Description
***********
.. code-block:: none
TI SimpleLink CC13xx / CC26xx pinctrl node.
Device pin configuration should be placed in the child nodes of this node.
Populate the 'pinmux' field with a pair consisting of a pin number and its IO
functions.
The node has the 'pinctrl' node label set in your SoC's devicetree,
so you can modify it like this:
&pinctrl {
/* your modifications go here */
};
All device pin configurations should be placed in child nodes of the
'pinctrl' node, as in the i2c0 example shown at the end.
Here is a list of
supported standard pin properties:
- bias-disable: Disable pull-up/down.
- bias-pull-down: Enable pull-down resistor.
- bias-pull-up: Enable pull-up resistor.
- drive-open-drain: Output driver is open-drain.
- drive-open-drain: Output driver is open-source.
- input-enable: enable input.
- input-schmitt-enable: enable input schmitt circuit.
An example for CC13XX family, include the chip level pinctrl
DTSI file in the board level DTS:
#include
We want to configure the I2C pins to open drain, with pullup enabled
and input enabled.
To change a pin's pinctrl default properties add a reference to the
pin in the board's DTS file and set the properties.
&i2c0 {
pinctrl-0 = <&i2c0_scl_default &i2c0_sda_default>;
pinctrl-1 = <&i2c0_scl_sleep &i2c0_sda_sleep>;
pinctrl-names = "default", "sleep";
}
The i2c0_scl_default corresponds to the following in the board dts file:
&pinctrl {
i2c0_scl_default: i2c0_scl_default {
pinmux = <4 IOC_PORT_MCU_I2C_MSSCL>;
bias-pull-up;
drive-open-drain;
input-enable;
};
};

Top level properties
====================
These property descriptions apply to "ti,cc13xx-cc26xx-pinctrl"
nodes themselves. This page also describes child node
properties in the following sections.
.. tabs::
.. group-tab:: Node specific properties
Properties not inherited from the base binding file.
(None)
.. group-tab:: Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
.. group-tab:: Base properties
Properties inherited from the base binding file, which defines
common properties that may be set on many nodes. Not all of these
may apply to the "ti,cc13xx-cc26xx-pinctrl" compatible.

When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
