Subject: [PATCH 21/33] ARM: dts: exynos: Add CPU cooling in Universal C210
Date:   Sun, 30 Aug 2020 15:51:48 +0200
Message-Id: <20200830135200.24304-21-krzk@kernel.org>
In-Reply-To: <20200830135200.24304-1-krzk@kernel.org>
References: <20200830135200.24304-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add missing cooling devices for CPU thermal zones in Exynos4210
Universal C310 board.  This allows to scale down CPU frequency (and
voltage) in case of thermal pressure.
