Description

Infineon Cat1 PWM

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.
