The AMS has two SYSMON blocks which are PL (Programmable Logic) SYSMON and PS (Processing System) SYSMON. All designs should have AMS registers, but PS and PL are optional. The AMS controller can work with only PS, only PL and both PS and PL configurations. Please specify registers according to your design. Devicetree should always have AMS module property. Providing PS & PL module is optional.
