Subject: [PATCH v2 3/3] arm64: dts: qcom: msm8939-wingtech-wt82918: Add
 Lenovo Vibe K5 devices

From: Adam Słaboń <asaillen@...tonmail.com>

This commit introduces multiple hardware variants of Lenovo Vibe K5.

- A6020a40 (msm8929-wingtech-wt82918hd)
- A6020a46/A6020l36 (msm8939-wingtech-wt82918)
- A6020a40 S616 H39 (msm8939-wingtech-wt82918hd)

These devices are added with support for many features, notably:

- Basic features like USB, mmc/sd storage, wifi, buttons, leds;
- Accelerometer;
- Touchscreen;
- Sound and modem.

Note that "HD" variant of K5 is based on msm8929 which is a lower bin
of msm8939 SoC. A simple dtsi is added for this soc along with the new
devices.

Unfortunately, despite the heavy similarities, the combination of minor
differences between variants make them incompatible between each other.
