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.
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. 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.
53	  The driver is typically controlled by the device tree.
54
55config PINCONF
56	bool "Support pin configuration controllers"
57	depends on PINCTRL_GENERIC
58	help
59	  This option enables pin configuration through the generic pinctrl
60	  framework.
61
62config PINCONF_RECURSIVE
63	bool "Support recursive binding for pin configuration nodes"
64	depends on PINCTRL_FULL
65	default n if ARCH_STM32MP
66	default y
67	help
68	  In the Linux pinctrl binding, the pin configuration nodes need not be
69	  direct children of the pin controller device (may be grandchildren for
70	  example). It is define is each individual pin controller device.
71	  Say Y here if you want to keep this behavior with the pinconfig
72	  u-class: all sub are recursively bounded.
73	  If the option is disabled, this behavior is deactivated and only
74	  the direct children of pin controller will be assumed as pin
75	  configuration; you can save memory footprint when this feature is
76	  no needed.
77
78config SPL_PINCTRL
79	bool "Support pin controllers in SPL"
80	depends on SPL && SPL_DM
81	help
82	  This option is an SPL-variant of the PINCTRL option.
83	  See the help of PINCTRL for details.
84
85config TPL_PINCTRL
86	bool "Support pin controllers in TPL"
87	depends on TPL && TPL_DM
88	help
89	  This option is an TPL variant of the PINCTRL option.
90	  See the help of PINCTRL for details.
91
92config VPL_PINCTRL
93	bool "Support pin controllers in VPL"

139	bool "Support pin multiplexing controllers in SPL"
140	depends on SPL_PINCTRL_GENERIC
141	default y
142	help
143	  This option is an SPL-variant of the PINMUX option.
144	  See the help of PINMUX for details.
145	  The pinctrl subsystem can add a substantial overhead to the SPL
146	  image since it typically requires quite a few tables either in the
147	  driver or in the device tree. If this is acceptable and you need
148	  to adjust pin multiplexing in SPL in order to boot into U-Boot,
149	  enable this option. You will need to enable device tree in SPL
150	  for this to work.

201	help
202	  This option is to enable the AT91 pinctrl driver for AT91 PIO
203	  controller.
204
205	  AT91 PIO controller is a combined gpio-controller, pin-mux and
206	  pin-config module. Each I/O pin may be dedicated as a general-purpose
207	  I/O or be assigned to a function of an embedded peripheral. Each I/O
208	  pin has a glitch filter providing rejection of glitches lower than
209	  one-half of peripheral clock cycle and a debouncing filter providing
210	  rejection of unwanted pulses from key or push button operations. You
211	  can also control the multi-driver capability, pull-up and pull-down
212	  feature on each I/O pin.
