acpi ec: Fix possible double io port registration

2010-08-03T13:49:13Z

which will result in a harmless but ugly WARN message on some machines. Signed-off-by: Thomas Renninger CC: mjg59@srcf.ucam.org CC: platform-driver-x86@vger.kernel.org CC: linux-acpi@vger.kernel.org CC: astarikovskiy@suse.de CC: akpm@linux-foundation.org Signed-off-by: Matthew Garrett

ACPI: Register EC io ports in /proc/ioports

2010-08-03T13:49:09Z

Formerly these have been exposed through /proc/.. Better register them where all IO ports should get registered and scream loud if someone else claims to use them. EC data and command port typically should show up like this then: ... 0060-0060 : keyboard 0062-0062 : EC data 0064-0064 : keyboard 0066-0066 : EC command 0070-0071 : rtc0 ...

ACPI: Provide /sys/kernel/debug/ec/...

2010-08-03T13:49:08Z

This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.

ACPI: Remove /proc/acpi/embedded_controller/..

2010-08-03T13:49:06Z

Other patches in this series add the same info to /sys/... and /proc/ioports. The info removed should never have been used in an application, eventually someone read it manually. /proc/acpi is deprecated for more than a year anyway...

ACPI / EC: Do not use acpi_set_gpe

2010-07-07T02:34:27Z

The EC driver is the last user of acpi_set_gpe() and since it is guaranteed that the EC GPE will not be shared, acpi_disable_gpe() and acpi_enable_gpe() may be used for disabling the GPE temporarilty if a GPE storm is detected and re-enabling it during EC transactions.

ACPI / EC: Drop suspend and resume routines

2010-07-07T02:34:26Z

The suspend and resume routines provided by the EC driver are not really necessary, because the handler of the GPE disabled by them is not going to be executed after suspend_device_irqs() and before resume_device_irqs() anyway. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

ACPICA: Remove wakeup GPE reference counting which is not used

2010-07-07T02:34:26Z

After the previous patch that introduced acpi_gpe_wakeup() and modified the ACPI suspend and wakeup code to use it, the third argument of acpi_{enable|disable}_gpe() and the GPE wakeup reference counter are not necessary any more. Remove them and modify all of the users of acpi_{enable|disable}_gpe() accordingly. Also drop GPE type constants that aren't used any more. Signed-off-by: Rafael J.
