Still NAK, sorry. Please drop the clock/reset-names from the driver (use indices) and DTS. NAK means Not-acknowledge. Usually you should not send the same patch after getting NAK, because it looks like you ignore the comment. Best regards, Krzysztof

I'm currently in the state of moving and can't set up my hardware to test the changes. And I'm not willing to submit changes without testing. And with testing I really mean testing it against a running Crust firmware which touches the hwspinlock unit. If someone wants to change that, I'm happy to see it working out, but please do it properly. Just testing the locks in Linux only is not sufficient. If some directions are required, I still have my working repo up at Github: https://github.com/wgottwalt/sunxi_hwspinlock It may be a bit dated, but should be a good start. Greetings, Will
