Re: B210 GPIO SPI support using UHD Python API

You're right that the manual page for the GPIO API does not spell out B210 specifically, but everything there also applies to B210: https://uhd.readthedocs.io/en/latest/page_gpio_api.html [https://uhd.readthedocs.io/en/latest/page_gpio_api.html]
Start slowly, without SPI, and read back known pin values.
