Please choose whatever is easier for you. I would like to prevent to have more patches floating around. As we are close the to the merge window, I think we can live with the missing stubs ATM. But in the future, provide an immutable branch with the fixes, so we can share it and prevent these issues. -- Daniel

It's not easy to track all dependencies, I keep forgetting when and which patches are already applied. Hopefully nobody bisects code with COMPILE_TEST=y, so this should be a minor issue. Sorry for the inconvenience.
Hi, This series adds support for the thermal sensor that is found on NVIDIA Tegra30 SoC. Sensor monitors temperature and voltage of the SoC, it also emits signals to the power management and clock controllers that are performing the emergency shut down and the CPU frequency throttling when a pre-programmed temperature levels are reached. Changelog: v4: - Removed DIV2 CPU frequency throttling and cooling device part as was suggested by Daniel Lezcano since we need to notify cpufreq about the updated frequency and change the thermal pressure. The thermal pressure change should co-exists with the cpufreq_cooling. This all needs some more thought, so the DIV2 mitigation will come sometime later. - Added ack from Thierry Reding. - Changed default TZ trips in the device-tree to the silicon temperature levels, instead of the average device levels. v3: - No code changes. CC'ed linux-pm, which was previously missed by accident. Not sure how much that is important for the thermal patches, but won't hurt to re-send since only DT binding was reviewed so far. v2: - Made a very minor improvement to one error message, it now prints number of channel at which error occurred. - Added r-b from Rob Herring to the binding.
