Changes for v2
- use ucc-hdlc instead of ucc_hdlc
- add more information to properties.
Changes for v3
- use fsl,tx-timeslot-mask instead of fsl,tx-timeslot 
- use fsl,rx-timeslot-mask instead of fsl,rx-timeslot 
- add more info

+* HDLC
+
+Currently defined compatibles:
+- fsl,ucc-hdlc
+
+Properties for fsl,ucc-hdlc:
+- rx-clock-name
+- tx-clock-name
+   Usage: required
+   Value type: 
+   Definition : Must be "brg1"-"brg16" for internal clock source,
+Must be "clk1"-"clk24" for external clock source.
+
+- fsl,tdm-interface
+   Usage: optional
+   Value type: 
+   Definition : Specify that hdlc is based on tdm-interface
+
+The property below is dependent on fsl,tdm-interface:
+- fsl,rx-sync-clock
+   Usage: required
+   Value type: 
+   Definition : Must be "none", "rsync_pin", "brg9-11" and "brg13-15".
+
+- fsl,tx-sync-clock
+   Usage: required
+   Value type: 
+   Definition : Must be "none", "tsync_pin", "brg9-11" and "brg13-15".
+
+- fsl,tdm-framer-type
+   Usage: required for tdm interface
+   Value type: 
+   Definition : "e1" or "t1".Now e1 and t1 are used, other framer types
+are not supported.
+
+- fsl,tdm-id
+   Usage: required for tdm interface
+   Value type: 
+   Definition : number of TDM ID
+
+- fsl,tx-timeslot-mask
+- fsl,rx-timeslot-mask
+   Usage: required for tdm interface
+   Value type: 
+   Definition : time slot mask for TDM operation. Indicates which time
+slots used for transmitting and receiving.
+
+- fsl,siram-entry-id
+   Usage: required for tdm interface
+   Value type: 
+   Definition : Must be 0,2,4...64. the number of TDM entry.
+
+- fsl,tdm-internal-loopback
+   usage: optional for tdm interface
+   value type: 
+   Definition : Internal loopback connecting on TDM layer.
+
+Example for tdm interface:
+
+   ucc@2000 {
+   compatible = "fsl,ucc-hdlc";
+   rx-clock-name = "clk8";
+   tx-clock-name = "clk9";
+   fsl,rx-sync-clock = "rsync_pin";
+   fsl,tx-sync-clock = "tsync_pin";
+   fsl,tx-timeslot-mask = <0xfffe>;
+   fsl,rx-timeslot-mask = <0xfffe>;
+   fsl,tdm-framer-type = "e1";
+   fsl,tdm-id = <0>;
+   fsl,siram-entry-id = <0>;
+   fsl,tdm-interface;
+   };
+
+Example for hdlc without tdm interface:
+
+   ucc@2000 {
+   compatible = "fsl,ucc-hdlc";
+   rx-clock-name = "brg1";
+   tx-clock-name = "brg1";
+   };
