Hi Dmitry, Maxime, et al.

Here is a patch-set for the sun4i-ts driver temperature sensor support, it consists of 2 fixes:

1) Use a better temperature curve for A10 SoCs to avoid reporting a way to high temperature.

Quoted 6 lines
Quoted 3 lines

2) Start with reporting an "estimated" temperature of 40 degrees rather then returning -EAGAIN until we get the first temperature ready interrupt to avoid the kernel tempzone core logging errors because of our -EAGAIN return.

No, I think we better teach thermal core not to complain about -EAGAINs.

I was wondering if that would not be a better fix myself, so ack. I'll go do a patch for that and submit it to the thermalzone maintainer.

Regards,

Hans
