406 help
407 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
408 Each GPIO bank is identified by its own entry in the device tree,

413 compatible = "fsl,pq3-gpio";
414 reg = <0xfc00 0x100>
415 }
416
417 By default, each bank is assumed to have 32 GPIOs, but the ngpios
418 setting is honored, so the number of GPIOs for each bank is
419 configurable to match the actual GPIO count of the SoC (e.g. the
420 32/32/23 banks of the P1022 SoC).

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