Subject[PATCH v3 00/10] arm64: dts: hi3660: add more device nodes
Message-ID<uekk9-2xb-5@gated-at.bofh.it>
This patchset adds more device nodes for hi3660 and hikey960, including:
 - cpu idle states
 - L2 cache
 - PMU
 - OP-TEE
 - reboot
 - pstore
 - DMA
 - watchdog

Patch 7 fixes an issue in mmc nodes, by adding 'reset'
Patch 8 change bluetooth uart max-speed to 3Mbps

HiKey960 is one of 96boards. For details information about it, please
refer to [1].

===
Major changes in v3:
 - update commit message of patch 1, as suggested by Daniel Lezcano
 - add patch 10 for watchdog bindings

Major changes in v2:
 - add patch 8 to change bluetooth uart max-speed to 3Mbps
 - add patch 9 for DMA node.

#1710771 — [PATCH v3 01/10] arm64: dts: hi3660: enable idle states

FromGuodong Xu <guodong.xu@linaro.org>
Date2017-08-14 12:00 +0200
Subject[PATCH v3 01/10] arm64: dts: hi3660: enable idle states
Message-ID<uekka-2xb-13@gated-at.bofh.it>
In reply to#1710770
From: Leo Yan <leo.yan@linaro.org>

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.
