Convert binding doc newwork.txt to yaml format.
HDLC part:
- Convert to "fsl,ucc-hdlc.yaml".
- Add missed reg and interrupt property.
- Update example to pass build.
ethernet part:
- Convert to net/fsl,cpm-enet.yaml
- Add 0x in example, which should be hex value
- Add ref to ethernet-controller.yaml
mdio part:
- Convert to net/fsl,cpm-mdio.yaml
- Add 0x in example, which should be hex value
- Add ref to mdio.yaml

Convert binding doc newwork.txt to yaml format.
HDLC part:
- Convert to "fsl,ucc-hdlc.yaml".
- Add missed reg and interrupt property.
- Update example to pass build.
ethernet part:
- Convert to net/fsl,cpm-enet.yaml
- Add 0x in example, which should be hex value
- Add ref to ethernet-controller.yaml
mdio part:
- Convert to net/fsl,cpm-mdio.yaml
- Add 0x in example, which should be hex value
- Add ref to mdio.yaml

-* MDIO
-
-Currently defined compatibles:
-fsl,pq1-fec-mdio (reg is same as first resource of FEC device)
-fsl,cpm2-mdio-bitbang (reg is port C registers)
-
-Properties for fsl,cpm2-mdio-bitbang:
-fsl,mdio-pin : pin of port C controlling mdio data
-fsl,mdc-pin : pin of port C controlling mdio clock
-

-* 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.
-- fsl,hmask
- usage: optional
- Value type: <u16>
- Definition: HDLC address recognition. Set to zero to disable
- address filtering of packets:
- fsl,hmask = /bits/ 16 <0x0000>;
-
-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";
- };
