Subject: [PATCH 3/3] arm64: dts: qcom: msm8976-longcheer-l9360: Add initial
 device tree

From: André Apitzsch <git@...tzsch.eu>

This dts adds support for BQ Aquaris X5 Plus (Longcheer L9360) released
in 2016.

Add a device tree with initial support for:

- GPIO keys
- NFC
- SDHCI
- Status LED
- Touchscreen
