Ah, good point. This patch was initially written before the Intel stuff was added. Will update. Apologies for the mis-formatted reply/email; will need to include my Gmail account to reply neater here. > Tom > + ADI_AXI_FPGA_TECH_UNKNOWN = 0, > + ADI_AXI_FPGA_TECH_SERIES7, > + ADI_AXI_FPGA_TECH_ULTRASCALE, > + ADI_AXI_FPGA_TECH_ULTRASCALE_PLUS, > +}; > + > +enum adi_axi_fpga_family { > + ADI_AXI_FPGA_FAMILY_UNKNOWN = 0, > + ADI_AXI_FPGA_FAMILY_ARTIX, > + ADI_AXI_FPGA_FAMILY_KINTEX, > + ADI_AXI_FPGA_FAMILY_VIRTEX, > + ADI_AXI_FPGA_FAMILY_ZYNQ, > +}; > + > +enum adi_axi_fpga_speed_grade { > + ADI_AXI_FPGA_SPEED_UNKNOWN = 0, > + ADI_AXI_FPGA_SPEED_1 = 10, > + ADI_AXI_FPGA_SPEED_1L = 11, > + ADI_AXI_FPGA_SPEED_1H = 12, > + ADI_AXI_FPGA_SPEED_1HV = 13, > + ADI_AXI_FPGA_SPEED_1LV = 14, > + ADI_AXI_FPGA_SPEED_2 = 20, > + ADI_AXI_FPGA_SPEED_2L = 21, > + ADI_AXI_FPGA_SPEED_2LV = 22, > + ADI_AXI_FPGA_SPEED_3 = 30, > +}; > + > #endif /* ADI_AXI_COMMON_H_ */
