Subject[PATCH v5 0/6] Initialise thermal framework and cpufreq earlier during boot
Date
Changes since v4:
- Collect Acks
- Pick the US spelling for 'initialis^Hze' consistently.

Changes since v3:
- Init schedutil governor earlier too
- Simplified changes to thermal_init() error path
- Collects Acks

Changes since v2:
- Missed one patch when posting v2. Respinning.

Changes since v1:
- Completely get rid of netlink support in the thermal framework.
- This changes the early init patch to a single line - change to
core_initcall. Changed authorship of patch since it is nothing like the
original. Lina, let me know if you feel otherwise.
- I've tested to make sure that the qcom-cpufreq-hw driver continues to
work correctly as a module so this won't impact Android's GKI plans.
- Collected Acks

Device boot needs to be as fast as possible while keeping under the thermal
envelope. Now that thermal framework is built-in to the kernel, we can
initialize it earlier to enable thermal mitigation during boot.

We also need the cpufreq HW drivers to be initialised earlier to act as the
cooling devices. This series only converts over the qcom-hw driver to
initialize earlier but can be extended to other platforms as well.

Amit Kucheria (6):
thermal: Remove netlink support
thermal: Initialize thermal subsystem earlier
cpufreq: Initialize the governors in core_initcall
cpufreq: Initialize cpufreq-dt driver earlier
clk: qcom: Initialize clock drivers earlier
cpufreq: qcom-hw: Move driver initialization earlier
