Subject: [PATCH 0/5] IIO pulse capture support for TI ECAP

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
