-== PLLs ==
-
-Used to describe the ARM_PLL, DDR_PLL, and IO_PLL.
+== 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 : shall be 0 (only one clock is output from this node)
-- compatible : "xlnx,zynq-pll"
-- reg : pair of u32 values, which are the address offsets within the SLCR
-        of the relevant PLL_CTRL register and PLL_CFG register respectively
-- clocks : phandle for parent clock.  should be the phandle for ps_clk
+ - #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:
-- clock-output-names : name of the output clock
-
-Example:
-	armpll: armpll {
-		#clock-cells = <0>;
-		compatible = "xlnx,zynq-pll";
-		clocks = <&ps_clk>;
-		reg = <0x100 0x110>;
-		clock-output-names = "armpll";
-	};

-== Peripheral clocks ==
+ - clocks : as described in the clock bindings
+ - clock-names : as described in the clock bindings
 
-Describes clock node for the SDIO, SMC, SPI, QSPI, and UART clocks.
+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
+...
 
-Required properties:
-- #clock-cells : shall be 1
-- compatible : "xlnx,zynq-periph-clock"
-- reg : a single u32 value, describing the offset within the SLCR where
-        the CLK_CTRL register is found for this peripheral
-- clocks : phandle for parent clocks.  should hold phandles for
-           the IO_PLL, ARM_PLL, and DDR_PLL in order
-- clock-output-names : names of the output clock(s).  For peripherals that have
-                       two output clocks (for example, the UART), two clocks
-                       should be listed.
