2018-03-10drivers/bus: Pull out software SPI implementation to dedicated driver.Damien George
This patch takes the software SPI implementation from extmod/machine_spi.c and moves it to a dedicated file in drivers/bus/softspi.c. This allows the SPI driver to be used independently of the uPy runtime, making it a more general component.
