[PATCH 0/8] Add support for Samsung Galaxy tab A (2015) tablets

[Nikita Travkin]

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.

[PATCH 2/8] arm64: dts: qcom: Add device tree for Samsung Galaxy Tab A (2015)

[Nikita Travkin]

From: Jasper Korten <jja2000@gmail.com>

This dts adds support for wifi and lte variants of
Samsung Galaxy Tab A tablets released in 2015. (with both 8.0 and
9.7 inch displays)

Add a device tree for gt58 and gt510 with initial support for:

- SDHCI (internal and external storage)
- USB Device Mode
- UART
- Regulators
- WCNSS (WiFi/BT)
- GPIO keys

Most of the device tree is separated into
msm8916-samsung-gt5-common.dtsi as these devices share a lot of
hardware with each other.

You just added this file in previous patch, so this should be squashed.
Patches should be organized logically and logical change is "new board XYZ".

[PATCH 4/8] arm64: dts: qcom: msm8916-samsung-gt510: Add Vibrator

[Nikita Travkin]

gt510 uses a PWM controllable vibrator, that uses a general purpose
clock output for it's control. Set up the pwm, supply and the vibrator.

Squash. One patch per adding GT510, one for GT58.

> Squash. One patch per adding GT510, one for GT58.
> 

When submitting the series, I decided to not squash the commits to
preserve the authors for the changes as they were made.

I will send a v2, containing two commits for gt58 and gt510 with
the dtsi changes as part of the first one.
