I am trying to use devm_gpiod_get now
but before I have to add the gpios via the mapping as decscribed in

Hi,

I am actually stucking to get the ACPI handle via
handle = ACPI_HANDLE(&arizona->dev)
it complaints about dev->fwnode

I am looking to get it working with acpi_fwnode_handle() at the moment
