Subject: [RFC PATCH v2 4/4] arm64: dts: qcom: Add device tree for Longcheer L8150
Longcheer L8150 is a smartphone based on MSM8916 which is
used in several rebrands like the Snapdragon 410
Android One devices or the Wileyfox Swift.
Add a device tree for L8150 with initial support for:
- SDHCI (internal and external storage)
- USB Device Mode
- UART
- Regulators
