Mario Six | d006f68 | 2018-01-15 11:07:48 +0100 | [diff] [blame] | 398 | This driver supports the built-in GPIO controller of MPC8XXX CPUs. |
mario.six@gdsys.cc | 5b59a35 | 2016-05-25 15:15:20 +0200 | [diff] [blame] | 399 | Each GPIO bank is identified by its own entry in the device tree, |
| 400 | i.e. |
| 401 | |
| 402 | gpio-controller@fc00 { |

| 405 | reg = <0xfc00 0x100> |
| 406 | } |

| 409 | setting is honored, so the number of GPIOs for each bank is |

| 411 | 32/32/23 banks of the P1022 SoC). |

| 415 | GPIOs to work as open-drain outputs, is supported. |
