power/fsl: add MDIO dt binding for FMan
This binding is for FMan MDIO, it covers FMan v2 & FMan v3. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> [scottwood@freescale.com: mark interrupts required only for external] Signed-off-by: Scott Wood <scottwood@freescale.com>

FMan MDIO Node
|
||||
|
||||
DESCRIPTION
|
||||
|
||||
The MDIO is a bus to which the PHY devices are connected.
|
||||
|
||||
PROPERTIES
|
||||
|
||||
- compatible
|
||||
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
|
||||
FMan v3.
|
||||
|
||||
- reg
|
||||
Usage: required
|
||||
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.
|
||||
|
||||
EXAMPLE
|
||||
|
||||
Example for FMan v2 external MDIO:
|
||||
|
||||
mdio@f1000 {
|
||||
compatible = "fsl,fman-xmdio";
|
||||
reg = <0xf1000 0x1000>;
|
||||
interrupts = <101 2 0 0>;
|
||||
};
|
||||
|
||||
Example for FMan v3 internal MDIO:
|
||||
|
||||
mdio@f1000 {
|
||||
compatible = "fsl,fman-memac-mdio";
|
||||
reg = <0xf1000 0x1000>;
|
||||
fsl,fman-internal-mdio;
|
||||
};
