+* HDLC
+
+Currently defined compatibles:
+- fsl,ucc-hdlc
+
+Properties for fsl,ucc-hdlc:
+- rx-clock-name
+- tx-clock-name
+ Usage: required
+ Value type: <string>
+ Definition : Must be "brg1"-"brg16" for internal clock source,
+ Must be "clk1"-"clk24" for external clock source.
+
+- fsl,tdm-interface
+ Usage: optional
+ Value type: <empty>
+ 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: <string>
+ Definition : Must be "none", "rsync_pin", "brg9-11" and "brg13-15".
+
+- fsl,tx-sync-clock
+ Usage: required
+ Value type: <string>
+ Definition : Must be "none", "tsync_pin", "brg9-11" and "brg13-15".
+
+- fsl,tdm-framer-type
+ Usage: required for tdm interface
+ Value type: <string>
+ 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: <u32>
+ Definition : number of TDM ID
+
+- fsl,tx-timeslot-mask
+- fsl,rx-timeslot-mask
+ Usage: required for tdm interface
+ Value type: <u32>
+ 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: <u32>
+ Definition : Must be 0,2,4...64. the number of TDM entry.
+
+- fsl,tdm-internal-loopback
+ usage: optional for tdm interface
+ value type: <empty>
+ 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 = <0xfffffffe>;
+ fsl,rx-timeslot-mask = <0xfffffffe>;
+ 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";
+ };
