Hi Stefan, Arnd,

i don't have a answer to this question, but how about changing fsl_ocotp driver
to driver/soc/mxs/fuse with a similiar binary interface like the tegra ones.

Does it make sense to you?

I haven't looked at the drivers, so I don't know if the tegra interface
is any better or worse than the others. Changing everyone to have the same
interface is definitely a good idea, but of course only if the unified
interface is a good one ;-)

I'm in the process of finding a suitable upstream path for a new eFuse driver
for fuses used on Imagination Technologies SoCs.

This was our last proposal, which follows Tegra's work:

http://www.spinics.net/lists/devicetree/msg59246.html

However, Arnd was reluctant to take yet another efuse driver under
drivers/soc and proposed instead to try to find a unified API. We've
had numerous fuse drivers (tegra, sunxi, imx and img) appearing, so
his concern certainly makes sense.

I've talked to Arnd on IRC and we agreed to create a new directory
drivers/efuse. As a first step we would just move the tegra driver,
and add the new drivers (img on my side, and possibly mxs on
Stefan's).  Perhaps we would also pull the sunxi_sid driver as well.

Having the drivers together would allow us to come up with a unified API
as follow up work.

How does this sound? If you have no objections to this, I can go
ahead and try to prepare some RFCs.

It sounds great :)

Could you put me in Cc whenever you send some patches?

Thanks!
Maxime
