It's a .dtso overlay source file that compiles into a .dtbo overlay binary file. If you're going to write an overlay source file, then it would make sense to first mention and review the base DT source file (that would be overlayed). WebGPIO conventions¶. Note that this is called a “convention” because you don’t need to do it this way, and it’s no crime if you don’t. There are cases where portability is not the main issue; GPIOs are often used for the kind of board-specific glue logic that may even change between board revisions, and can’t ever be used on a board that’s wired differently. psinergy natural health \\u0026 holistic wellness

Ditto for SPI, MDIO, USB, etc. The only devices which do not require a specific type of parent device are platform_devices (and amba_devices, but more on that later), which will happily live at the base of the Linux /sys/devices tree.
