yes, i believe so, eventually both devm_gpiod_get_array and 
devm_fwnode_gpiod_get_index use of_fwnode_handle(iodev->dev->of_node) in 
this case.

But, i think it's a good idea to introduce a helper to get gpio 
descriptor array with fwnode, i have made a patch, would appreciate it 
if you can help me have a look.

Best regards,

Song
