Subject: [PATCH v2 2/2] ARM: dts: qcom-msm8226-samsung-ms013g: Add initial device tree
Samsung Galaxy Grand 2 is a phone based on MSM8226. It's similar to the
other Samsung devices based on MSM8226 with only a few minor differences.
The device trees contain initial support with:
- GPIO keys
- Regulator haptic
- SDHCI (internal and external storage)
- UART (on USB connector via the TI TSU6721 MUIC)
- Regulators
- Touchscreen
- Accelerometer
