* Atmel AT91 Pinmux Controller
|
||||
|
||||
The AT91 Pinmux Controler, enables the IC
|
||||
to share one PAD to several functional blocks. The sharing is done by
|
||||
multiplexing the PAD input/output signals. For each PAD there are up to
|
||||
8 muxing options (called periph modes). Since different modules require
|
||||
different PAD settings (like pull up, keeper, etc) the contoller controls
|
||||
also the PAD settings parameters.
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
Atmel AT91 pin configuration node is a node of a group of pins which can be
|
||||
used for a specific device or function. This node represents both mux and config
|
||||
of the pins in that group. The 'pins' selects the function mode(also named pin
|
||||
mode) this pin can work on and the 'config' configures various pad settings
|
||||
such as pull-up, multi drive, etc.
|
||||
|
||||
Required properties for iomux controller:
|
||||
- compatible: "atmel,at91rm9200-pinctrl"
|
||||
- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
|
||||
configured in this periph mode. All the periph and bank need to be describe.
|
||||
|
||||
How to create such array:
|
||||
|
||||
Each column will represent the possible peripheral of the pinctrl
|
||||
Each line will represent a pio bank
|
||||
|
||||
Take an example on the 9260
|
||||
Peripheral: 2 ( A and B)
|
||||
Bank: 3 (A, B and C)
|
||||
=>
|
||||
|
||||
/* A B */
|
||||
0xffffffff 0xffc00c3b /* pioA */
|
||||
0xffffffff 0x7fff3ccf /* pioB */
|
||||
0xffffffff 0x007fffff /* pioC */
|
||||
|
||||
For each peripheral/bank we will descibe in a u32 if a pin can can be
|
||||
configured in it by putting 1 to the pin bit (1 << pin)
|
||||
|
||||
Let's take the pioA on peripheral B
|
||||
From the datasheet Table 10-2.

|

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

|
||||
|
||||
pinctrl@fffff400 {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <1>;
|
