SC9860 is a Spreadtrum SoC with eight Cortex A53, which are divided
into 4 Big cores and 4 little cores.

This patch-set provides a basic configuration for SC9860 in device tree
to make it run to console.  After this we will continue to submit other
device drivers step by step, which are using on most of Spreadtrum's SoCs.

Changes from v4:
* Addressed Rob's comments
  use serial@0 instead of serial@000000;
* Added Rob's Acked-by on patch 2/4 and 3/4.

Changes from v3:
* Rebased v4.11-rc2;
* Added Reviewed-by of Mathieu;
* Addressed Rob's comments:
  - Documented sprd serial competible according to Rob's suggestion
  - Revised serial node name to match its offset;
* Added STM device node in dt.

Changes from v2:
* Addressed comments from Mathieu:
  - Removed CoreSight devices' lables from DT;
  - Added another level of imbrication for ETFs which have more than one port;
* Addressed comments from Rob:
  - Switched to use SPDX-License-Identifier tag instead;
  - Moved the 26m fixed clock node to top level in DT;
  - Splited the patch into two, since they were revising two dt-bindings;
  - Removed redundant space from sprd-usrt.txt;
  - Removed useless property from the sprd_uart example of DT configuration.

Changes from v1:
* Removed useless idle-state node 'deep_sleep' from DT
* Removed useless property 'sc-id' from DT
* Removed 'clock-frequency' property from the node 'timer'
* Added another compatible string '"arm,cortex-a53-pmu"' and property
  'interrupt-affinity' for pmu
* Kept using the existed compatible string of sprd_serial driver, and added
  a new one for sc9860 in DT.

Thanks,
Chunyan

From: Orson Zhai <orson.zhai@spreadtrum.com>

SC9860G is a 8 cores of A53 SoC with 4G LTE support SoC from Spreadtrum.

According to regular hierarchy of sprd dts, whale2.dtsi contains SoC
peripherals IP nodes, sc9860.dtsi contains stuff related to ARM core stuff
and sp9860g dts is for the board level.

From: Orson Zhai <orson.zhai@spreadtrum.com>

SC9860G is a 8 cores of A53 SoC with 4G LTE support SoC from Spreadtrum.

According to regular hierarchy of sprd dts, whale2.dtsi contains SoC
peripherals IP nodes, sc9860.dtsi contains stuff related to ARM core stuff
and sp9860g dts is for the board level.

* [PATCH V5 1/4] arm64: dts: Add basic DT to support Spreadtrum's SP9860G
@ 2017-03-27  6:06   ` Chunyan Zhang

From: Chunyan Zhang @ 2017-03-27  6:06 UTC (permalink / raw)
  To: linux-arm-kernel

From: Orson Zhai <orson.zhai@spreadtrum.com>

SC9860G is a 8 cores of A53 SoC with 4G LTE support SoC from Spreadtrum.

According to regular hierarchy of sprd dts, whale2.dtsi contains SoC
peripherals IP nodes, sc9860.dtsi contains stuff related to ARM core stuff
and sp9860g dts is for the board level.

SC9860 use the same serial device which SC9836 uses, so added a new
compatible string to support SC9860 as well, also added an example
of how to describe this serial device in DT.

From: Wei Qiao <wei.qiao@spreadtrum.com>

SPRD_TIMEOUT was 256, which is too small to wait until the status
switched to workable in a while loop, so that the earlycon could
not work correctly.
