Subject: [PATCH v3 0/3] Add support for Samsung Galaxy tab A (2015) tablets

This series introduces basic support for two Galaxy Tab A
tablets: 8 and 10 inch variants. They share most of the
hardware and are mainly dffernet by the display.

With this series both tablets gain support for things like
- SDHCI (internal and external storage)
- USB Device Mode
- UART
- Regulators
- WCNSS (WiFi/BT)
- GPIO keys
- Fuel gauge
- Touchscreen
- Accelerometer

In fact, with some additional patches like display and
modem support, that are not included as part of this
series, these tablets can actually reach one's expectations
of what a "normal" tablet should be able to do.

Changes in v2:
- Squashed the commits.

Changes in v3:
- Address Konrad's review comments.

From: Siddharth Manthan <[email protected]>

Galaxy Tab A 8.0 is a tablet, very similar to Tab A 9.7 with major
differences being the display and touchscreen.

Add it's devicetree reusing a common dtsi from gt510.

Subject: [PATCH v3 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.
