Subject: [PATCH] arm64: dts: qcom: sdm850-lenovo-yoga-c630: lower PSCI cluster idle
Date: Tue, 28 Apr 2026 22:36:49 +0300	[thread overview]
Message-ID: <20260428-c630-fix-idle-v1-1-29d0da326eb3@oss.qualcomm.com> (raw)

With the default PSCI suspend value for cluster idle state Lenovo Yoga
C630 isn't stable enough. For example it might reset if display device
isn't probed early enough. Drop one of the bits from the PSCI suspend
value to make C630 work in stable way.

Fixes: a1ade6cac5a2 ("arm64: dts: qcom: sdm845: Switch PSCI cpu idle states from PC to OSI")
