Simon Glass3a8ee3d2020-11-05 06:32:05 -07001gdsys Gazerbeam sysinfo driver
Mario Six6238ae42018-07-31 11:44:12 +02002
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.

7Required properties:
Simon Glass3a8ee3d2020-11-05 06:32:05 -07008- compatible: should be "gdsys,sysinfo-gazerbeam"
Mario Six6238ae42018-07-31 11:44:12 +02009- 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
