MikroBUS is an open standard  developed by MikroElektronika for connecting
add-on boards to microcontrollers or microprocessors. It essentially
allows you to easily expand the functionality of your main boards using
these add-on boards.

This patchset adds mikroBUS as a Linux bus type and provides a driver to
parse, and flash mikroBUS manifest and register the mikroBUS board.

The v1 and v2 of this patchset was submitted by Vaishnav M A back in
2020. This patchset also includes changes made over the years as part of
BeagleBoards kernel.

Link: https://lore.kernel.org/lkml/20200818124815.11029-1-vaishnav@beagleboard.org/ Patch v2

Changes in v3:
- Use phandle instead of busname for spi
- Use spi board info for registering new device
- Convert dt bindings to yaml
- Add support for clickID
- Code cleanup and style changes
- Additions required to spi, serdev, w1 and regulator subsystems

Changes in v2:
- support for adding mikroBUS ports from DT overlays,
- remove debug sysFS interface for adding mikrobus ports,
- consider extended pin usage/deviations from mikrobus standard
  specifications
- use greybus CPort protocol enum instead of new protocol enums
- Fix cases of wrong indentation, ignoring return values, freeing allocated
  resources in case of errors and other style suggestions in v1 review.
