9 Enable support for GPIOs (General-purpose Input/Output) in U-Boot.
10 GPIOs allow U-Boot to read the state of an input line (high or
11 low) and set the state of an output line. This can be used to
12 drive LEDs, control power to various system parts and read user
13 input. GPIOs can be useful to enable a 'sign-of-life' LED,
14 for example. Enable this option to build the drivers in
15 drivers/gpio as part of an U-Boot build.

426 Add support for the Marvell Octeon GPIO driver. This is used with
427 various Octeon parts such as Octeon II/III and OcteonTX/TX2.
428 Octeon II/III has 32 GPIOs (count defined via DT) and OcteonTX/TX2
429 has 64 GPIOs (count defined via internal register).

518 help
Mario Six3c216832018-01-15 11:07:48 +0100519 This driver supports the built-in GPIO controller of MPC8XXX CPUs.
mario.six@gdsys.cc07d31f82016-05-25 15:15:20 +0200520 Each GPIO bank is identified by its own entry in the device tree,
521 i.e.

524 #gpio-cells = <2>;
525 compatible = "fsl,pq3-gpio";
526 reg = <0xfc00 0x100>
527 }
528
529 By default, each bank is assumed to have 32 GPIOs, but the ngpios
530 setting is honored, so the number of GPIOs for each bank is
531 configurable to match the actual GPIO count of the SoC (e.g. the
532 32/32/23 banks of the P1022 SoC).

mario.six@gdsys.cc51781782016-05-25 15:15:22 +0200534 Aside from the standard functions of input/output mode, and output
535 value setting, the open-drain feature, which can configure individual
536 GPIOs to work as open-drain outputs, is supported.
