Hi Peter,

I'm really happy to see the linux mainline upstream work sent. And I have
also reveived radxa orion o6 before the Chinese new year. I have heard
that CIX is testing vendor kernel with ACPI. And now the mainline upstream
work is based on devicetree. I want to know what the upstream work of CIX
would go in the future, are we going to toggle to ACPI instead of
devicetree?

And it would be good to let outsiders know the plan/roadmap of upstream.
For example collaboara is doing good job on upstreaming rockchip[1][2] and
mediatek[3] socs.

Hi Jianfeng,

Thanks for your interesting of our hardware. Radxa will open our
v6.1 device tree vendor kernel source code at the beginning of next month.
For ACPI vendor kernel source code based on v6.6, it has planned to open
at Q2 of this year.

For upstream, we will submit support based on device tree first, since
some common code changes are needed for supporting ACPI well at Arm,
it may involve lots of discussion. After most of IP drivers are
supported by upstream kernel, we will start ACPI upstream work.

For upstream status record for CIX SoC, we will find some public place
for it.
