Subject: [PATCH v2 1/3] arm64: dts: amlogic: a1: add cooling-cells for DVFS feature
Date: Thu, 28 Mar 2024 22:26:35 +0300 [thread overview]
Message-ID: <20240328192645.20914-2-ddrokosov@salutedevices.com> (raw)
In-Reply-To: <20240328192645.20914-1-ddrokosov@salutedevices.com>
It's used for CPU with DVFS feature to specify minimum and maximum
cooling state used in the reference.
Without these values DVFS will not work and dtbs_check will raise the
error.
