misc: keba: Add basic KEBA CP500 system FPGA support The KEBA CP500 system FPGA is a PCIe device, which consists of multiple IP cores. Every IP core has its own auxiliary driver. The cp500 driver registers an auxiliary device for each device and the corresponding drivers are loaded by the Linux driver infrastructure. Currently 3 variants of this device exists. Every variant has its own PCI device ID, which is used to determine the list of available IP cores. In this first version only the auxiliary device for the I2C controller is registered. Besides the auxiliary device registration some other basic functions of the FPGA are implemented; e.g, FPGA version sysfs file, keep FPGA configuration on reset sysfs file, error message for errors on the internal AXI bus of the FPGA.

help
This driver supports the KEBA CP500 system FPGA, which is used in
KEBA CP500 devices. It registers all sub devices present on the CP500
system FPGA as separate devices. A driver is needed for each sub
device.
This driver can also be built as a module. If so, the module will be
called cp500.
misc: keba: Add LAN9252 driver KEBA CP500 devices use the LAN9252 controller for EtherCAT communication. For a stable Ethernet link the PHY registers of the controller need to be configured correctly. This driver configures these PHY registers as required.
