404 bool "Freescale MPC8XXX GPIO driver"
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,
411 gpio-controller@fc00 {
413 compatible = "fsl,pq3-gpio";
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
