I wonder if this should be set conditionally instead. Maybe set it
to "true" if the "num-cs" property exists?
I'm not too sure, but it seems some other drivers like "spi-sun6i.c",
"spi-stm32.c", "spi-s3c64xx.c", "spi-pic32.c", etc. set it
unconditionally.
Ok, maybe Mark can enlighten us here.
use_gpio_descriptions is just selecting which version of the GPIO APIs
we should use if we're handling GPIOs rather than if we should handle
them.  We've got one last driver using the numerical GPIO APIs, once
that one is converted we should just be able to drop the flag since
everything will be using descriptors.


Thanks for your answer!
