[PATCH 05/26] Staging: fbtft: fbtft-device: Switch to the gpio descriptor interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This switches the fbtft-device.c to use GPIO descriptors
rather than numerical gpios: Remove gpios from platform
device structure. Neither assign statically numbers to gpios
in platform device nor allow gpios to be parsed as module
parameters.
