#1590247 — [PATCH 0/7] thermal: ti-soc-thermal: Migrate slope/offset data to device tree

Currently the slope and offset values for calculating the
hot spot temperature of a particular thermal zone is part
of driver data. Pass them here instead and obtain the values
while of node parsing.

Tested for the slope and constant values on DRA7-EVM.

Are the dts changes safe for me to pick separately into
omap-for-v4.12/dt?

Regards,

Tony

OK cool. It might be worth checking how it was configured with
the legacy platform data.

Tony,

Seems like omap3 has no thermal_zone node defined in Device Tree.
It seems like it still uses driver data. I would need to add that as 
well. Can you confirm that? If yes i will send a new series with the 
omap3 device tree changes as well.

Thanks,
Keerthy
