Commit ad7061ed74 ("doc: Move device tree bindings documentation to
doc/device-tree-bindings") moved all device tree binding documentation
to doc/device-tree-bindings directory.
The current U-Boot project still have two documentation directories:
- doc/
- Documentation/
Move all documentation and sphinx files to doc directory so all content
can be in a common place.

gdsys Gazerbeam board driver
|
|
|
|
This driver provides capabilities to access the gdsys Gazerbeam board's device
|
|
information. Furthermore, phandles to some internal devices are provided for
|
|
the board files.
|
|
|
|
Required properties:
|
|
- compatible: should be "gdsys,board_gazerbeam"
|
|
- csb: phandle to the board's coherent system bus (CSB) device node
|
|
- rxaui[0-3]: phandles to the rxaui control device nodes
|
|
- fpga[0-1]: phandles to the board's gdsys FPGA device nodes
|
|
- ioep[0-1]: phandles to the board's IO endpoint device nodes
|
|
- ver-gpios: GPIO list to read the hardware version from
|
|
- var-gpios: GPIO list to read the hardware variant information from
|
|
- reset-gpios: GPIO list for the board's reset GPIOs
|
|
|
|
Example:
|
|
|
|
|
|
board {
|
|
compatible = "gdsys,board_gazerbeam";
|
|
csb = <&board_soc>;
|

|

rxaui1 = <&RXAUI1>;

rxaui2 = <&RXAUI2>;
|
|
rxaui3 = <&RXAUI3>;
|
|
fpga0 = <&FPGA0>;
|
|
fpga1 = <&FPGA1>;
|
|
ioep0 = <&IOEP0>;
|

ioep1 = <&IOEP1>;
