|
|
Offline/Host command (O/H)
|
|
|
|
PROPERTIES
|

|
|
the FMan hardware port memory region (which is part of the
|
|
FMan memory map). The first 4 KB in the FMan hardware ports
|
|
memory region is used for what are called common registers.
|
|
The subsequent 63 4KB pages are allocated to the hardware
|
|
ports.
|

|
|
|
|

|
|
Usage: required
|
|
Value type: <stringlist>
|
|
Definition: A standard property.
|
|
Must include "fsl,fman-mdio" for 1 Gb/s MDIO from FMan v2.
|
|
Must include "fsl,fman-xmdio" for 10 Gb/s MDIO from FMan v2.
|
|
Must include "fsl,fman-memac-mdio" for 1/10 Gb/s MDIO from

Value type: <prop-encoded-array>
|
|
Definition: A standard property.
|
|
|
|
- bus-frequency
|
|
Usage: optional
|
|
Value type: <u32>
|
|
Definition: Specifies the external MDIO bus clock speed to
|
|
be used, if different from the standard 2.5 MHz.
|
|
This may be due to the standard speed being unsupported (e.g.
|
|
due to a hardware problem), or to advertise that all relevant
|
|
components in the system support a faster speed.
|
|
|
|
- interrupts
|
|
Usage: required for external MDIO
|
|
Value type: <prop-encoded-array>
|
|
Definition: Event interrupt of external MDIO controller.
|
|
|
|
- fsl,fman-internal-mdio
|
|
Usage: required for internal MDIO
|
|
Value type: boolean
|
|
Definition: Fman has internal MDIO for internal PCS(Physical
|
|
Coding Sublayer) PHYs and external MDIO for external PHYs.
|
|
The settings and programming routines for internal/external
|
|
MDIO are different. Must be included for internal MDIO.
|
|
|
|
For internal PHY device on internal mdio bus, a PHY node should be created.
|
|
See the definition of the PHY node in booting-without-of.txt for an
|
|
example of how to define a PHY (Internal PHY has no interrupt line).
|
|
- For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
|
|
- For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY,
|
|
PCS PHY addr must be '0'.
|
|
|
