Spi device tree source code

2022-08-11 Thursday

Notes on SPI device tree source, with goal to add SPI device to modified RPi Pico DTS files, which build firmware to run on Sparkfun DEV-18288 board.

In Zephyr RTOS' supported board dts files find . . .

^ YAML device bindings files

To support a typical development kit or custom board with multiple peripherals we need a device bindings file comparable to this ... bindings file:
