Subject: Thermal: Add platform level information to thermal.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ef87394791206019e4e4e04cb746865f2dc115ed;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Thermal: Add platform level information to thermal.h

This patch adds platform level information to thermal.h
by introducing two structures to hold:
 * bind parameters for a thermal zone,
 * zone level platform parameters
