When TOUCHSCREEN_ADC is enabled and IIO_BUFFER is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for IIO_BUFFER_CB Depends on [n]: IIO [=y] && IIO_BUFFER [=n] Selected by [y]: - TOUCHSCREEN_ADC [=y] && !UML && INPUT [=y] && INPUT_TOUCHSCREEN [=y] && IIO [=y] The reason is that TOUCHSCREEN_ADC selects IIO_BUFFER_CB without depending on or selecting IIO_BUFFER while IIO_BUFFER_CB depends on IIO_BUFFER. This can also fail building the kernel. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.

The i8042 module exports several symbols which may be used by other modules. Before this commit it would refuse to load (when built as a module itself) on systems without an i8042 controller. This is a problem specifically for the asus-nb-wmi module. Many Asus laptops support the Asus WMI interface. Some of them have an i8042 controller and need to use i8042_install_filter() to filter some kbd events. Other models do not have an i8042 controller (e.g. they use an USB attached kbd). Before this commit the asus-nb-wmi driver could not be loaded on Asus models without an i8042 controller, when the i8042 code was built as a module (as Arch Linux does) because the module_init function of the i8042 module would fail with -ENODEV and thus the i8042_install_filter symbol could not be loaded. This commit fixes this by exiting from module_init with a return code of 0 if no controller is found. It also adds a i8042_present bool to make the module_exit function a no-op in this case and also adds a check for i8042_present to the exported i8042_command function. The latter i8042_present check should not really be necessary because when builtin that function can already be used on systems without an i8042 controller, but better safe then sorry.

All evdev clients share a common waitgroup. On new input events, all clients waiting on this waitgroup are woken up, even those filtering out the events, possibly more than once per event. This leads to duplicated and unwanted wakeups. Split the shared waitgroup into per-client waitgroups for more fine-grained wakeups. Signed-off-by:

Add support for the bt541 touchscreen IC from zinitix, loosely based on downstream driver. The driver currently supports multitouch (5 touch points). The bt541 seems to support touch keys, but the support was not added because that functionality is not being utilized by the touchscreen used for testing. Based on the similartities between downstream drivers, it seems likely that other similar touchscreen ICs can be supported with this driver in the future. Signed-off-by:

On an AMD chromebook, where the same I2C bus is shared by both Raydium touchscreen and a trackpad device, it is observed that interleaving of I2C messages when `raydium_i2c_read_message()` is called leads to the Raydium touch IC reporting incorrect information. This is the sequence that was observed to result in the above issue: * I2C write to Raydium device for RM_CMD_BANK_SWITCH * I2C write to trackpad device * I2C read from trackpad device * I2C write to Raydium device for setting address * I2C read from Raydium device >>>> This provides incorrect information This change adds a new helper function `raydium_i2c_xfer()` that performs I2C transactions to the Raydium device. It uses the register address to decide if RM_CMD_BANK_SWITCH header needs to be sent to the device (i.e. if register address is greater than 255, then bank switch header is sent before the rest of the transaction). Additionally, it ensures that all the I2C operations performed as part of `raydium_i2c_xfer()` are done as a single i2c_transfer. This guarantees that no other transactions are initiated to any other device on the same bus in between. Additionally, `raydium_i2c_{send|read}*` functions are refactored to use this new helper function. Verified with the patch across multiple reboots (>100) that the information reported by the Raydium touchscreen device during probe is correct.

Some 2-in-1s which use the soc_button_array driver have this ugly issue in their DSDT where the _LID method modifies the irq-type settings of the GPIOs used for the power and home buttons. The intend of this AML code is to disable these buttons when the lid is closed. The AML does this by directly poking the GPIO controllers registers. This is problematic because when re-enabling the irq, which happens whenever _LID gets called with the lid open (e.g. on boot and on resume), it sets the irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs the type to, and expects it to be, IRQ_TYPE_EDGE_BOTH. This commit adds a workaround for this which (on affected devices) does not set gpio_keys_button.gpio on these 2-in-1s, instead it gets the irq for the GPIO, configures it as IRQ_TYPE_LEVEL_LOW (to match how the _LID AML code configures it) and passes the irq in gpio_keys_button.irq.

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.
