between SQ52210 and INA3221.

+description: |
+  The INA3221 is a three-channel, high-side current and bus voltage monitor.
+
+  The Silergy SQ52210 is a power monitor that extends the functionality of
+  the INA3221 by adding additional current registers, power registers, and
+  alert registers. These features are configured internally by the driver
+  and require no board-level device tree configuration.
