 NVIDIA Tegra Power Management Controller (PMC)
 
-Properties:
+Required properties:
 - name : Should be pmc
 - compatible : Should contain "nvidia,tegra<chip>-pmc".
 - reg : Offset and length of the register set for the device
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Must include the following entries:
+  "pclk" (The Tegra clock of that name),
+  "clk32k_in" (The 32KHz clock input to Tegra).
+
+Optional properties:
 - nvidia,invert-interrupt : If present, inverts the PMU interrupt signal.
   The PMU is an external Power Management Unit, whose interrupt output
   signal is fed into the PMC. This signal is optionally inverted, and then
