Changes since v1:
- Rebased to 3.14-rc1
- Renamed in_pulse_polarity to pulse_polarity
- Added ABI entries for pulse devices and 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 (6):
iio: add support for pulse width capture devices
iio: pulse: add TI ECAP driver
iio: enable selection and build of pulse drivers
iio: Add ABI docs for pulse capture devices
pwm: enable TI PWMSS if the IIO tiecap driver is selected
ARM: dts: AM33XX: Add ecap interrupt properties
