KEBA PLCs use a PCIe FPGA to implement several functions in a common
way. This is a first step to include basic support for this FPGA.
Under drivers/misc the cp500 PCI driver is added. This drivers creates
platform devices for every function inside the FPGA. As a first step it
only creates platform devices for the I2C controllers.
The I2C controller driver is added under drivers/i2c/busses like all the
other I2C controller drivers.
This patches enable access to the EEPROMs and to the hardware monitoring
chip of KEBA PLCs.
