      1OMAP SSI controller bindings
      2
      3OMAP3's Synchronous Serial Interface (SSI) controller implements a
      4legacy variant of MIPI's High Speed Synchronous Serial Interface (HSI),
      5while the controller found inside OMAP4 is supposed to be fully compliant
      6with the HSI standard.
      7
      8Required properties:
      9- compatible:		Should include "ti,omap3-ssi" or "ti,omap4-hsi"
     10- reg-names:		Contains the values "sys" and "gdd" (in this order).
     11- reg:			Contains a matching register specifier for each entry
     12			in reg-names.
     13- interrupt-names:	Contains the value "gdd_mpu".
     14- interrupts: 		Contains matching interrupt information for each entry
     15			in interrupt-names.
     16- ranges:		Represents the bus address mapping between the main
     17			controller node and the child nodes below.
     18- clock-names:		Must include the following entries:
     19  "ssi_ssr_fck": The OMAP clock of that name
     20  "ssi_sst_fck": The OMAP clock of that name
     21  "ssi_ick": The OMAP clock of that name
     22- clocks:		Contains a matching clock specifier for each entry in
     23			clock-names.
     24- #address-cells:	Should be set to <1>
     25- #size-cells:		Should be set to <1>
     26
     27Each port is represented as a sub-node of the ti,omap3-ssi device.
     28
     29Required Port sub-node properties:
     30- compatible:		Should be set to the following value
     31			ti,omap3-ssi-port (applicable to OMAP34xx devices)
     32			ti,omap4-hsi-port (applicable to OMAP44xx devices)
     33- reg-names:		Contains the values "tx" and "rx" (in this order).
     34- reg:			Contains a matching register specifier for each entry
     35			in reg-names.
     36- interrupts:		Should contain interrupt specifiers for mpu interrupts
     37			0 and 1 (in this order).
     38- ti,ssi-cawake-gpio:	Defines which GPIO pin is used to signify CAWAKE
     39			events for the port. This is an optional board-specific
     40			property. If it's missing the port will not be
     41			enabled.
     42
     43Optional properties:
     44- ti,hwmods:		Shall contain TI interconnect module name if needed
     45			by the SoC
     46
