Subject: Re: [PATCH v2 1/9] arm64: dts: hi3660: enable idle states
Date: Thu, 10 Aug 2017 12:07:07 +0200 [thread overview]
Message-ID: <b3d8f55b-3d70-9b3a-a4c6-474a933a13a9@linaro.org> (raw)
In-Reply-To: <20170810022615.19204-2-guodong.xu@linaro.org>
Hi Guodong, Leo,
there are several typos in the patch description. I *humbly* propose an
alternate description to make it a bit more English friendly.
"""
There are two clusters on the Hi3660, the first one is Cortex-A53 based
and the other one is Cortex-A73 based. These two clusters have different
idle states.
Thanks to Daniel Lezcano's recent changes, the generic ARM cpuidle
driver can now support several clusters with different idle states, thus
supporting the big.Little architecture.
In addition to the WFI idle state which is the default shallowest state
for all ARM cpus, the Hi3660 supports the following states:
- CA53 CPUs:
- CPU_SLEEP: CPU power off state
- CLUSTER_SLEEP_0: Cluster power off state
- CA73 CPUs:
- CPU_NAP: CPU retention state
- CPU_SLEEP: CPU power off state
- CLUSTER_SLEEP_1: Cluster power off state
This patch adds the idle states description for the Hi3660 to the device
tree.
"""
Other than that.
