Please find attached a first try. I tested all GPIOs with a MCP2515 connected to a Raspberry Pi 3 Model B.
I have two questions:
1. How to handle power management? Does the driver have to restore the previous gpio state?
2. I used spi_device.modalias as name for the gpiochip because that translates nicely to mcp{251{0,5},25625} at least when loaded by the device tree. I didn't test but suppose that the same name will be used when loaded without device tree. Is that correct?
