Subject: [PATCH 3/3] arm64: dts: update the cpu idle node
Date: Thu, 8 Feb 2018 15:54:36 +0800 [thread overview]
Message-ID: <20180208075436.38443-3-ran.wang_1@nxp.com> (raw)
In-Reply-To: <20180208075436.38443-1-ran.wang_1@nxp.com>
From: Yuantian Tang <andy.tang@nxp.com>
According to PSCI standard v0.2, for CPU_SUSPEND call, which is
used by cpu idle framework, bit[16] of state parameter must be 0.
So update bit[16] of property 'arm,psci-suspend-param', which is
used as state parameter, to 0.
