You may want 12 to enable some more options depending on what you want to do. 13 14config PINCTRL_FULL 15 bool "Support full pin controllers" 16 depends on PINCTRL && OF_CONTROL 17 default y 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. 29 30config 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 44config 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. 51 52config PINCONF 53 bool "Support pin configuration controllers" 54 depends on PINCTRL_GENERIC 55 help 56 This option enables pin configuration through the generic pinctrl 57 framework. 58 59config SPL_PINCTRL 60 bool "Support pin controlloers in SPL" 61 depends on SPL && SPL_DM 62 help 63 This option is an SPL-variant of the PINCTRL option. 64 See the help of PINCTRL for details. 65 66config SPL_PINCTRL_FULL 67 bool "Support full pin controllers in SPL" 68 depends on SPL_PINCTRL && SPL_OF_CONTROL 69 default y 70 help 71 This option is an SPL-variant of the PINCTRL_FULL option. 72 See the help of PINCTRL_FULL for details. 73 74config SPL_PINCTRL_GENERIC 75 bool "Support generic pin controllers in SPL" 76 depends on SPL_PINCTRL_FULL 77 default y 78 help 79 This option is an SPL-variant of the PINCTRL_GENERIC option. 80 See the help of PINCTRL_GENERIC for details. 81 82config SPL_PINMUX 83 bool "Support pin multiplexing controllers in SPL" 84 depends on SPL_PINCTRL_GENERIC 85 default y 86 help 87 This option is an SPL-variant of the PINMUX option. 88 See the help of PINMUX for details. 89 90config SPL_PINCONF 91 bool "Support pin configuration controllers in SPL" 92 depends on SPL_PINCTRL_GENERIC 93 help 94 This option is an SPL-variant of the PINCONF option. 95 See the help of PINCONF for details. 96 97if PINCTRL || SPL_PINCTRL 98 99config PINCTRL_SANDBOX 100 bool "Sandbox pinctrl driver" 101 depends on SANDBOX 102 help 103 This enables pinctrl driver for sandbox. Currently, this driver 104 actually does nothing but print debug messages when pinctrl 105 operations are invoked. 106 107endif 108 109endmenu 110
