   7 config DM_GPIO

   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.

  19         depends on DM_GPIO
  20         help
  21           Select this to enable PIO for Altera devices. Please find
  22           details on the "Embedded Peripherals IP User Guide" of Altera.

  33         depends on DM
  34         default n
  35         help
  36           Say yes here to support the Atmel PIO4 driver.
  37           The PIO4 is new version of Atmel PIO controller, which manages
  38           up to 128 fully programmable input/output lines. Each I/O line
  39           may be dedicated as a general purpose I/O or be assigned to
  40           a function of an embedded peripheral.

  42 config INTEL_BROADWELL_GPIO
  43         bool "Intel Broadwell GPIO driver"
  44         depends on DM
  45         help
  46           This driver supports Broadwell U devices which have an expanded
  47           GPIO feature set. The difference is large enough to merit a separate
  48           driver from the common Intel ICH6 driver. It supports a total of
  49           95 GPIOs which can be configured from the device tree.

  55         help
  56           Support for the LPC32XX GPIO driver.

  59         bool "Qualcomm GPIO driver"
  60         depends on DM_GPIO
  61         default n
  62         help
  63           Support GPIO controllers on Qualcomm Snapdragon family of SoCs.
  64           This controller have single bank (default name "soc"), every
  65           gpio has it's own set of registers.
  66           Only simple GPIO operations are supported (get/set, change of
  67           direction and checking pin function).
  68           Supported devices:
  69           - APQ8016
  70           - MSM8916

  74         depends on DM_GPIO && PMIC_PM8916
  75         help
  76           Support for GPIO pins and power/reset buttons found on
  77           Qualcomm PM8916 PMIC.
  78           Default name for GPIO bank is "pm8916".
  79           Power and reset buttons are placed in "pm8916_key" bank and
  80           have gpio numbers 0 and 1 respectively.
  81
  82 config ROCKCHIP_GPIO
  83         bool "Rockchip GPIO driver"
  84         depends on DM_GPIO
  85         help
  86           Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
  87           a number of banks (different for each SoC type) each with 32 GPIOs.
  88           The GPIOs for a device are defined in the device tree with one node
  89           for each bank.

  91 config SANDBOX_GPIO
  92         bool "Enable sandbox GPIO driver"
  93         depends on SANDBOX && DM && DM_GPIO
  94         help
  95           This driver supports some simulated GPIOs which can be adjusted
  96           using 'back door' functions like sandbox_gpio_set_value(). Then the
  97           GPIOs can be inspected through the normal get_get_value()
  98           interface. The purpose of this is to allow GPIOs to be used as
  99           normal in sandbox, perhaps with test code actually driving the
 100           behaviour of those GPIOs.
 101
 102 config SANDBOX_GPIO_COUNT
 103         int "Number of sandbox GPIOs"
 104         depends on SANDBOX_GPIO
 105         default 128
 106         help
 107           The sandbox driver can support any number of GPIOs. Generally these
 108           are specified using the device tree. But you can also have a number
 109           of 'anonymous' GPIOs that do not belong to any device or bank.
 110           Select a suitable value depending on your needs.
