-* Cadence Quad SPI controller
-
-Required properties:
-- compatible : should be one of the following:
-	Generic default - "cdns,qspi-nor".
-	For TI 66AK2G SoC - "ti,k2g-qspi", "cdns,qspi-nor".
-	For TI AM654 SoC  - "ti,am654-ospi", "cdns,qspi-nor".
-- reg : Contains two entries, each of which is a tuple consisting of a
-	physical address and length. The first entry is the address and
-	length of the controller register set. The second entry is the
-	address and length of the QSPI Controller data area.
-- interrupts : Unit interrupt specifier for the controller interrupt.
-- clocks : phandle to the Quad SPI clock.
-- cdns,fifo-depth : Size of the data FIFO in words.
-- cdns,fifo-width : Bus width of the data FIFO in bytes.
-- cdns,trigger-address : 32-bit indirect AHB trigger address.
-
-Optional properties:
-- cdns,is-decoded-cs : Flag to indicate whether decoder is used or not.
-- cdns,rclk-en : Flag to indicate that QSPI return clock is used to latch
-  the read data rather than the QSPI clock. Make sure that QSPI return
-  clock is populated on the board before using this property.
-
-Optional subnodes:
-Subnodes of the Cadence Quad SPI controller are spi slave nodes with additional
-custom properties:
-- cdns,read-delay : Delay for read capture logic, in clock cycles
-- cdns,tshsl-ns : Delay in nanoseconds for the length that the master
-                  mode chip select outputs are de-asserted between
-		  transactions.
-- cdns,tsd2d-ns : Delay in nanoseconds between one chip select being
-                  de-activated and the activation of another.
-- cdns,tchsh-ns : Delay in nanoseconds between last bit of current
-                  transaction and deasserting the device chip select
-		  (qspi_n_ss_out).
-- cdns,tslch-ns : Delay in nanoseconds between setting qspi_n_ss_out low
-                  and first bit transfer.
-- resets	: Must contain an entry for each entry in reset-names.
-		  See ../reset/reset.txt for details.
-- reset-names	: Must include either "qspi" and/or "qspi-ocp".
-
-Example:
-
-	qspi: spi@ff705000 {
-		compatible = "cdns,qspi-nor";
-		#address-cells = <1>;
-		#size-cells = <0>;
-		reg = <0xff705000 0x1000>,
-		      <0xffa00000 0x1000>;
-		interrupts = <0 151 4>;
-		clocks = <&qspi_clk>;
-		cdns,is-decoded-cs;
-		cdns,fifo-depth = <128>;
-		cdns,fifo-width = <4>;
-		cdns,trigger-address = <0x00000000>;
-		resets = <&rst QSPI_RESET>, <&rst QSPI_OCP_RESET>;
-		reset-names = "qspi", "qspi-ocp";
-
-		flash0: n25q00@0 {
-			...
-			cdns,read-delay = <4>;
-			cdns,tshsl-ns = <50>;
-			cdns,tsd2d-ns = <50>;
-			cdns,tchsh-ns = <4>;
-			cdns,tslch-ns = <4>;
-		};
