Subject: [PATCH 20/33] ARM: dts: exynos: Add CPU cooling in SMDKv310
Date: Sun, 30 Aug 2020 15:51:47 +0200	[thread overview]
Message-ID: <20200830135200.24304-20-krzk@kernel.org> (raw)
In-Reply-To: <20200830135200.24304-1-krzk@kernel.org>

Add missing cooling devices for CPU thermal zones in Exynos4210 SMDKv310
board.  This allows to scale down CPU frequency (and voltage) in case of
thermal pressure.
