GpioPadDescriptor

Bits	Description
7-5	Controller index
4-3	Port index
2-0	Pin number

OpenSessionForDev

Takes a raw #GpioPadDescriptor and returns an #IPadSession session for it.

OpenSession

Same thing as #OpenSessionForDev except it takes a GpioPadName which is then converted to a #GpioPadDescriptor. Returns an #IPadSession session.

OpenSessionForTest

Same as #OpenSession but panics on failure.

OpenSession2

Same as #OpenSession but takes a DeviceCode instead of a GpioPadName and an u32 DeviceUnk.

IPadSession

This is "nn::gpio::IPadSession".
