9e3b57d306a8@gmail.com

Changes in v3:
- Changed incorrect "chassis" to "chassis-type" in the device tree.
- Mentioned added vibrator in the commit message.
- Link to v2: https://patch.msgid.link/20260603-yukon-eagle-v2-0-f86b440583f5@gmail.com

Changes in v2:
- Dropped `regulator-always-on` for l3, l6 and l8.
- Mentioned added GPIO buttons and reset input in the commit message.
- Link to v1: https://patch.msgid.link/20260527-yukon-eagle-v1-0-98119d64a71b@gmail.com
