-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: should be one of the following. The generic compatible
-			"qcom,kpss-gcc" should also be included.
-			"qcom,kpss-gcc-ipq8064", "qcom,kpss-gcc"
-			"qcom,kpss-gcc-apq8064", "qcom,kpss-gcc"

-- reg:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: base address and size of the register region
-
-- clocks:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: reference to the pll parents.
-
-- clock-names:
-	Usage: required
-	Value type: <stringlist>
-	Definition: must be "pll8_vote", "pxo".
-
-- clock-output-names:
-	Usage: required
-	Value type: <string>
-	Definition: Name of the output clock. Typically acpu_l2_aux indicating
-		    an L2 cache auxiliary clock.
