Hi,

I want to create a linux device driver for a FPGA connect in IFC. I have found a device that is connected in the original T2080RDB. I can see in the device tree:

Boardctrl -> board-control@2,0 -> fsl,t2080-cpld

I would like to know where the driver relate with this device is.

Best regards.

There is no dedicated driver.

The CPLD physical base address is 0xF_FFDF0000 and its registers could be accessed after obtaining a virtual address by means of the ioremap().
