From 7d77b247088fb360aa74bfdd9e19bce1e1987668 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Sep 2007 13:14:13 +0900 Subject: libata-pmp-prep: implement sata_async_notification() AN serves multiple purposes. For ATAPI, it's used for media change notification. For PMP, for downstream PHY status change notification. Implement sata_async_notification() which demultiplexes AN. To avoid unnecessary port events, ATAPI AN is not enabled if PMP is attached but SNTF is not available.
