Subject: [PATCH v4 1/6] arm64: dts: rockchip: add thermal zones information on RK3588
Date: Mon, 06 May 2024 13:36:32 +0400 [thread overview]
Message-ID: <20240506-rk-dts-additions-v4-1-271023ddfd40@gmail.com> (raw)
In-Reply-To: <20240506-rk-dts-additions-v4-0-271023ddfd40@gmail.com>
This includes the necessary device tree data to allow thermal
monitoring on RK3588(s) using the on-chip TSADC device, along with
trip points for automatic thermal management.
Each of the CPU clusters (one for the little cores and two for
the big cores) get a passive cooling trip point at 85C, which
will trigger DVFS throttling of the respective cluster upon
reaching a high temperature condition.
All zones also have a critical trip point at 115C, which will
trigger a reset.
