interface (gpio_get_value(), etc.) is then implemented by

the GPIO uclass. Drivers provide methods to query the

particular GPIOs that they provide. The uclass interface

By default, each bank is assumed to have 32 GPIOs, but the ngpios

setting is honored, so the number of GPIOs for each bank is

configurable to match the actual GPIO count of the SoC (e.g. the

32/32/23 banks of the P1022 SoC).

Aside from the standard functions of input/output mode, and output

GPIOs to work as open-drain outputs, is supported.
