From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Samuel Holland <samuel@sholland.org>
Date: Sat, 16 Jan 2021 01:58:22 -0600
Subject: [PATCH] allwinner: psci: Improve system shutdown/reset sequence
- When the SCPI shutdown/reset command returns success, the SCPI
implementation is still waiting for the CPU to enter WFI. Do that.
- Peform board-level poweroff before CPU poweroff. If there is a PMIC
available, it will turn everything off including the CPUs, so doing
CPU poweroff first is a waste of cycles.
- During poweroff, attempt to turn off the local CPU using the ARISC.
This should use slightly less power than just an infinite WFI.
- Drop the WFI in the reset failure path. The panic will hang anyway.
