I can't see users of it.
on v7.1-rc1
$ git grep opb-hwicap
Documentation/devicetree/bindings/xilinx.txt:126:
"xlnx,opb-hwicap-1.00.b".
drivers/char/xilinx_hwicap/xilinx_hwicap.c:733: { .compatible =
"xlnx,opb-hwicap-1.00.b", .data = &buffer_icap_config},
$ git grep xps-hwicap
Documentation/devicetree/bindings/xilinx.txt:125: - compatible :
should contain "xlnx,xps-hwicap-1.00.a" or
drivers/char/xilinx_hwicap/xilinx_hwicap.c:734: { .compatible =
"xlnx,xps-hwicap-1.00.a", .data = &fifo_icap_config},
Thanks,
Michal
