Convert the common MDIO mux bindings to DT schema. Drop the example from mdio-mux.yaml as mdio-mux-gpio.yaml has the same one. Cc: "David S.

Properties for an MDIO bus multiplexer/switch controlled by GPIO pins.
|
||||
|
||||
This is a special case of a MDIO bus multiplexer. One or more GPIO
|
||||
lines are used to control which child bus is connected.
|
||||
|
||||
Required properties in addition to the generic multiplexer properties:

|
||||
- compatible : mdio-mux-gpio.
|
||||
- gpios : GPIO specifiers for each GPIO line. One or more must be specified.

/* The parent MDIO bus. */

Properties for an MDIO bus multiplexer controlled by a memory-mapped device
|
||||
|
||||
This is a special case of a MDIO bus multiplexer. A memory-mapped device,
|
||||
like an FPGA, is used to control which child bus is connected. The mdio-mux
|
||||
node must be a child of the memory-mapped device. The driver currently only
|
||||
supports devices with 8, 16 or 32-bit registers.
|
||||
|
||||
Required properties in addition to the generic multiplexer properties:
|
||||
|
||||
- compatible : string, must contain "mdio-mux-mmioreg"
|
||||
|
||||
- reg : integer, contains the offset of the register that controls the bus
|
||||
multiplexer. The size field in the 'reg' property is the size of
|
||||
register, and must therefore be 1, 2, or 4.
|
||||
|
||||
- mux-mask : integer, contains an eight-bit mask that specifies which
|
||||
bits in the register control the actual bus multiplexer. The
|
||||
'reg' property of each child mdio-mux node must be constrained by
|
||||
this mask.
|
||||
|
||||
Example:
|
||||
|
||||
The FPGA node defines a memory-mapped FPGA with a register space of 0x30 bytes.
|
||||
For the "EMI2" MDIO bus, register 9 (BRDCFG1) controls the mux on that bus.
|
||||
A bitmask of 0x6 means that bits 1 and 2 (bit 0 is lsb) are the bits on
|
||||
BRDCFG1 that control the actual mux.

||||

Properties for an MDIO bus multiplexer consumer device
|
||||
|
||||
This is a special case of MDIO mux when MDIO mux is defined as a consumer
|
||||
of a mux producer device. The mux producer can be of any type like mmio mux
|
||||
producer, gpio mux producer or generic register based mux producer.
|
||||
|
||||
Required properties in addition to the MDIO Bus multiplexer properties:
|
||||
|
||||
- compatible : should be "mmio-mux-multiplexer"
|
||||
- mux-controls : mux controller node to use for operating the mux
|
||||
- mdio-parent-bus : phandle to the parent MDIO bus.
|
||||

This is a special case of MDIO mux when MDIO mux is defined as a consumer
|
||||
of a mux producer device. The mux producer can be of any type like mmio mux
|
||||
producer, gpio mux producer or generic register based mux producer.

Common MDIO bus multiplexer/switch properties.
|
||||
|
||||
An MDIO bus multiplexer/switch will have several child busses that are
|
||||
numbered uniquely in a device dependent manner. The nodes for an MDIO
|
||||
bus multiplexer/switch will have one child node for each child bus.
|
||||
|
||||
Required properties:
|
||||
- #address-cells = <1>;
|
||||
- #size-cells = <0>;
|
||||
|
||||
Optional properties:
|
||||
- mdio-parent-bus : phandle to the parent MDIO bus.
|
||||
|
||||
- Other properties specific to the multiplexer/switch hardware.
|
||||
|
||||
Required properties for child nodes:
|
||||
- #address-cells = <1>;
|
||||
- #size-cells = <0>;
|
||||
- reg : The sub-bus number.
|
||||
|
||||
|
||||

|
||||
|
||||
/* The parent MDIO bus. */
