| description: | |
| 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. |

| 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)>; |
