-Zynq SPI controller Device Tree Bindings
-----------------------------------------
+Cadence SPI controller Device Tree Bindings
+-------------------------------------------
 
 Required properties:
-- compatible           : Should be "xlnx,spi-zynq".
+- compatible           : Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6".
 - reg                  : Physical base address and size of SPI registers map.
-- status               : Status will be disabled in dtsi and enabled in required dts.
-- interrupt-parent     : Must be core interrupt controller.
 - interrupts           : Property with a value describing the interrupt
                          number.
-- clocks               : Clock phandles (see clock bindings for details).
+- interrupt-parent     : Must be core interrupt controller
 - clock-names          : List of input clock names - "ref_clk", "pclk"
                          (See clock bindings for details).
+- clocks               : Clock phandles (see clock bindings for details).
 - spi-max-frequency    : Maximum SPI clocking speed of device in Hz
 
+Optional properties:
+- num-cs               : Number of chip selects used.
+                         If a decoder is used, this will be the number of
+                         chip selects after the decoder.
+- is-decoded-cs                : Flag to indicate whether decoder is used or not.
+
