From: Angelo Dureghello Date: Fri, 6 Jun 2025 14:19:16 +0000 (+0200) Subject: Documentation: ABI: IIO: add new convdelay documentation X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c86b60189f35be0657166381a6d269990cd7190a;p=users%2Fhch%2Fmisc.git Documentation: ABI: IIO: add new convdelay documentation Add new IIO "convdelay" documentation. The ad7606 implements a phase calibation feature, in nanoseconds. Being this a time delay, using the convdelay suffix.
