1* Atmel AT91 Pinmux Controller
2
3The AT91 Pinmux Controler, enables the IC
4to share one PAD to several functional blocks. The sharing is done by
5multiplexing the PAD input/output signals. For each PAD there are up to
68 muxing options (called periph modes). Since different modules require
7different PAD settings (like pull up, keeper, etc) the contoller controls
8also the PAD settings parameters.
9
10Please refer to pinctrl-bindings.txt in this directory for details of the
11common pinctrl bindings used by client devices, including the meaning of the
12phrase "pin configuration node".
13
14Atmel AT91 pin configuration node is a node of a group of pins which can be
15used for a specific device or function. This node represents both mux and config
16of the pins in that group. The 'pins' selects the function mode(also named pin
17mode) this pin can work on and the 'config' configures various pad settings
18such as pull-up, multi drive, etc.
19
20Required properties for iomux controller:
21- compatible: "atmel,at91rm9200-pinctrl"
22- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
23 configured in this periph mode. All the periph and bank need to be describe.
24
25How to create such array:
26
27Each column will represent the possible peripheral of the pinctrl
28Each line will represent a pio bank
29
30Take an example on the 9260
31Peripheral: 2 ( A and B)
32Bank: 3 (A, B and C)
33=>
34
35 /* A B */
36 0xffffffff 0xffc00c3b /* pioA */
37 0xffffffff 0x7fff3ccf /* pioB */
38 0xffffffff 0x007fffff /* pioC */
39
40For each peripheral/bank we will descibe in a u32 if a pin can can be
41configured in it by putting 1 to the pin bit (1 << pin)
42
43Let's take the pioA on peripheral B

81Required properties for pin configuration node:
82- atmel,pins: 4 integers array, represents a group of pins mux and config
83 setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
84 The PERIPH 0 means gpio.
85
86Bits used for CONFIG:
87PULL_UP(1 << 0): indicate this pin need a pull up.
88MULTIDRIVE(1 << 1): indicate this pin need to be configured as multidrive.
89
90NOTE:
91Some requirements for using atmel,at91rm9200-pinctrl binding:
921. We have pin function node defined under at91 controller node to represent
93 what pinmux functions this SoC supports.
942. The driver can use the function node's name and pin configuration node's
95 name describe the pin function and group hierarchy.
96 For example, Linux at91 pinctrl driver takes the function node's name
97 as the function name and pin configuration node's name as group name to
98 create the map table.
993. Each pin configuration node should have a phandle, devices can set pins
100 configurations by referring to the phandle of that pin configuration node.
1014. The gpio controller must be describe in the pinctrl simple-bus.

107 #size-cells = <1>;
