Subject: [PATCH v2 2/3] arm64: dts: qcom: Add device tree for Samsung Galaxy Tab A 9.7 (2015)

From: Jasper Korten <[email protected]>

The Galaxy Tab A 9.7 (2015) is a Snapdragon 410 based tablet.

This commit introduces basic support for the tablet including the
following features:
- SDHCI (internal and external storage)
- USB Device Mode
- UART
- Regulators
- WCNSS (WiFi/BT)
- GPIO keys
- Fuel gauge
- Touchscreen
- Accelerometer

Part of the DT is split out into a common dtsi since the tablet shares
majority of the design with another variant having a different screen
size.

The node at 0x10 should come before the node at 0x1d.
