easytarget-MQ-Pro-IO/precompiled-trees

Precompiled device trees:

Each folder contains a .dtb file, which is the compiled device tree itself, plus a .dts with the original source and a .gpio file showing the GPIO pin mappings.

Generic

The generic device tree I will use in my project, suitable for many occasions

• Has 2x UART (plus the console uart), 2x I2C. 1xSPI
• 12 unassigned GPIO pins

Serial

Four UART interfaces and Four I2C interfaces

• Has 4x UART (plus the console uart), 4x I2C
• UART3 has RTC/CTS pins available too
• 10 unassigned GPIO pins

SPI

SPI plus Serial interfaces

• Has 3x UART (plus the console uart), 3x I2C. 1xSPI
• 8 unassigned GPIO pins

SunXI

Vanilla, unpopulated, upstream

• Has the console uart, nothing more
• 26 unassigned GPIO pins!

DO NOT USE

• Included for completeness, this is the default device tree you get with the Ubuntu image.
• Has the console uart, 1x I2C. 1xSPI
• 15 unassigned GPIO pins, 3 pre-assigned to pinctl
