Subject: [PATCH RFT RFC 3/3] arm64: dts: qcom: sc8280xp: Fix up idle state periods
Date: Mon, 19 Jun 2023 18:18:55 +0200 [thread overview]
Message-ID: <20230619-topic-sc8280xp-idle-v1-3-35a8b98451d0@linaro.org> (raw)
In-Reply-To: <20230619-topic-sc8280xp-idle-v1-0-35a8b98451d0@linaro.org>
Some of the values were wrong, which may have painted a wrong picture
to the scheduler. Fix it.
Fixes: 152d1faf1e2f ("arm64: dts: qcom: add SC8280XP platform")
