Subject: [PATCH v2 2/5] thermal: cpufreq_cooling: Use new thermal pressure update function
Date:   Fri, 15 Oct 2021 15:45:47 +0100
Message-Id: <20211015144550.23719-3-lukasz.luba@arm.com>
In-Reply-To: <20211015144550.23719-1-lukasz.luba@arm.com>
References: <20211015144550.23719-1-lukasz.luba@arm.com>
Precedence: bulk

Thermal pressure provides a new API, which allows to use CPU frequency
as an argument. That removes the need of local conversion to capacity.
Use this new function and remove old conversion code.
