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" | |
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 | ||
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. | |

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 | |
458a0700 SG |
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. | |

90 | This option is an SPL-variant of the PINMUX option. | |
91 | See the help of PINMUX for details. | |
458a0700 SG |
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. | |

124 | AT91 PIO controller is a combined gpio-controller, pin-mux and | |

126 | I/O or be assigned to a function of an embedded peripheral. Each I/O | |
127 | pin has a glitch filter providing rejection of glitches lower than | |
128 | one-half of peripheral clock cycle and a debouncing filter providing | |
129 | rejection of unwanted pulses from key or push button operations. You | |
130 | can also control the multi-driver capability, pull-up and pull-down | |
131 | feature on each I/O pin. | |
