Hi All,
> The whole idea is

> 2) remove passive specific requirement, aka, tc1/tc2, and

> algorithm. (patch 4,5)
> 3) introduce new function thermal_zone_trip_update(), this contains the
> code for the general cooling algorithm. (patch 6)
> 4) rename some thermal structures. Use thermal_instance instead of

> thermal_zone_device has a list of all the thermal instances in this

I talked to Rui about this patch set and my other patch sets.
Rui suggested me to rebase my patches on top of his changes.
So, I hope Rui will be able to clean up these 12 patches and submit them
(in a week's time :-)
I will rebase my patches on top of them.
Also, Rui promised me that he can host a tree for us to easily pick up changes,
Let us see :-)
Thanks,
Durga
