This patchset adds more device nodes for hi3660 and hikey960, including:
- cpu idle states
- L2 cache
- PMU
- OP-TEE
- reboot
- pstore
- DMA
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 v2:
- add patch 8 to change bluetooth uart max-speed to 3Mbps
- add patch 9 for DMA node.

On Hi3660 there have two clusters, one is CA53 cluster and another is
CA73 cluster. This two clusters have different idle states separately.
With Daniel Lezcano's patch (ARM: cpuidle: Support asymmetric idle
definition), now ARM idle driver can support different clusters with
different idle states.
Base on this, this patch is to bind two clusters idle states on Hi3660.
Except the "WFI" states are enabled by default for all CPUs, this patch
also binds below extra idle states:
- CA53 CPUs have two more states:
CPU_SLEEP: CPU power off state
CLUSTER_SLEEP_0: Cluster power off state
- CA73 CPUs have three more states:
CPU_NAP: CPU retention state
CPU_SLEEP: CPU power off state
CLUSTER_SLEEP_1: Cluster power off state

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.

This patch reserves some memory in the DTS and sets up a
pstore device tree node to enable pstore support on HiKey960.
