Use generic device property accessors.
Make the clock optional assuming it's managed by firmware.

On which hardware has this been tested?

This was tested on nexthop.ai data-center NH-4010 switch with Xilinx based FPGA.

The following ACPI ASL fragment was used to describe the device:

             Device (I2C2) {
                 Name (_HID, "PRP0001")
                 Name (_CRS, ResourceTemplate () {
                     Memory32Fixed (ReadWrite, 0x80a40400, 0x00000200)
                     GpioInt (Level, ActiveHigh, Exclusive, PullNone, 0,
                         "\\_SB.PCI0.GPP5.FPGA") { 10 }
                 })
                 Name (_DSD, Package () {
                     ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
                     Package () {
                        Package () { "compatible", "xlnx,axi-iic-2.1" },
                        Package () { "single-master", 1 },
                     }
                 })
             }

can you share more details about cpu and bootflow?

Thanks,
