#pwm-cells

int

Number of items to expect in a PWM
- channel of the timer used for PWM
- period to set in ns
- flags : combination of standard flags like PWM_POLARITY_NORMAL
  or specific flags like STM32_PWM_COMPLEMENTARY. As an example,
  the following complementary PWMs(CH2&CH2N) are shown below.
    <&pwm1 2 100 (PWM_POLARITY_NORMAL)>;
    <&pwm1 2 100 (PWM_POLARITY_NORMAL | STM32_PWM_COMPLEMENTARY)>;

This property is required.

Constant value: 3

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

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.

pinctrl-names

string-array

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

This property is required.

four-channel-capture-support

boolean

Add support to capture on four channels. This is less accurate than
the default 2 channel support because the counter is reset by
interrupt instead of slave-mode controller. This option can also
be used as alternative for timers that does not support slave mode.
