  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.

  43           controller manages up to 32 fully programmable input/output
  44           lines. Each I/O line may be dedicated as a general-purpose
  45           I/O or be assigned to a function of an embedded peripheral.
  46           The assignment to a function of an embedded peripheral is
  47           the responsibility of AT91 Pinctrl driver. This driver is
  48           responsible for the general-purpose I/O.

  64         help
  65           This driver supports Broadwell U devices which have an expanded
  66           GPIO feature set. The difference is large enough to merit a separate
  67           driver from the common Intel ICH6 driver. It supports a total of
  68           95 GPIOs which can be configured from the device tree.

 128
 129           This command provides access to a pca953x GPIO device using the
 130           legacy GPIO interface. Several subcommands are provided which mirror
 131           the standard 'gpio' command. It should use that instead.

 161           a number of banks (different for each SoC type) each with 32 GPIOs.

 166         bool "Enable sandbox GPIO driver"
 167         depends on SANDBOX && DM && DM_GPIO
 168         help
 169           This driver supports some simulated GPIOs which can be adjusted
 170           using 'back door' functions like sandbox_gpio_set_value(). Then the
 171           GPIOs can be inspected through the normal get_get_value()
 172           interface. The purpose of this is to allow GPIOs to be used as
 173           normal in sandbox, perhaps with test code actually driving the
 174           behaviour of those GPIOs.
 175

 181           The sandbox driver can support any number of GPIOs. Generally these
 182           are specified using the device tree. But you can also have a number
 183           of 'anonymous' GPIOs that do not belong to any device or bank.
 184           Select a suitable value depending on your needs.

 189           DEPRECATED - This needs conversion to driver model
 190
 191           This provides a way to looking at the pin state of this device.
 192           This mirrors the 'gpio' command and that should be used in preference
 193           to custom code.

 264         help
 265           Say yes here to provide access to several register-oriented
 266           SMBus I/O expanders, made mostly by NXP or TI.  Compatible

 284 config MPC8XXX_GPIO
 285         bool "Freescale MPC8XXX GPIO driver"
 286         depends on DM_GPIO
 287         help
 288           This driver supports the built-in GPIO controller of MPC8XXX CPUs.
 289           Each GPIO bank is identified by its own entry in the device tree,
 290           i.e.
 291
 292           gpio-controller@fc00 {
 293                 #gpio-cells = <2>;
 294                 compatible = "fsl,pq3-gpio";
 295                 reg = <0xfc00 0x100>
 296           }
 297
 298           By default, each bank is assumed to have 32 GPIOs, but the ngpios
 299           setting is honored, so the number of GPIOs for each bank is
 300           configurable to match the actual GPIO count of the SoC (e.g. the
 301           32/32/23 banks of the P1022 SoC).
 302
 303           Aside from the standard functions of input/output mode, and output
 304           value setting, the open-drain feature, which can configure individual
 305           GPIOs to work as open-drain outputs, is supported.
