||
|
|
|
||
|
|

|
||
|
|
- reg: should contain the comphy register location and length.
|
||
|
|
- #address-cells: should be 1.
|
||
|
|
- #size-cells: should be 0.
|
||
|
|
|
||
|

A sub-node is required for each comphy lane provided by the comphy.

||
|
|
|
||
|
|
- reg: comphy lane number.
|
||
|
|
- #phy-cells : from the generic phy bindings, must be 1. Defines the
|
||
|

|
|
|
||
|
|
comphy: phy@18300 {

#address-cells = <1>;
|
||

|
|
cpm_comphy0: phy@0 {
|
||
|
|
reg = <0>;
|
||
|
|
#phy-cells = <1>;
|
||
|
|
};
|
||
|
|
|

|
|
cpm_comphy1: phy@1 {
|
||
|
|
reg = <1>;
