7config PINCTRL
8 bool "Support pin controllers"
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.
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.

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
Marek BehĂșn44f62e92018-03-02 09:56:00 +010050 framework. Most SoCs have their own multiplexing arrangement where
51 a single pin can be used for several functions. An SoC pinctrl driver
52 allows the required function to be selected for each pin.
Simon Glass8d6510d2015-08-30 16:55:12 -060053 The driver is typically controlled by the device tree.

92 See the help of PINMUX for details.
Simon Glass8d6510d2015-08-30 16:55:12 -060093 The pinctrl subsystem can add a substantial overhead to the SPL
94 image since it typically requires quite a few tables either in the
95 driver or in the device tree. If this is acceptable and you need
96 to adjust pin multiplexing in SPL in order to boot into U-Boot,
97 enable this option. You will need to enable device tree in SPL
98 for this to work.

122 This option is to enable the AT91 pinctrl driver for AT91 PIO
123 controller.
124
125 AT91 PIO controller is a combined gpio-controller, pin-mux and
126 pin-config module. Each I/O pin may be dedicated as a general-purpose
127 I/O or be assigned to a function of an embedded peripheral. Each I/O
128 pin has a glitch filter providing rejection of glitches lower than
129 one-half of peripheral clock cycle and a debouncing filter providing
130 rejection of unwanted pulses from key or push button operations. You
131 can also control the multi-driver capability, pull-up and pull-down
132 feature on each I/O pin.
