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:
|
||
|
|
|
||
|
|
|
||
|
|
