  11           Enable driver model for GPIO access. The standard GPIO
  12           interface (gpio_get_value(), etc.) is then implemented by
  13           the GPIO uclass. Drivers provide methods to query the
  14           particular GPIOs that they provide. The uclass interface
  15           is defined in include/asm-generic/gpio.h.

  72           driver from the common Intel ICH6 driver. It supports a total of
  73           95 GPIOs which can be configured from the device tree.

 108           the number of available GPIOs with a minimum number of
 109           additional pins on the device. The primary purpose of the

 146           legacy GPIO interface. Several subcommands are provided which mirror
 147           the standard 'gpio' command. It should use that instead.

 187           GPIOs can be inspected through the normal get_get_value()
 188           interface. The purpose of this is to allow GPIOs to be used as
 189           normal in sandbox, perhaps with test code actually driving the
 190           behaviour of those GPIOs.

 197           The sandbox driver can support any number of GPIOs. Generally these
 198           are specified using the device tree. But you can also have a number

 332         help
 333           This driver supports the built-in GPIO controller of MPC8XXX CPUs.
 334           Each GPIO bank is identified by its own entry in the device tree,
 335           i.e.
 336

 341           }
 342
 343           By default, each bank is assumed to have 32 GPIOs, but the ngpios
 344           setting is honored, so the number of GPIOs for each bank is
 345           configurable to match the actual GPIO count of the SoC (e.g. the
 346           32/32/23 banks of the P1022 SoC).
 347
 348           Aside from the standard functions of input/output mode, and output
 349           value setting, the open-drain feature, which can configure individual
 350           GPIOs to work as open-drain outputs, is supported.
