   9         depends on DM
  10         help
  11           This enables the basic support for pinctrl framework.  You may want
  12           to enable some more options depending on what you want to do.

  14 config PINCTRL_FULL
  15         bool "Support full pin controllers"

  18         help
  19           This provides Linux-compatible device tree interface for the pinctrl
  20           subsystem.  This feature depends on device tree configuration because
  21           it parses a device tree to look for the pinctrl device which the
  22           peripheral device is associated with.
  23
  24           If this option is disabled (it is the only possible choice for non-DT
  25           boards), the pinctrl core provides no systematic mechanism for
  26           identifying peripheral devices, applying needed pinctrl settings.
  27           It is totally up to the implementation of each low-level driver.
  28           You can save memory footprint in return for some limitations.

  30 config PINCTRL_GENERIC
  31         bool "Support generic pin controllers"
  32         depends on PINCTRL_FULL
  33         default y
  34         help
  35           Say Y here if you want to use the pinctrl subsystem through the
  36           generic DT interface.  If enabled, some functions become available
  37           to parse common properties such as "pins", "groups", "functions" and
  38           some pin configuration parameters.  It would be easier if you only
  39           need the generic DT interface for pin muxing and pin configuration.
  40           If you need to handle vendor-specific DT properties, you can disable
  41           this option and implement your own set_state callback in the pinctrl
  42           operations.
  43
  44 config PINMUX
  45         bool "Support pin multiplexing controllers"
  46         depends on PINCTRL_GENERIC
  47         default y
  48         help
  49           This option enables pin multiplexing through the generic pinctrl
  50           framework. Most SoCs have their own own multiplexing arrangement
  51           where a single pin can be used for several functions. An SoC pinctrl
  52           driver allows the required function to be selected for each pin.
  53           The driver is typically controlled by the device tree.

  55 config PINCONF
  56         bool "Support pin configuration controllers"

  87         depends on SPL_PINCTRL_GENERIC
  88         default y
  89         help
  90           This option is an SPL-variant of the PINMUX option.
  91           See the help of PINMUX for details.
  92           The pinctrl subsystem can add a substantial overhead to the SPL
  93           image since it typically requires quite a few tables either in the
  94           driver or in the device tree. If this is acceptable and you need
  95           to adjust pin multiplexing in SPL in order to boot into U-Boot,
  96           enable this option. You will need to enable device tree in SPL
  97           for this to work.
