   1 gdsys Gazerbeam board driver
   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
