infineon,cat1-pwm

Vendor: Infineon Technologies

Note

An implementation of a driver matching this compatible is available in drivers/pwm/pwm_ifx_cat1.c.

Description

Infineon Cat1 PWM

Properties

Node specific properties

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

 
PORT pin configuration for the PWM signal.
We expect that the phandles will reference pinctrl nodes. These
nodes will have a nodelabel that matches the Infineon SoC Pinctrl
defines and have following
format: p<port>_<pin>_<peripheral inst>_<signal>.

Examples:
  pinctrl-0 = <&p1_1_pwm0_0>;

This property is required.

pinctrl-names

string-array

 
Names for the provided states. The number of names needs to match the
number of states.

This property is required.

resolution

int

divider-type

int

 
Specifies which type of divider to use.
Defined by cy_en_divider_types_t in cy_sysclk.h.

This property is required.

divider-sel

int

 
Specifies which divider of the selected type to configure.

This property is required.

divider-val

int

 
Causes integer division of (divider value + 1), or division by 1 to 256
(8-bit divider) or 1 to 65536 (16-bit divider).

This property is required.

#pwm-cells

int

 
Number of items to expect in a PWM
- channel of the timer used for PWM (not used)
- period to set in ns
- flags: standard flags like PWM_POLARITY_NORMAL

This property is required.

Constant value: 3

pinctrl-1

phandles

 
Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

 
Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

 
Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

 
Pin configuration/s for the fifth state. See pinctrl-0.

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

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 “infineon,cat1-pwm” compatible.
