From 1253f7aabfebc51446dbec5c8895c5c8846dfe06 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Thu, 28 Aug 2008 10:06:16 +0800 Subject: dock: introduce .uevent for devices in dock, eg libata dock's uevent reported itself, not ata. It might be difficult to find an ata device just according to a dock. This patch introduces docking ops for each device in a dock. when docking, dock driver can send device specific uevent. This should help dock station too (not just bay) Signed-off-by: Shaohua Li Acked-by: Tejun Heo Signed-off-by: Len Brown --- include/acpi/acpi_drivers.h | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'include/acpi') diff --git a/include/acpi/acpi_drivers.h b/include/acpi/acpi_drivers.h index e5f38e5ce86f..4f5042a0ef80 100644 --- a/include/acpi/acpi_drivers.h +++ b/include/acpi/acpi_drivers.h @@ -115,12 +115,17 @@ int acpi_processor_set_thermal_limit(acpi_handle handle, int type); /*-------------------------------------------------------------------------- Dock Station -------------------------------------------------------------------------- */ +struct acpi_dock_ops { + acpi_notify_handler handler; + acpi_notify_handler uevent; +}; + #if defined(CONFIG_ACPI_DOCK) || defined(CONFIG_ACPI_DOCK_MODULE) extern int is_dock_device(acpi_handle handle); extern int register_dock_notifier(struct notifier_block *nb); extern void unregister_dock_notifier(struct notifier_block *nb); extern int register_hotplug_dock_device(acpi_handle handle, - acpi_notify_handler handler, + struct acpi_dock_ops *ops, void *context); extern void unregister_hotplug_dock_device(acpi_handle handle); #else @@ -136,7 +141,7 @@ static inline void unregister_dock_notifier(struct notifier_block *nb) { } static inline int register_hotplug_dock_device(acpi_handle handle, - acpi_notify_handler handler, + struct acpi_dock_ops *ops, void *context) { return -ENODEV; -- cgit v1.2.3
