1gdsys Gazerbeam board driver
2
3This driver provides capabilities to access the gdsys Gazerbeam board's device
4information. Furthermore, phandles to some internal devices are provided for
5the board files.
6
7Required 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
