Lantiq XWAY SoC GPHY binding
|
||
|
|
============================
|
||
|
|
|
||
|
|
This binding describes a software-defined ethernet PHY, provided by the RCU
|
||
|
|
module on newer Lantiq XWAY SoCs (xRX200 and newer).
|
||
|
|
|
||
|
|
-------------------------------------------------------------------------------
|
||
|
|
Required properties:
|
||
|
|
- compatible : Should be one of
|
||
|
|
"lantiq,xrx200a1x-gphy"
|
||
|
|
"lantiq,xrx200a2x-gphy"
|
||
|
|
"lantiq,xrx300-gphy"
|
||
|
|
"lantiq,xrx330-gphy"
|
||
|
|
- reg : Addrress of the GPHY FW load address register
|
||
|
|
- resets : Must reference the RCU GPHY reset bit
|
||
|
|
- reset-names : One entry, value must be "gphy" or optional "gphy2"
|
||
|
|
- clocks : A reference to the (PMU) GPHY clock gate
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- lantiq,gphy-mode : GPHY_MODE_GE (default) or GPHY_MODE_FE as defined in
|
||
|
|
<dt-bindings/mips/lantiq_xway_gphy.h>
|
||
|
|
|
||
|
|
|
||
|
|
-------------------------------------------------------------------------------
|
||
|
|
Example for the GPHys on the xRX200 SoCs:
|
||
|
|
|
||
|
|
#include <dt-bindings/mips/lantiq_rcu_gphy.h>
|
||
|
|
gphy0: gphy@20 {
|
||
|
|
compatible = "lantiq,xrx200a2x-gphy";
|
||
|
|
reg = <0x20 0x4>;
|
||
|
|
|
||
|
|
resets = <&reset0 31 30>, <&reset1 7 7>;
|
||
|
|
reset-names = "gphy", "gphy2";
|
||
|
|
clocks = <&pmu0 XRX200_PMU_GATE_GPHY>;
|
||
|
|
lantiq,gphy-mode = <GPHY_MODE_GE>;
|
||
|
|
};
