+title: X-Powers AC200 mixed-signal IC
+
+maintainers:
+  - James Hilliard <james.hilliard1@gmail.com>
+
+description:
+  The AC200 is a mixed-signal companion IC containing audio, video, RTC and
+  Fast Ethernet PHY functions. Its control registers are accessed over I2C.
+
+properties:
+  compatible:
+    const: x-powers,ac200
+
+  reg:
+    maxItems: 1
+
+  clocks:
+    maxItems: 1
+    description:
+      AC200 input clock. When using the Ethernet PHY, its configured rate must
+      be 24 or 27 MHz, matching the rates encoded by the documented EPHY clock
+      selector.
