GPIO consumers shall use devm_gpiod_get() or devm_gpiod_get_index()
to get an abstract GPIO descriptor. This already works with DT and ACPI
alike, driver authors just haven't caught up. Yes we have to patch ourselves
through this entire GPIO number exodus ...
Documentation/gpio/consumer.txt
GPIOs, clocks, regulators and pins are already on abstract handles
tied into the device model, so what am I missing?
