I had originally asked to not put it under include/linux/fpga, but alas, now it's here :) It never made much sense imho to drop it under linux/fpga just because it's a hardware implemented in an FPGA....

We can always move it. I don't remember about any discussion on this matter. Or maybe I wasn't included. Or maybe I have some severe case of amnesia or carelessness for omitting threads. I am terrible at following threads. Apologies for anything on my part. If you propose another location, I can spin-up a patch on it. These reg-definitions are common to all ADI HDL regs. Maybe more may come up as stuff gets upstreamed. The full-blown/internal version we have is: https://github.com/analogdevicesinc/linux/blob/master/include/linux/fpga/adi-axi-common.h It tries to define some things that are common between Intel, Xilinx and ADI IP cores across [these and hopefully other] FPGA boards. I'm not saying it's doing a good job of that at the moment. ¯\_(ツ)_/¯ Thanks Alex > > Cheers, > Moritz

The format for all ADI AXI IP cores is the same. i.e. 'major.minor.patch'. This patch adds the helper macros to be re-used in ADI AXI drivers. Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> --- include/linux/fpga/adi-axi-common.h | 4 ++++ 1 file changed, 4 insertions(+)
