2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva1-4/+4
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2019-07-28platform/x86: surfacepro3_button: Fix device checkMaximilian Luz1-0/+47
Do not use the surfacepro3_button driver on newer Microsoft Surface models, only use it on the Surface Pro 3 and 4. Newer models (5th, 6th and possibly future generations) use the same device as the Surface Pro 4 to represent their volume and power buttons (MSHW0040), but their actual implementation is significantly different. This patch ensures that the surfacepro3_button driver is only used on the Pro 3 and 4 models, allowing a different driver to bind on other models.

2018-01-11platform/x86: surfacepro3: Support for wakeup from suspend-to-idleRafael J. Wysocki1-1/+3
Modify surface_button_notify() to make it wake up the system from suspend-to-idle (by reporting "hard" wakeup events while suspended) and add wakeup initialization to surface_button_add() for wakeup events reported by this driver to work at all.

2016-05-27surfacepro3_button: Add a warning when switching to tablet modeAndy Shevchenko1-2/+7
Microsoft Surface Book has a tablet mode button. Print another message once on this event instead of repeating "Unknown event...". Unfortunately, proper support involves the _DSM method, which is not a discoverable interface. Just print a warning for now.

2016-01-19surface pro 4: Add support for Surface Pro 4 ButtonsWeng Xuetian1-4/+6
Surface Pro 4 buttons are managed by a device with _HID "MSHW0040" different from Surface Pro 3. This commit adds MSHW0040 to id list to support the Surface Pro 4.

2015-08-26surface pro 3: Add support driver for Surface Pro 3 buttonsChen Yu1-0/+216
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design Guide for SoC Platform", code in drivers/input/misc/soc_array.c can not detect these buttons on it. According to bios implementation, Surface Pro 3 encapsulates these buttons in a device named "VGBI", with _HID "MSHW0028". When any of the buttons is pressed, a specify ACPI notification code for this button will be delivered to "VGBI". For example, if power button is pressed down, ACPI notification code of 0xc6 will be sent by Notify(VGBI, 0xc6). This patch leverages "VGBI" to distinguish different ACPI notification code from Power button, Home button, Volume button, then dispatches these code to input layer. Lid is already covered by acpi button driver, so there's no need to rewrite.
