tests: spi: add nucleo_g431rb to spi_loopback test in async mode (3c87b7ac) · Commits · Wenxi XU / zephyr

Add nucleo_g431rb to spi_loopback test using spi async configuration. Such that tests do not only run with syncronous spi configuration (nucleo_g474re), but also with the asyncronous configuration. Signed-off-by:
