ARM: dts: qcom: lenovo-lxf-p5100: Add initial device tree
Browse files Browse the repository at this point in the history 
Lenovo Yoga Tab 3 10 LTE is a tablet using the MSM8909 SoC released in 2016.

Add a device tree for with initial support for:

- GPIO keys
- pm8909-vibrator
- SDHCI (internal and external storage)
- UART
- WCNSS (WiFi/BT)
- Regulators
- Touchscreen
- PWM panel backlight
- Hall
- Power LED
- Framebuffer
- USB (Dont Work)
- Magnetometer
