+== Clock Controller ==
+The clock controller is a logical abstraction of Zynq's clock tree. It reads
+required input clock frequencies from the devicetree and acts as clock provider
+for all clock consumers of PS clocks.
+
+Required properties:
+ - #clock-cells : Must be 1
+ - compatible : "xlnx,ps7-clkc"
+ - ps-clk-frequency : Frequency of the oscillator providing ps_clk in HZ
+		      (usually 33 MHz oscillators are used for Zynq platforms)
+ - clock-output-names : List of strings used to name the clock outputs. Shall be
+			a list of the outputs given below.
+
+Optional properties:
+ - clocks : as described in the clock bindings
+ - clock-names : as described in the clock bindings
+
+Clock inputs:
+The following strings are optional parameters to the 'clock-names' property in
+order to provide an optional (E)MIO clock source.
+ - swdt_ext_clk
+ - gem0_emio_clk
+ - gem1_emio_clk
+ - mio_clk_XX		# with XX = 00..53
+...
