gdsys Gazerbeam sysinfo driver
This driver provides capabilities to access the gdsys Gazerbeam board's device
information. Furthermore, phandles to some internal devices are provided for
the board files.
Required properties:
- compatible: should be "gdsys,sysinfo-gazerbeam"
- csb: phandle to the board's coherent system bus (CSB) device node
- rxaui[0-3]: phandles to the rxaui control device nodes
- fpga[0-1]: phandles to the board's gdsys FPGA device nodes
- ioep[0-1]: phandles to the board's IO endpoint device nodes
- ver-gpios: GPIO list to read the hardware version from
- var-gpios: GPIO list to read the hardware variant information from
- reset-gpios: GPIO list for the board's reset GPIOs
Example:
sysinfo {
compatible = "gdsys,sysinfo-gazerbeam";
csb = <&board_soc>;
serdes = <&SERDES>;
rxaui0 = <&RXAUI0>;
rxaui1 = <&RXAUI1>;
rxaui2 = <&RXAUI2>;
rxaui3 = <&RXAUI3>;
fpga0 = <&FPGA0>;
fpga1 = <&FPGA1>;
ioep0 = <&IOEP0>;
ioep1 = <&IOEP1>;
ver-gpios = <&PPCPCA 12 0
&PPCPCA 13 0
&PPCPCA 14 0
&PPCPCA 15 0>;
/* MC2/SC-Board */
var-gpios-mc2 = <&GPIO_VB0 0 0 /* VAR-MC_SC */
&GPIO_VB0 11 0>; /* VAR-CON */
/* MC4-Board */
var-gpios-mc4 = <&GPIO_VB1 0 0 /* VAR-MC_SC */
&GPIO_VB1 11 0>; /* VAR-CON */
reset-gpios = <&gpio0 1 0 &gpio0 2 1>;
};
