Subject: [PATCH RFT v2 1/3] arm64: dts: qcom: sc8280xp: Add lower cluster idle states
Date: Wed, 20 Dec 2023 23:12:54 +0100 [thread overview]
Message-ID: <20230619-topic-sc8280xp-idle-v2-1-cde50bf02f3c@linaro.org> (raw)
In-Reply-To: <20230619-topic-sc8280xp-idle-v2-0-cde50bf02f3c@linaro.org>
Apart from a total LLCC + APSS power collapse, SC8280XP can also put
either the DSU rail (CPU + L3), or VDD_CX in power collapse.
Add support for these lower idle states to allow more flexibility.
