Hi Will,
You've probably already included this in the spi_config struct, but
just in case I wanted to make sure you can dynamically change the SPI
speed even after the spi bus has been initialized once?
The use case I have in mind is SD cards communicating over the SPI bus
where you need to start the communication at a fairly slow clock
speed, and once everything is setup you can jump to a much faster
clock. I'm sure it's already in there though.
The callbacks below seem sensible to me based on the drivers I've
written in the past.
Being able to bit-bang SPI at a lower level with any GPIO pins would
be a nice plus, but hardly a deal breaker and that is a layer lower
anyway.
Agree with all the other comments, just wanted to +1 this last part.
I think this belongs in a higher layer SPI driver, that can either
bitbang (using hal_gpio*) or use hal_spi. Marko did something similar
with UART, generating 9600 baud, because the Arduino Primo boards use
Nordic’s (1!) UART to talk with the ESP8266.
