| 2 | |
| 3 | This driver provides capabilities to access the gdsys Gazerbeam board's device |
| 4 | information. Furthermore, phandles to some internal devices are provided for |
| 5 | the board files. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible: should be "gdsys,board_gazerbeam" |
| 9 | - csb: phandle to the board's coherent system bus (CSB) device node |
| 10 | - rxaui[0-3]: phandles to the rxaui control device nodes |
| 11 | - fpga[0-1]: phandles to the board's gdsys FPGA device nodes |
| 12 | - ioep[0-1]: phandles to the board's IO endpoint device nodes |
| 13 | - ver-gpios: GPIO list to read the hardware version from |
| 14 | - var-gpios: GPIO list to read the hardware variant information from |
| 15 | - reset-gpios: GPIO list for the board's reset GPIOs |
| 16 | |
| 17 | Example: |
