- in DT case, don't do anything in the driver about the GPIO chip select, because it will be handled automatically by the core.
But, i see that gpio_request_one is needed in _setup function in the driver. Except that no other gpio related operation is needed in the driver.
Ideally this code could be moved into the core too - indeed, ideally the non-DT case could be handled by the core too except for the bit where we look up what GPIO to use. -------------- next part -------------- A non-text attachment was scrubbed...
