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@...fuse@...000/clock-names; echo
core
~ # hexdump -C /sys/firmware/devicetree/base/soc@...fuse@...000/clocks

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 ;)
