From fefe5ab3d67b0ade6200fec5ed6f2812cbcbb658 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 5 Nov 2008 16:17:58 -0700 Subject: ACPI: remove CONFIG_ACPI_POWER Remove CONFIG_ACPI_POWER. It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". The interfaces under CONFIG_ACPI_POWER (acpi_device_sleep_wake(), acpi_power_transition(), etc) are called unconditionally from the ACPI core, so we already depend on it always being present.

It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". Per section 6.5.4 of the ACPI 3.0b specification, OSPM must make Embedded Controller operation regions, accessed via the Embedded Controllers described in ECDT, available before executing any control method. The ECDT table is optional, but if it is present, the above text means that the EC it describes is a required part of the ACPI subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.
