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 16 17Example: 18 19 20board { 21 compatible = "gdsys,board_gazerbeam"; 22 csb = <&board_soc>; 23 serdes = <&SERDES>; 24 rxaui0 = <&RXAUI0>; 25 rxaui1 = <&RXAUI1>; 26 rxaui2 = <&RXAUI2>; 27 rxaui3 = <&RXAUI3>; 28 fpga0 = <&FPGA0>; 29 fpga1 = <&FPGA1>; 30 ioep0 = <&IOEP0>; 31 ioep1 = <&IOEP1>; 32 33 ver-gpios = <&PPCPCA 12 0 34 &PPCPCA 13 0 35 &PPCPCA 14 0 36 &PPCPCA 15 0>; 37 38 /* MC2/SC-Board */ 39 var-gpios-mc2 = <&GPIO_VB0 0 0 /* VAR-MC_SC */ 40 &GPIO_VB0 11 0>; /* VAR-CON */ 41 /* MC4-Board */ 42 var-gpios-mc4 = <&GPIO_VB1 0 0 /* VAR-MC_SC */ 43 &GPIO_VB1 11 0>; /* VAR-CON */ 44 45 reset-gpios = <&gpio0 1 0 &gpio0 2 1>; 46}; 47
