ACPI: button: trigger wakeup key events

2023-12-29T17:47:49Z

Andorid can wakeup from various wakeup sources, but only several wakeup sources can wake up screen with right events(POWER, WAKEUP) from input device. Regarding pressing acpi power button, it can resume system and ACPI_BITMASK_WAKE_STATUS and ACPI_BITMASK_POWER_BUTTON_STATUS are set in pm1a_sts, but kernel does not report any key event to user space during resuming by default. So, send wakeup key event to user space during resume from power button. Signed-off-by: Ken Xue Reviewed-by: Andy Shevchenko [ rjw: Subject edits ] Signed-off-by: Rafael J. Wysocki

Merge branches 'acpi-thermal' and 'acpi-button'

Merge ACPI thermal driver cleanups and ACPI button drivers rework for 6.5-rc1: - Clean up the ACPI thermal driver and drop some dead or otherwise unneded code from it (Rafael Wysocki). - Rework the handling of notifications in the ACPI button drivers so as to allow the common notification handling code for devices to be simplified (Rafael Wysocki). * acpi-thermal: ACPI: thermal: Drop struct acpi_thermal_flags ACPI: thermal: Drop struct acpi_thermal_state ACPI: thermal: Eliminate struct acpi_thermal_state_flags ACPI: thermal: Move acpi_thermal_driver definition ACPI: thermal: Move symbol definitions to one place ACPI: thermal: Drop redundant ACPI_TRIPS_REFRESH_DEVICES symbol ACPI: thermal: Use BIT() macro for defining flags * acpi-button: ACPI: bus: Simplify installation and removal of notify callback ACPI: tiny-power-button: Eliminate the driver notify callback ACPI: button: Use different notify handlers for lid and buttons ACPI: button: Eliminate the driver notify callback

ACPI: button: Use different notify handlers for lid and buttons

2023-06-16T17:48:08Z

Since the lid handling in acpi_button_notify() is special, introduce acpi_lid_notify() specifically for handling lid notifications. Signed-off-by: Rafael J. Wysocki

ACPI: button: Eliminate the driver notify callback

2023-06-16T17:48:08Z

Rework the ACPI button driver to install notify handlers or fixed event handlers for the devices it binds to by itself, reduce the indentation level in its notify handler routine and drop its notify callback. This will allow acpi_device_install_notify_handler() and acpi_device_remove_notify_handler() to be simplified going forward and it will allow the driver to use different notify handlers for the lid and for the power and sleep buttons.

ACPI: button: Add lid disable DMI quirk for Nextbook Ares 8A

2023-05-17T18:26:43Z

The LID0 device on the Nextbook Ares 8A tablet always reports lid closed causing userspace to suspend the device as soon as booting is complete. Add a DMI quirk to disable the broken lid functionality. Signed-off-by: Hans de Goede Signed-off-by: Rafael J. Wysocki

ACPI: make remove callback of ACPI driver void

2022-11-23T18:11:22Z

For bus-based driver, device removal is implemented as: 1 device_remove()-> 2 bus->remove()-> 3 driver->remove() Driver core needs no inform from callee(bus driver) about the result of remove callback. In that case, commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned. Now we have the situation that both 1 & 2 of calling chain are void-returned, so it does not make much sense for 3(driver->remove) to return non-void to its caller. So the basic idea behind this change is making remove() callback of any bus-based driver to be void-returned. This change, for itself, is for device drivers based on acpi-bus.

ACPI: button: Add DMI quirk for Lenovo Yoga 9 (14INTL5)

2021-08-25T17:57:01Z

The Lenovo Yoga 9 (14INTL5)'s ACPI _LID is bugged: After hibernation the lid is initially reported as closed. Once closing and then reopening the lid reports the lid as open again. This leads to the conclusion that the initial notification of the lid is missing but subsequent notifications are correct. In order fo the Linux LID code to handle this device properly the lid_init_state must be set to ACPI_BUTTON_LID_INIT_OPEN. Signed-off-by: Ulrich Huber Signed-off-by: Rafael J. Wysocki

ACPI: button: Clean up printing messages

2021-02-04T18:45:46Z

Replace the ACPI_DEBUG_PRINT() instance in button.c with an acpi_handle_debug() call, drop the _COMPONENT and ACPI_MODULE_NAME() definitions that are not used any more, drop the no longer needed ACPI_BUTTON_COMPONENT definition from the headers and update the documentation accordingly. While at it, replace the direct printk() invocations with pr_info() (that changes the excessive log level for some of them too) and drop the unneeded PREFIX sybmbol definition from battery.c.

ACPI: button: Add DMI quirk for Medion Akoya E2228T

2020-11-09T18:29:41Z

The Medion Akoya E2228T's ACPI _LID implementation is quite broken, it has the same issues as the one from the Medion Akoya E2215T: 1. For notifications it uses an ActiveLow Edge GpioInt, rather then an ActiveBoth one, meaning that the device is only notified when the lid is closed, not when it is opened. 2. Matching with this its _LID method simply always returns 0 (closed) In order for the Linux LID code to work properly with this implementation, the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN, add a DMI quirk for this. While working on this I also found out that the MD60### part of the model number differs per country/batch while all of the E2215T and E2228T models have this issue, so also remove the " MD60198" part from the E2215T quirk.
