[PATCH v5 0/3] thermal: mediatek: Add cpu dynamic power cooling model.
From: Dawei Chien
Date: Tue Dec 15 2015 - 22:59:45 EST
Use Intelligent Power Allocation (IPA) technical to add dynamic power model
for binding CPU thermal zone. The power allocator governor allocates power
budget to control CPU temperature.
Power Allocator governor is able to keep SOC temperature within a defined
temperature range to avoid SOC overheat and keep it's performance.
mt8173-cpufreq.c need to register its' own power model with power allocator
thermal governor, so that power allocator governor can allocates suitable
power budget to control CPU temperature.

Change since V4:
1. Remove unnecessary error-checking for mt8173-cpufreq.c
2. Initializing variable capacitance with 0
Change since V3:
1. Remove static power model
2. Split V3's device tree in two for thermal zones and dynamic power models respectively
Change since V2:
1. Move dynamic/static power model in device tree
Change since V1:
1. Include mt8171.h and sort header file for mt8173.dtsi
