-* Freescale (Enhanced) Configurable Serial Peripheral Interface
-  (CSPI/eCSPI) for i.MX
-
-Required properties:
-- compatible :
-  - "fsl,imx1-cspi" for SPI compatible with the one integrated on i.MX1
-  - "fsl,imx21-cspi" for SPI compatible with the one integrated on i.MX21
-  - "fsl,imx27-cspi" for SPI compatible with the one integrated on i.MX27
-  - "fsl,imx31-cspi" for SPI compatible with the one integrated on i.MX31
-  - "fsl,imx35-cspi" for SPI compatible with the one integrated on i.MX35
-  - "fsl,imx51-ecspi" for SPI compatible with the one integrated on i.MX51
-  - "fsl,imx53-ecspi" for SPI compatible with the one integrated on i.MX53 and later Soc
-  - "fsl,imx8mq-ecspi" for SPI compatible with the one integrated on i.MX8MQ
-  - "fsl,imx8mm-ecspi" for SPI compatible with the one integrated on i.MX8MM
-  - "fsl,imx8mn-ecspi" for SPI compatible with the one integrated on i.MX8MN
-  - "fsl,imx8mp-ecspi" for SPI compatible with the one integrated on i.MX8MP
-- reg : Offset and length of the register set for the device
-- interrupts : Should contain CSPI/eCSPI interrupt
-- clocks : Clock specifiers for both ipg and per clocks.
-- clock-names : Clock names should include both "ipg" and "per"
-See the clock consumer binding,
-	Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Recommended properties:
-- cs-gpios : GPIOs to use as chip selects, see spi-bus.txt.  While the native chip
-select lines can be used, they appear to always generate a pulse between each
-word of a transfer.  Most use cases will require GPIO based chip selects to
-generate a valid transaction.
-
-Optional properties:
-- num-cs :  Number of total chip selects, see spi-bus.txt.
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names: DMA request names, if present, should include "tx" and "rx".
-- fsl,spi-rdy-drctl: Integer, representing the value of DRCTL, the register
-controlling the SPI_READY handling. Note that to enable the DRCTL consideration,
-the SPI_READY mode-flag needs to be set too.
-Valid values are: 0 (disabled), 1 (edge-triggered burst) and 2 (level-triggered burst).
-
-Obsolete properties:
-- fsl,spi-num-chipselects : Contains the number of the chipselect
-
-Example:
-
-ecspi@70010000 {
-	#address-cells = <1>;
-	#size-cells = <0>;
-	compatible = "fsl,imx51-ecspi";
-	reg = <0x70010000 0x4000>;
-	interrupts = <36>;
-	cs-gpios = <&gpio3 24 0>, /* GPIO3_24 */
-		   <&gpio3 25 0>; /* GPIO3_25 */
-	dmas = <&sdma 3 7 1>, <&sdma 4 7 2>;
-	dma-names = "rx", "tx";
-	fsl,spi-rdy-drctl = <1>;
