+description: |
+ A Moortec PVT (Process, Voltage, Temperature) monitoring logic design can
+ include many different units.
+ Such a design will usually consists of several Moortec's embedded analog IPs,
+ and a single Moortec controller (mr75203) to configure and control the IPs.
+
+ Some of the Moortec's analog hard IPs that can be used in a design:
+ *) Temperature Sensor (TS) - used to monitor core temperature (e.g. mr74137).
+ *) Voltage Monitor (VM) - used to monitor voltage levels (e.g. mr74138).
+ *) Process Detector (PD) - used to assess silicon speed (e.g. mr74139).
+ *) Delay Chain - ring oscillator connected to the PD, used to measure IO
+ based transistors (e.g. mr76008 ring oscillator at 1.1V, mr76007 ring
+ oscillator at 1.8V).
+ *) Pre Scaler - provides divide-by-X scaling of input voltage, which can then
+ be presented for VM for measurement within its range (e.g. mr76006 -
+ divide by 2 pre-scaler).
+
+ TS, VM & PD also include a digital interface, which consists of configuration
+ inputs and measurement outputs.
+
+ Some of the units have number of series, each series can have slightly
+ different characteristics.
+
+ The mr75203 binding describes configuration for the controller unit, but also
+ for some of the analog IPs.
