Subject: [cip-dev] [PATCH RESEND 4.4.y-cip 13/15] cpufreq-dt: Supply power coefficient when registering cooling devices
Date: Thu,  4 Jun 2020 12:17:43 +0800

From: Punit Agrawal <punit.agrawal@arm.com>

commit f8fa8ae06b8c2c25d81c99766f9226adc5c3e073 upstream.

Support registering cooling devices with dynamic power coefficient
where provided by the device tree. This allows OF registered cooling
devices driver to be used with the power_allocator thermal governor.
