There's already an ABI documentation for this driver. See: https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/tree/drivers/staging/iio/Documentation/sysfs-bus-iio-impedance-analyzer-ad5933 Apologies for not mentioning this sooner. Could you check for other references for ad5933 in the kernel (in staging) ? I don't think I missed other stuff, but it's good to check. > > Signed-off-by: Marcelo Schmitt <marcelo.schmi...@gmail.com> > --- > .../ABI/testing/sysfs-bus-iio-ad5933 | 39 +++++++++++++++++++ > 1 file changed, 39 insertions(+) > create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-ad5933 > > diff --git a/Documentation/ABI/testing/sysfs-bus-iio-ad5933 > b/Documentation/ABI/testing/sysfs-bus-iio-ad5933 > new file mode 100644 > index 000000000000..8a60dd178b1f > --- /dev/null > +++ b/Documentation/ABI/testing/sysfs-bus-iio-ad5933 > @@ -0,0 +1,39 @@ > +What:/sys/bus/iio/devices/iio:deviceX/out_voltage0_freq_start > +Date: March 2019 > +KernelVersion: Kernel 4.19 > +Contact: linux-...@vger.kernel.org > +Description: > + The start frequency.
