Subject[PATCH v6 7/8] ARM: dts: Introduce HPE GXP Device tree
Date
From: Nick Hawkins <nick.hawkins@hpe.com>

The HPE SoC is new to linux. A basic device tree layout with minimum
required for linux to boot including a timer and watchdog support has
been created.

The dts file is empty at this point but will be updated in subsequent
updates as board specific features are enabled.

Signed-off-by: Nick Hawkins <nick.hawkins@hpe.com>

---
v6:
* Added cache-controller to CPU
* Removed hpe,gxp-wdt and removed simple-mfd from hpe,gxp-timer
* Added space after ',' in compatible lists containing more than one
item
* Switched clock name iopclk to iop based on feedback from
hpe,gxp-timer.yaml
* Added clock labels clock-0 and clock-1
* Added dma-ranges to ahb
* Changed subject to better match ones in the log
* Changed description to fit 75 characters per line
v5:
* Fixed commit message to show previous changes
* Fixed typo ehci -> echi
v4:
* Removed hpe,gxp-cpu-init as it was no longer necessary
* Removed bootargs as requested
* Removed empty ahb node
* Moved reg after compatible, everywhere
* Removed osc and memclk
* Removed syscon@c00000f8 as it was not necessary for boot
* Fixed Alphabetical issue in dts/Makefile
* Added specific board binding for dl360gen10
* Removed empty node
* Added Accurate Clock Architecture
* Fixed generic-echi and generic-ochi issues
* Removed i2cg
v3:
* Fixed issues with warnings
* Used proper patchset format
v2:
* Reduced size of dtsi to essential components
* Followed the proper format for having a dtsi and
dts
