Hi Amit, vaguely related question, since you are working on SDM845 thermal stuff: Do you have plans to add CPU cooling devices? I raised the point during the review of the CPUfreq HW, however there was no clear answer: https://lore.kernel.org/patchwork/patch/966833/#1164748 The driver is still under development/review, but I wonder what the path forward is.
