While looking for other ARMv8 based platform, I found that the RK3368
platform has the same SCPI implementation as Amlogic.

They extended it with DDR, system and thermal commands.

Look at :

https://github.com/geekboxzone/mmallow_kernel/blob/geekbox/drivers/mailbox/scpi_protocol.c



So the SCPI must have a framework to allow different protocol
versions, and must allow command extension. Grouping Rockchip and
Amlogic should be done, thus needing a generic name like vendor_scpi
or with a version.


Makes sense. I understand the need to reuse and I need a bit of time to
have a look at the code(both Amlogic one's you have pointed out and the
Rockchip one) in detail to see what's the best way to proceed. I will
have a look at this later this week and get back to you.

Sudeep, could you somehow find out which version of the protocol
AmLogic and Rockchip based their SCPI development ?


Yes I tried checking with Rockchip but didn't get a response. But my
guess is that it was some preliminary unpublished version of SCPI
unfortunately :(
