[PATCH v2 0/5] Initialise thermal framework and cpufreq earlier during boot

From: Amit Kucheria
Date: Thu Oct 17 2019 - 06:31:02 EST


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 (5):
thermal: Initialize thermal subsystem earlier
cpufreq: Initialise the governors in core_initcall
cpufreq: Initialize cpufreq-dt driver earlier
clk: qcom: Initialise clock drivers earlier
cpufreq: qcom-hw: Move driver initialisation earlier
