Not that I am aware, but I could be totally wrong. The reason I am adding this here for 32-bit ARM is because the ACPI spec mentioned this.
If you think this is not necessary until we introduce ACPI for ARM32, it can be removed.
I think it should be removed (as long as ACPI cannot be selected on arm32).
I agree.
Now there is no plan for ARM32 ACPI as I know, ACPI for ARM targets for ARM64 based enterprise system at now.
While we're at it, do we *really* need to support CONFIG_ACPI_PROCFS_POWER on arm64? It's a deprecated /proc/acpi interface and it would be nice to avoid introducing deprecated behaviour if we can avoid it.
I agree. It is used for laptop ac adapter and battery, I will look into that and clean it up for ARM64.
Thanks Hanjun
