| config PINCTRL |
| bool "Support pin controllers" |
| depends on DM |
| help |
| This enables the basic support for pinctrl framework. You may want |
| to enable some more options depending on what you want to do. |
| |
| config PINCTRL_FULL |
| bool "Support full pin controllers" |
| depends on PINCTRL && OF_CONTROL |
| default y |
| help |
| This provides Linux-compatible device tree interface for the pinctrl |
| subsystem. This feature depends on device tree configuration because |
| it parses a device tree to look for the pinctrl device which the |
| peripheral device is associated with. |
| |
| If this option is disabled (it is the only possible choice for non-DT |
| boards), the pinctrl core provides no systematic mechanism for |
| identifying peripheral devices, applying needed pinctrl settings. |
| It is totally up to the implementation of each low-level driver. |
| You can save memory footprint in return for some limitations. |
| |
| config PINCTRL_GENERIC |
| bool "Support generic pin controllers" |
| depends on PINCTRL_FULL |
| default y |
| help |
| Say Y here if you want to use the pinctrl subsystem through the |
| generic DT interface. If enabled, some functions become available |
| to parse common properties such as "pins", "groups", "functions" and |
| some pin configuration parameters. It would be easier if you only |
| need the generic DT interface for pin muxing and pin configuration. |
| If you need to handle vendor-specific DT properties, you can disable |
| this option and implement your own set_state callback in the pinctrl |
| operations. |
| |
| config PINMUX |
| bool "Support pin multiplexing controllers" |
| depends on PINCTRL_GENERIC |
| default y |
| help |
| This option enables pin multiplexing through the generic pinctrl |
| framework. Most SoCs have their own own multiplexing arrangement |
| where a single pin can be used for several functions. An SoC pinctrl |
| driver allows the required function to be selected for each pin. |
| The driver is typically controlled by the device tree. |
| |
| config PINCONF |
| bool "Support pin configuration controllers" |
| depends on PINCTRL_GENERIC |
| help |
| This option enables pin configuration through the generic pinctrl |
| framework. |
| |
| config SPL_PINCTRL |
| bool "Support pin controlloers in SPL" |
| depends on SPL && SPL_DM |
| help |
| This option is an SPL-variant of the PINCTRL option. |
| See the help of PINCTRL for details. |
| |
| config SPL_PINCTRL_FULL |
| bool "Support full pin controllers in SPL" |
| depends on SPL_PINCTRL && SPL_OF_CONTROL |
| default y |
| help |
| This option is an SPL-variant of the PINCTRL_FULL option. |
| See the help of PINCTRL_FULL for details. |
| |
| config SPL_PINCTRL_GENERIC |
| bool "Support generic pin controllers in SPL" |
| depends on SPL_PINCTRL_FULL |
| default y |
| help |
| This option is an SPL-variant of the PINCTRL_GENERIC option. |
| See the help of PINCTRL_GENERIC for details. |
| |
| config SPL_PINMUX |
| bool "Support pin multiplexing controllers in SPL" |
| depends on SPL_PINCTRL_GENERIC |
| default y |
| help |
| This option is an SPL-variant of the PINMUX option. |
| See the help of PINMUX for details. |
| The pinctrl subsystem can add a substantial overhead to the SPL |
| image since it typically requires quite a few tables either in the |
| driver or in the device tree. If this is acceptable and you need |
| to adjust pin multiplexing in SPL in order to boot into U-Boot, |
| enable this option. You will need to enable device tree in SPL |
| for this to work. |
| |
| config SPL_PINCONF |
| bool "Support pin configuration controllers in SPL" |
| depends on SPL_PINCTRL_GENERIC |
| help |
| This option is an SPL-variant of the PINCONF option. |
| See the help of PINCONF for details. |

| This option is to enable the AT91 pinctrl driver for AT91 PIO4 |
| controller which is available on SAMA5D2 SoC. |

| actually does nothing but print debug messages when pinctrl |
| operations are invoked. |

| config PIC32_PINCTRL |

| peripheral available on Microchip PIC32 SoCs. This driver is controlled |
