  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.

  22           Support for the LPC32XX GPIO driver.

  27         help
  28           This driver supports some simulated GPIOs which can be adjusted
  29           using 'back door' functions like sandbox_gpio_set_value(). Then the
  30           GPIOs can be inspected through the normal get_get_value()
  31           interface. The purpose of this is to allow GPIOs to be used as
  32           normal in sandbox, perhaps with test code actually driving the
  33           behaviour of those GPIOs.

  35 config SANDBOX_GPIO_COUNT
  36         int "Number of sandbox GPIOs"
  37         depends on SANDBOX_GPIO
  38         default 128
  39         help
  40           The sandbox driver can support any number of GPIOs. Generally these
  41           are specified using the device tree. But you can also have a number
  42           of 'anonymous' GPIOs that do not belong to any device or bank.
  43           Select a suitable value depending on your needs.

  45 config VYBRID_GPIO
  46         bool "Vybrid GPIO driver"

  48         default n
  49         help
  50           Say yes here to support Vybrid vf610 GPIOs.
