Hisilicon Fast Ethernet MAC controller
|
|
|
|
Required properties:
|
|
- compatible: should contain one of the following version strings:
|
|
* "hisilicon,hisi-femac-v1"
|
|
* "hisilicon,hisi-femac-v2"
|
|
and the soc string "hisilicon,hi3516cv300-femac".
|
|
- reg: specifies base physical address(s) and size of the device registers.
|
|
The first region is the MAC core register base and size.
|
|
The second region is the global MAC control register.
|
|
- interrupts: should contain the MAC interrupt.
|
|
- clocks: A phandle to the MAC main clock.
|
|
- resets: should contain the phandle to the MAC reset signal(required) and
|
|
the PHY reset signal(optional).
|
|
- reset-names: should contain the reset signal name "mac"(required)
|
|
and "phy"(optional).
|
|
- mac-address: see ethernet.txt [1].
|
|
- phy-mode: see ethernet.txt [1].
|
|
- phy-handle: see ethernet.txt [1].
|
|
- hisilicon,phy-reset-delays-us: triplet of delays if PHY reset signal given.
|
|
The 1st cell is reset pre-delay in micro seconds.
|
|
The 2nd cell is reset pulse in micro seconds.
|
|
The 3rd cell is reset post-delay in micro seconds.
