TSENS is part of GCC, hence add TSENS properties as part of GCC node.
Also add thermal zones and qfprom nodes.
Update GCC bindings doc to mention the possibility of optional TSENS
properties that can be part of GCC node.

Did you try to read the content of the qfprom from userspace?

Hi, no I haven't tried it, I can give it a try tomorrow when I
have access to my board and see whats going wrong, but I did
look at Andys for-next and the defconfig still does not have
either nvmem or qcom-qfprom drivers enabled.
Did you manually enable them? or are you seeing this with the drivers
still disabled?

I merged my for-next with the current next and enabled the options. I
reproduced Paolo's problem. It feels like either an access issue,
alignment issue (i tried ioread32 which didnt work). It fails
regardless of the TSENS being enabled.

This was reported in some other forum as well, after some investigation
we concluded that it looks like one of the entries are locked down -
probably from some security reason.
I'm not aware of any way to query this configuration. But the main use
case for the qfprom is in-kernel access to certain elements and that we
do get from the driver as is...

Yeah this appears to be the case. So I guess the response is 'don't
do that'. At least don't cat or od the file. You need to seek and
read.

True, but the dev file is user readable and any user can trigger it (or
any regression test that rummage among dev files looking for bugs).
