Here it is. https://github.com/Xilinx/linux-xlnx/blob/master/drivers/fpga/xilinx-pr-decoupler.c Your clk handling is better and my enable_show is better. You shouldn't rely on setting status before. It is better to read that reg again. The reason is you can connect status signal from one PR decoupler to decouple input which can change status There is another topic I wanted to open in connection to this. There should be gpio based bridge because this pr decoupler can be without axi interface and for that gpio driver would be useful.
