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.
