The original driver is uploaded by Jianqun.
Here is his patchs:

Jianqun, nevermind!
I check-pick it and re-upload the driver for the upstream.
Tested by on minnie board.(kernel-4.1-rc8)
cd /sys/devices/platform/ffb40000.efuse
localhost ffb40000.efuse # cat cpu_leakage_show
The results:

Changes in v2:
- Change the document decription.
- Move the efuse driver into driver/soc/vendor.
- update the efuse driver.
- Add the dts node on RK3288.

i want to mention that there is a upcoming new framework suitable for
efuse drivers:

Unfortunately i don't know the current development state.

Currently this framework is used by atleast 3 drivers(qcom-tsens, qcom-cpr, begel-bone-cape manager) which are still floating in the mailing list.

I was hoping that these 3 users would getback with tested-by.. which did not happen for last 3-4 weeks.

I would appreciate, If you could try framework too, and let me know.

I will do that...

At the moment, I don't know how to use this framework.
I need some time to dig it, I'm happy if you some reference(driver or document).

I added two of wrappers on top of v5 at:

I think I should request Mark to take the framework.
