Janine Hagemann 0f347a0096 net: phy: ti: Add binding for the CLK_OUT pin muxing
The DP83867 has a muxing option for the CLK_OUT pin. It is possible
to set CLK_OUT for different channels.
Create a binding to select a specific clock for CLK_OUT pin.

Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for
the CLK_OUT pin muxing option") of mainline linux kernel.

* Texas Instruments - dp83867 Giga bit ethernet phy
Required properties:
- reg - The ID number for the phy, usually a small integer
- ti,rx-internal-delay - RGMII Recieve Clock Delay - see dt-bindings/net/ti-dp83867.h
for applicable values
- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
for applicable values
- ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
for applicable values
- enet-phy-lane-swap - Indicates that PHY will swap the TX/RX lanes to
compensate for the board being designed with the lanes swapped.
- enet-phy-no-lane-swap - Indicates that PHY will disable swap of the
TX/RX lanes.
- ti,clk-output-sel - Clock output select - see dt-bindings/net/ti-dp83867.h
for applicable values
Default child nodes are standard Ethernet PHY device
nodes as described in doc/devicetree/bindings/net/ethernet.txt
Example:
ethernet-phy@0 {
reg = <0>;
ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
enet-phy-lane-no-swap;
ti,clk-output-sel = <DP83867_CLK_O_SEL_CHN_A_TCLK>;
};
