7 config 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 
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.
43 
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
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.
54 
55 config 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 
62 config SPL_PINCTRL
63 	bool "Support pin controllers in SPL"
64 	depends on SPL && SPL_DM
65 	help
66 	  This option is an SPL-variant of the PINCTRL option.
67 	  See the help of PINCTRL for details.
68 
69 config SPL_PINCTRL_FULL
70 	bool "Support full pin controllers in SPL"
71 	depends on SPL_PINCTRL && SPL_OF_CONTROL
72 	default n if TARGET_STM32F746_DISCO
73 	default y
74 	help
75 	  This option is an SPL-variant of the PINCTRL_FULL option.
76 	  See the help of PINCTRL_FULL for details.
77 
78 config SPL_PINCTRL_GENERIC
79 	bool "Support generic pin controllers in SPL"
80 	depends on SPL_PINCTRL_FULL
81 	default y
82 	help
83 	  This option is an SPL-variant of the PINCTRL_GENERIC option.
84 	  See the help of PINCTRL_GENERIC for details.
85 
86 config SPL_PINMUX
87 	bool "Support pin multiplexing controllers in SPL"
88 	depends on SPL_PINCTRL_GENERIC
89 	default y
90 	help
91 	  This option is an SPL-variant of the PINMUX option.
92 	  See the help of PINMUX for details.
93 	  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.
99 
100 config SPL_PINCONF
101 	bool "Support pin configuration controllers in SPL"
102 	depends on SPL_PINCTRL_GENERIC
103 	help
104 	  This option is an SPL-variant of the PINCONF option.
105 	  See the help of PINCONF for details.

110 	bool "QCA/Athores ar933x pin control driver"
111 	depends on DM && SOC_AR933X
112 	help
113 	  Support pin multiplexing control on QCA/Athores ar933x SoCs.
114 	  The driver is controlled by a device tree node which contains
115 	  both the GPIO definitions and pin control functions for each
116 	  available multiplex function.
117 
118 config PINCTRL_AT91
119 	bool "AT91 pinctrl driver"
120 	depends on DM
121 	help
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.
133 
134 config PINCTRL_AT91PIO4
135 	bool "AT91 PIO4 pinctrl driver"
136 	depends on DM
137 	help

139 	  controller which is available on SAMA5D2 SoC.

147 	  remappable peripheral available on Microchip PIC32
148 	  SoCs. This driver is controlled by a device tree node which
149 	  contains both GPIO defintion and pin control functions.
