446 help
Mario Six3c216832018-01-15 11:07:48 +0100447 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
mario.six@gdsys.cc07d31f82016-05-25 15:15:20 +0200448 Each GPIO bank is identified by its own entry in the device tree,
449 i.e.
450
451 gpio-controller@fc00 {
452 #gpio-cells = <2>;
453 compatible = "fsl,pq3-gpio";
454 reg = <0xfc00 0x100>
455 }
456
457 By default, each bank is assumed to have 32 GPIOs, but the ngpios
458 setting is honored, so the number of GPIOs for each bank is
459 configurable to match the actual GPIO count of the SoC (e.g. the
460 32/32/23 banks of the P1022 SoC).
461
mario.six@gdsys.cc51781782016-05-25 15:15:22 +0200462 Aside from the standard functions of input/output mode, and output
463 value setting, the open-drain feature, which can configure individual
464 GPIOs to work as open-drain outputs, is supported.

485 Support GPIO access on Nexell SoCs. The GPIOs are arranged into
486 a number of banks (different for each SoC type) each with 32 GPIOs.
487 The GPIOs for a device are defined in the device tree with one node
488 for each bank.
