From 7561dfbf3b3451957c5d3fc52f53c78e78ed3034 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Wed, 7 Jun 2023 08:59:38 -0700 Subject: xtensa: drop platform_halt and platform_power_off Instead of using xtensa-specific platform_halt and platform_power_off callbacks use do_kernel_power_off in the machine_halt and machine_power_off and reimplement existing platform_halt and platform_power_off users with register_sys_off_handler. Drop platform_halt and platform_power_off declarations and default implementations.
