Convert to new API.
Fix-up out of staging includes.
Removed pll_locked attribute.
Changes since V2:

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_resolution

|
|
Description:
|
|
Stores channel Y frequency resolution/channel spacing in Hz.
|
|
The value given directly influences the MODULUS used by
|
|
the fractional-N PLL. It is assumed that the algorithm
|
|
that is used to compute the various dividers, is able to
|
|
generate proper values for multiples of channel spacing.

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency
|
|
KernelVersion: 3.4.0
|
|
Contact: linux-iio@vger.kernel.org
|
|
Description:
|
|
Sets channel Y REFin frequency in Hz. In some clock chained
|
|
applications, the reference frequency used by the PLL may
|
|
change during runtime. This attribute allows the user to
|
|
adjust the reference frequency accordingly.
|
|
The value written has no effect until out_altvoltageY_frequency
|
|
is updated. Consider to use out_altvoltageY_powerdown to power
|
|
down the PLL and it's RFOut buffers during REFin changes.
