  1. gdsys Gazerbeam board driver
  2. This driver provides capabilities to access the gdsys Gazerbeam board's device
  3. information. Furthermore, phandles to some internal devices are provided for
  4. the board files.
  5. Required properties:
  6. - compatible: should be "gdsys,board_gazerbeam"
  7. - csb: phandle to the board's coherent system bus (CSB) device node
  8. - rxaui[0-3]: phandles to the rxaui control device nodes
  9. - fpga[0-1]: phandles to the board's gdsys FPGA device nodes
  10. - ioep[0-1]: phandles to the board's IO endpoint device nodes
  11. - ver-gpios: GPIO list to read the hardware version from
  12. - var-gpios: GPIO list to read the hardware variant information from
  13. - reset-gpios: GPIO list for the board's reset GPIOs
  14. Example:
  15. board {
  16. compatible = "gdsys,board_gazerbeam";
  17. csb = <&board_soc>;
  18. serdes = <&SERDES>;
  19. rxaui0 = <&RXAUI0>;
  20. rxaui1 = <&RXAUI1>;
  21. rxaui2 = <&RXAUI2>;
  22. rxaui3 = <&RXAUI3>;
  23. fpga0 = <&FPGA0>;
  24. fpga1 = <&FPGA1>;
  25. ioep0 = <&IOEP0>;
  26. ioep1 = <&IOEP1>;
  27. ver-gpios = <&PPCPCA 12 0
  28. &PPCPCA 13 0
  29. &PPCPCA 14 0
  30. &PPCPCA 15 0>;
  31. /* MC2/SC-Board */
  32. var-gpios-mc2 = <&GPIO_VB0 0 0 /* VAR-MC_SC */
  33. &GPIO_VB0 11 0>; /* VAR-CON */
  34. /* MC4-Board */
  35. var-gpios-mc4 = <&GPIO_VB1 0 0 /* VAR-MC_SC */
  36. &GPIO_VB1 11 0>; /* VAR-CON */
  37. reset-gpios = <&gpio0 1 0 &gpio0 2 1>;
  38. };
