Cixtech P1 (internal name sky1) is high performance generic Armv9 SoC.
Orion O6 is the world's first open source Arm V9 Motherboard built by
Radxa. You could find brief introduction for SoC and related boards at:
https://radxa.com/products/orion/o6#overview

In this series, we add initial SoC and board support for Kernel building.
Patch 1-2: Add dt-binding doc for CIX and its sky1 SoC
Patch 3: add related maintainter entry
Patch 4-5: add Arm64 build support
Patch 6: add initial dts support for SoC and Orion O6 board

To run upstream kernel at Orion O6 board, you need to use BIOS
released by Radxa:
https://docs.radxa.com/en/orion/o6/bios/install-bios

Changes for v2:
- Pass dts build check with below commands:
make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=vendor-prefixes.yaml
make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=arm/cix.yaml
make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb
- Re-order the patch set, and move vendor-perfixes to the 1st patch.
- Patch 4: Ordered Kconfig config entry by alpha-numerically
- Patch 5: Corrects the Ack tag's name
- Patch 6: see below.
1) Corrects the SoF tag's name
2) Fix several coding sytle issues
3) move linux,cma node to dts file
4) delete memory node, memory size is passed by firmware
5) delete uart2 node which will be added in future patches
6) Improve for pmu and cpu node to stands for more specific cpu model
7) Improve the timer node and add hypervisor virtual timer irq
