Perhaps. I have no hardware to test and the question probably better to be addressed to author(s) of the driver. My scope is to convert to new extension to device property API, so, anyone who will look for examples will not use the old approach. > It's more to the point when counting gpios I think. > > However this driver is not includeing <linux/gpio/consumer.h> > and is this "gpios" property really a consumer property?
