   9         depends on DM
  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.

  57           up to 128 fully programmable input/output lines. Each I/O line

  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.

  91           gpio has it's own set of registers.
  92           Only simple GPIO operations are supported (get/set, change of
  93           direction and checking pin function).
  94           Supported devices:

 111           Qualcomm PM8916 PMIC.
 112           Default name for GPIO bank is "pm8916".
 113           Power and reset buttons are placed in "pm8916_key" bank and
 114           have gpio numbers 0 and 1 respectively.

 125         depends on DM_GPIO
 126         help
 127           Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
 128           a number of banks (different for each SoC type) each with 32 GPIOs.
 129           The GPIOs for a device are defined in the device tree with one node
 130           for each bank.

 133         bool "Enable sandbox GPIO driver"
 134         depends on SANDBOX && DM && DM_GPIO
 135         help
 136           This driver supports some simulated GPIOs which can be adjusted
 137           using 'back door' functions like sandbox_gpio_set_value(). Then the
 138           GPIOs can be inspected through the normal get_get_value()
 139           interface. The purpose of this is to allow GPIOs to be used as
 140           normal in sandbox, perhaps with test code actually driving the
 141           behaviour of those GPIOs.
 142

 147         help
 148           The sandbox driver can support any number of GPIOs. Generally these
 149           are specified using the device tree. But you can also have a number
 150           of 'anonymous' GPIOs that do not belong to any device or bank.
 151           Select a suitable value depending on your needs.

 162         depends on DM_GPIO
 163         help
 164           Support for the GPIO controller contained in NVIDIA Tegra186. This
 165           covers both the "main" and "AON" controller instances, even though
 166           they have slightly different register layout.

 193           Device model driver support for STM32 GPIO controller. It should be
 194           usable on many stm32 families like stm32f4 & stm32H7.

 216           shift registers, such as 74lv165, 74hc595.

 222         help
 223           Say yes here to provide access to several register-oriented

 230                         pca9556, pca9557, pca9574, tca6408, xra1202
 231
 232           16 bits:      max7312, max7313, pca9535, pca9539, pca9555, pca9575,
 233                         tca6416

 239           Now, max 24 bits chips and PCA953X compatible chips are
 240           supported
 241
 242 config MPC85XX_GPIO
 243         bool "Freescale MPC85XX GPIO driver"
 244         depends on DM_GPIO
 245         help
 246           This driver supports the built-in GPIO controller of MPC85XX CPUs.
 247           Each GPIO bank is identified by its own entry in the device tree,
 248           i.e.
 249
 250           gpio-controller@fc00 {
 251                 #gpio-cells = <2>;
 252                 compatible = "fsl,pq3-gpio";
 253                 reg = <0xfc00 0x100>
 254           }
 255
 256           By default, each bank is assumed to have 32 GPIOs, but the ngpios
 257           setting is honored, so the number of GPIOs for each bank is
 258           configurable to match the actual GPIO count of the SoC (e.g. the
 259           32/32/23 banks of the P1022 SoC).
 260
 261           Aside from the standard functions of input/output mode, and output
 262           value setting, the open-drain feature, which can configure individual
 263           GPIOs to work as open-drain outputs, is supported.
 264
 265           The driver has been tested on MPC85XX, but it is likely that other
 266           PowerQUICC III devices will work as well.
