Hi,
This series adds support for for using CPUFreq as a cooling device for
the A57 CUP:s on Renesas H3 and M3-W SoC:s. It depends on Simon Horman's
topic/rcar-gen3-cpufreq branch [1] and is tested on-top the latest
renesas-drivers on H3 and M3-W. For test results and test procedure
please see:
http://elinux.org/R-Car/Tests:rcar_gen3_thermal
Few notes on the specific values used in this series and why they might
need to be changed.
- The trip point temperature of 95000 used is the most conservative one
from the BSP and maybe should be set at 110000 which is the most
aggressive one in the BSP.
- The cooling states described in all cooling-maps nodes might be
subject to change depending on the out-come of the ongoing review
process of Simon's work. It should use the highest possible cooling
state so if the number of states change due review of his work this
should be reflected in this series.
