Subject: [PATCH 0/4] Add support for ADMV8818

The ADMV8818-EP is a fully monolithic microwave integrated 
circuit (MMIC) that features a digitally selectable frequency of 
operation. The device features four independently controlled high-
pass filters (HPFs) and four independently controlled low-pass 
filters (LPFs) that span the 2 GHz to 18 GHz frequency range.

This patch series includes a proposal to add a subsection in the
IIO subsystem for filter drivers.

NOTE:
Currently depends on 64-bit architecture since the input
clock that server as RFIN should support values
in the range 2 GHz to 18 GHz.

We might need some scaling implementation in the clock
framework so that u64 types are supported when using 32-bit
architectures.
