According to the Microsoft documentation for Windows 8 convertible devices, these devices should implement a PNP0C60 "laptop/slate mode state indicator" ACPI device. This device can work in 2 ways, if there is a GPIO which directly indicates the device is in tablet-mode or not then the direct-gpio mode should be used. If there is no such GPIO, but instead the events are coming from e.g. the embedded-controller, then there should still be a PNP0C60 ACPI device and event-injection should be used to send the events. The drivers/platform/x86/intel-vbtn.c code is an example from a standardized manner of doing the latter. On various 2-in-1s with either a detachable keyboard, or with 360° hinges, the direct GPIO mode is indicated by an ACPI device with a HID of INT33D3, which contains a single GpioInt in its ACPI resource table, which directly indicates if the device is in tablet-mode or not. This commit adds support for this to the soc_button_array code, as well as for the alternative ID9001 HID which some devices use instead of the INT33D3 HID. Signed-off-by:

This is a preparation patch for adding support for Intel INT33D3 ACPI devices. These INT33D3 devices follow yet another Intel defined (but not documented) ACPI GPIO button standard. Unlike the ACPI GPIO button devices supported so far, the GPIO used in the INT33D3 devices is active-high, rather then active-low. This commit makes setting the gpio_keys_button.active_low flag configurable through the soc_button_info struct and enables it for all currently supported devices. Signed-off-by:

Commit 696c6523 ("platform/x86: thinkpad_acpi: add mapping for new hotkeys") added support for a bunch of new hotkeys, but the clipping/snipping tool hotkey got ignored because there was no good key-code to map it to. Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit 3b059da9 ("Input: allocate keycode for "Selective Screenshot" key") quoting from the commit message: "New Chrome OS keyboards have a "snip" key that is basically a selective screenshot (allows a user to select an area of screen to be copied). Allocate a keycode for it." Support for this "snip" key seems like it is also a good match for the clipping/snipping tool hotkey, so map this hotkey to the new KEY_SELECTIVE_SCREENSHOT key-code.

New Lenovo Thinkpad models, e.g. the X1 Carbon 8th gen and the new T14 gen1 models have 3 new symbols / shortcuts on their F9-F11 keys (and the thinkpad_acpi driver receives 3 new hkey events for these): F9: Has a symbol resembling a rectangular speech balloon, the manual says the hotkey functions shows or hides the notification center F10: Has a symbol of a telephone horn which has been picked up from the receiver, the manual says: "Answer incoming calls" F11: Has a symbol of a telephone horn which is resting on the receiver, the manual says: "Decline incoming calls" And these Thinkpad models also send a new 0x1316 hkey events when the Fn + right Shift key-combo is pressed. This commit adds support for these 4 new hkey events. Acked-by: -

The last 2 generations of Lenovo Thinkpads send an acpi_thinkpad event when Fn + right shift is pressed. This is intended for use with "Lenovo Quick Clean" software, which disables the touchpad + kbd for 2 minutes on this key-combo so that healthcare workes can disinfect it. But there is no silkscreen print on the right-keyboard to indicate this, so add a KEY_FN_RIGHT_SHIFT keycode define to use for this key-combo. Signed-off-by:

New Lenovo Thinkpad models, e.g. the X1 Carbon 8th gen and the new T14 gen1 models have 3 new symbols / shortcuts on their F9-F11 keys (and the thinkpad_acpi driver receives 3 new "scancodes" for these): F9: Has a symbol resembling a rectangular speech balloon, the manual says the hotkey functions shows or hides the notification center F10: Has a symbol of a telephone horn which has been picked up from the receiver, the manual says: "Answer incoming calls" F11: Has a symbol of a telephone horn which is resting on the receiver, the manual says: "Decline incoming calls" We have no existing keycodes which are a good match for these, so add 3 new keycodes for these. I noticed that we have a hole in our keycodes between 0x1ba and 0x1c0 which does not seem to be reserved for any specific purpose, so these new 3 codes use 0x1bc - 0x1be, instead of starting at 0x27b.

Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected. Reviewed-by:

Currently the assignment of -ENOMEM to error is redundant because error is not being read and -ENOMEM is being hard coded as an error return. Fix this by returning the error code in variable 'error'; this also allows the error code from a failed call to input_register_device to be preserved and returned to the caller rather than just returning a possibly inappropriate -ENOMEM. Kudos to Dan Carpenter for the suggestion of an improved fix.

The workaround of reading all messages until an invalid is received is a way of forcing the CHG line high, which means that when using edge-triggered interrupts the interrupt can be acquired. With level-triggered interrupts the workaround is unnecessary. Also, most recent maXTouch chips have a feature called RETRIGEN which, when enabled, reasserts the interrupt line every cycle if there are messages waiting. This also makes the workaround unnecessary. Note: the RETRIGEN feature is only in some firmware versions/chips, it's not valid simply to enable the bit. Signed-off-by:

Newer controllers (identified as "pattern" version 2) send higher resolution reports, with 16-bit X and Y coordinates (previous generations used 12-bit values). These new high resolution reports use report ID of 0x60. SMbus controllers use the same buffer size for both the new and old reports, and because of that high resolution reports no longer carry area of contact data with SMbus. Signed-off-by:

On older controllers IC type is reported in the 2nd byte of ETP_I2C_OSM_VERSION_CMD, however if controller's firmware is not flashed correctly it may return incorrect data. Fortunately there is also ETP_I2C_IAP_VERSION_P0_CMD command that can be used when controller in either normal or IAP mode, and which is guaranteed to return accurate data, so let's use it.
