does A311D supports SCPI?

does A311D supports SCPI?

[张 宁]

Hi,

when I'm building minimal kernel config for A311D[1], and find A311D doesn't support SCPI.

and I tried to find answer in A311D datasheet, but no answer.

is SCPI mandatory for Aarch64?

if yes, what's the status of SCPI in A311D?

BTW, what about cpu idle, any progress[2]?

I'm not sure exactly, but it seems it's supported but only for cpu idle.
But for now it's not enabled for mainline kernel.

No

It's something to enable

if SCPI gets enabled then enhanced cpu idle could be enabled.
