This series adds support for PWM capture devices within IIO and adds a TI ECAP IIO driver.
PWM capture devices are supported using a new IIO "pulse" channel type.
The IIO ECAP driver implements interrupt driven triggered buffer capture only as raw sample reads are not applicable to this hardware. Initially, the driver supports a single pulse width measurement with configurable polarity. The ECAP hardware can support measurement of a complete period and duty cycle but this is not yet implemented.
Matt Porter (5): iio: add support for pulse width capture devices iio: pulse: add TI ECAP driver iio: enable selection and build of pulse drivers pwm: enable TI PWMSS if the IIO tiecap driver is selected ARM: dts: AM33XX: Add ecap interrupt properties
