Right, that appears to work! ~ # ls -d /sys/bus/platform/drivers/qcom,qfprom/*.efuse /sys/bus/platform/drivers/qcom,qfprom/784000.efuse ~ # cat /sys/firmware/devicetree/base/soc@0/efuse@784000/clock-names; echo core ~ # hexdump -C /sys/firmware/devicetree/base/soc@0/efuse@784000/clocks 00000000 00 00 00 03 00 00 00 b8 |........| 00000008 Never tested this case before, but since it appears to work with the patched qfprom driver (other patch in this series) I think we can drop this patch. Will also have to adjust some other patches in my local tree then that do similar things ;) Regards Luca > > Konrad

On non-ChromeOS boards the clock cannot be touched, so move it in the chrome-common dtsi which is the only place where it's needed.
