The existing mechanism for providing IDs explicitly is for compatiblity with implementations prior to PSCI 0.2. We should expect any PSCI 0.2+ compliant implementation to use the mandated IDs unless someone has a compelling reason why they need PSCI 0.2+ but cannot use the mandated IDs.
I would hope that any ACPI system with PSCI has PSCI 0.2+.
Thanks, Mark.
And to be clear, this is the stance we have taken with ACPI. Ie we are not allowing function overrides. The only knowledge of PSCI in ACPI will basically be to say whether PSCI is present, and the conduit HVC/SMC
Okay. I will re-spin the patch with this feedback and possibly split it to address current DT code and ACPI code separately.
