arm64: dts: qcom: Add device tree for Samsung Galaxy Tab A 9.7 (2015)
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.
