  10         help
  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.

  42           Say yes here to select AT91 PIO GPIO driver. AT91 PIO
  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.

  56           The PIO4 is new version of Atmel PIO controller, which manages
  57           up to 128 fully programmable input/output lines. Each I/O line

  62         bool "Intel Broadwell GPIO driver"
  63         depends on DM
  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.

  96           This controller have single bank (default name "soc"), every
  97           gpio has it's own set of registers.
  98           Only simple GPIO operations are supported (get/set, change of
  99           direction and checking pin function).

 114         help
 115           Deprecated: This should be converted to driver model.
 116
 117           This command provides access to a pca953x GPIO device using the
 118           legacy GPIO interface. Several subcommands are provided which mirror
 119           the standard 'gpio' command. It should use that instead.

 127           Default name for GPIO bank is "pm8916".
 128           Power and reset buttons are placed in "pm8916_key" bank and

 146         depends on DM_GPIO
 147         help
 148           Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
 149           a number of banks (different for each SoC type) each with 32 GPIOs.

 154         bool "Enable sandbox GPIO driver"
 155         depends on SANDBOX && DM && DM_GPIO
 156         help
 157           This driver supports some simulated GPIOs which can be adjusted
 158           using 'back door' functions like sandbox_gpio_set_value(). Then the
 159           GPIOs can be inspected through the normal get_get_value()
 160           interface. The purpose of this is to allow GPIOs to be used as
 161           normal in sandbox, perhaps with test code actually driving the
 162           behaviour of those GPIOs.
 163
 164 config SANDBOX_GPIO_COUNT

 167         default 128
 168         help
 169           The sandbox driver can support any number of GPIOs. Generally these
 170           are specified using the device tree. But you can also have a number
 171           of 'anonymous' GPIOs that do not belong to any device or bank.
 172           Select a suitable value depending on your needs.

 178
 179           This provides a way to looking at the pin state of this device.
 180           This mirrors the 'gpio' command and that should be used in preference
 181           to custom code.

 194           Support for the GPIO controller contained in NVIDIA Tegra186. This
 195           covers both the "main" and "AON" controller instances, even though
 196           they have slightly different register layout.

 251         depends on DM_GPIO
 252         help
 253           Say yes here to provide access to several register-oriented
 254           SMBus I/O expanders, made mostly by NXP or TI.  Compatible
 255           models include:

 260                         pca9556, pca9557, pca9574, tca6408, xra1202
 261
 262           16 bits:      max7312, max7313, pca9535, pca9539, pca9555, pca9575,
 263                         tca6416

 272 config MPC85XX_GPIO
 273         bool "Freescale MPC85XX GPIO driver"
 274         depends on DM_GPIO
 275         help
 276           This driver supports the built-in GPIO controller of MPC85XX CPUs.
 277           Each GPIO bank is identified by its own entry in the device tree,
 278           i.e.
 279
 280           gpio-controller@fc00 {
 281                 #gpio-cells = <2>;
 282                 compatible = "fsl,pq3-gpio";
 283                 reg = <0xfc00 0x100>
 284           }
 285
 286           By default, each bank is assumed to have 32 GPIOs, but the ngpios
 287           setting is honored, so the number of GPIOs for each bank is
 288           configurable to match the actual GPIO count of the SoC (e.g. the
 289           32/32/23 banks of the P1022 SoC).
 290
 291           Aside from the standard functions of input/output mode, and output
 292           value setting, the open-drain feature, which can configure individual
 293           GPIOs to work as open-drain outputs, is supported.
 294
 295           The driver has been tested on MPC85XX, but it is likely that other
 296           PowerQUICC III devices will work as well.
