When using a protocol v2 or v3 hardware, elantech uses the function elantech_report_semi_mt_data() to report data. This devices are rather creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid touch is reported. Anyway, userspace (libinput) is now confused by these (0,0) touches, and detect them as palm, and rejects them. Commit 3c0213d1 ("Input: elantech - fix semi-mt protocol for v3 HW") was sufficient enough for xf86-input-synaptics and libinput before it has palm rejection. Now we need to actually tell libinput that this device is a semi-mt one and it should not rely on the actual values of the 2 touches. Cc: stable@vger.kernel.org Signed-off-by:

As of e0361b70 ("Input: wacom_w8001 - split the touch and pen devices into two devices") the touch events aren't multiplexed over the same device anymore, the use of ABS_MT_TOOL_TYPE is superfluous. And even before then it only ever sent MT_TOOL_TYPE_FINGER anyway. Signed-off-by:

Commit 4ea14a53 ("Input: gpio-keys - report error when disabling unsupported key") tried let user know that they attempted to disable an unsupported key, unfortunately the check is wrong as it believes that all codes are invalid. Fix it by ensuring that keys that we try to disable are subset of keys (or switches) that device reports.

Commit da1f026b ("Keyboard: omap-keypad: use matrix_keypad.h") switched the driver to use matrix keypad infrastructure, which made array of keycodes to be unsigned short, and caused the test for negativity never trigger. This leads to the following static checker warning: drivers/input/keyboard/omap-keypad.c:158 omap_kp_tasklet() warn: 'keycodes[]' is never negative. Given that we did not care about this check for a few years already let's simply remove it. Reported-by:

Remove write to REG_IRQCLR and REG_IRQWAKEUP in interrupt handler for IRQENB_HW_PEN as the resume handler should and does clear REG_IRQWAKEUP. IRQENB_HW_PEN bit is set in irqclr so that all interrupts get cleared later so let IRQENB_HW_PEN be cleared by that. Without this patch wakeup events from TSC_ADC do not work because pending interrupts in TSC_ADC were causing HW_PEN interrupt, needed for wake from suspend modes, to get disabled immediately by IRQ handler after being enabled and preventing wake from happening.

Rework the uinput ABS validation to check passed absinfo data immediately, but do ABS initialization as last step in UI_DEV_CREATE. The behavior observed by user-space is not changed, as ABS initialization was never checked for errors. With this in place, the order of device initialization and abs configuration is no longer fixed. Userspace can initialize the device and afterwards set absinfo just fine. Signed-off-by:

This adds two new ioctls, UINPUT_DEV_SETUP and UI_ABS_SETUP, that replaces the old device setup method (by write()'ing "struct uinput_user_dev" to the node). The old method is not easily extendable and requires huge payloads. Furthermore, overloading write() without properly versioned objects is error-prone. Therefore, we introduce two new ioctls to replace the old method. These ioctls support all features of the old method, plus a "resolution" field for absinfo. Furthermore, it's properly forward-compatible to new ABS codes and a growing "struct input_absinfo" structure. UI_ABS_SETUP also allows user-space to skip unknown axes if not set. There is no need to copy the whole array temporarily into the kernel, but instead the caller issues several ioctl where we copy each value manually. Signed-off-by:

The goodix touchscreen driver uses a "rotated_screen" flag for systems on which the touchscreen is mounted rotated by 180 degrees with respect to the display. With the addition of support for the dt properties "touchscreen-inverted-x" and "touchscreen-inverted-y", a separate "rotated_screen" flag is not necessary anymore. This patch replaces it by setting the inverted_x and inverted_y flags instead. Signed-off-by:

Goodix devices can be configured by writing custom data to the device at init. The configuration data is read with request_firmware from "goodix_<id>_cfg.bin", where <id> is the product id read from the device (e.g.: goodix_911_cfg.bin for Goodix GT911, goodix_9271_cfg.bin for GT9271). The configuration information has a specific format described in the Goodix datasheet. It includes X/Y resolution, maximum supported touch points, interrupt flags, various sensitivity factors and settings for advanced features (like gesture recognition). Before writing the firmware, it is necessary to reset the device. If the device ACPI/DT information does not declare gpio pins (needed for reset), writing the firmware will not be available for these devices. This is based on Goodix datasheets for GT911 and GT9271 and on Goodix driver gt9xx.c for Android (publicly available in Android kernel trees for various devices). Signed-off-by:

After power on, it is recommended that the driver resets the device. The reset procedure timing is described in the datasheet and is used at device init (before writing device configuration) and for power management. It is a sequence of setting the interrupt and reset pins high/low at specific timing intervals. This procedure also includes setting the slave address to the one specified in the ACPI/device tree. This is based on Goodix datasheets for GT911 and GT9271 and on Goodix driver gt9xx.c for Android (publicly available in Android kernel trees for various devices). For reset the driver needs to control the interrupt and reset gpio pins (configured through ACPI/device tree). For devices that do not have the gpio pins properly declared, the functionality depending on these pins will not be available, but the device can still be used with basic functionality. For both device tree and ACPI, the interrupt gpio pin configuration is read from the "irq-gpios" property and the reset pin configuration is read from the "reset-gpios" property. For ACPI 5.1, named properties can be specified using the _DSD section. This functionality will not be available for devices that use indexed gpio pins declared in the _CRS section (we need to provide backward compatibility with devices that do not support using the interrupt gpio pin as output). For ACPI, the pins can be specified using ACPI 5.1: Device (STAC) { Name (_HID, "GDIX1001") ... Method (_CRS, 0, Serialized) { Name (RBUF, ResourceTemplate () { I2cSerialBus (0x0014, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\I2C0", 0x00, ResourceConsumer, , ) GpioInt (Edge, ActiveHigh, Exclusive, PullNone, 0x0000, "\\I2C0", 0x00, ResourceConsumer, , ) { // Pin list 0 } GpioIo (Exclusive, PullDown, 0x0000, 0x0000, IoRestrictionOutputOnly, "\\I2C0", 0x00, ResourceConsumer, , ) { 1 } }) Return (RBUF) } Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package (2) {"irq-gpios", Package() {^STAC, 0, 0, 0 }}, Package (2) {"reset-gpios", Package() {^STAC, 1, 0, 0 }}, ... } } Signed-off-by: -

Each of the Goodix devices supported by this driver has a fixed size for the configuration information registers. The size varies depending on the device and is specified in the datasheet. Use the proper configuration length as specified in the datasheet for each device model, so we do not read more than the actual size of the configuration registers. Signed-off-by:

PS/2 protocol is slow, and using it with pass-through port (where we encapsulate PS/2 into PS/2) is slower yet so it takes quite a bit of time to do full protocol discovery for device attached to a pass-through port. However, so far we have not see anything but trackpoints or basic PS/2 mice on pass-through ports, so let's limit protocols that we probe there to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol, and avoid other extended protocols, such as Synaptics, ALPS, etc. Reviewed-by:

In preparation of limiting protocols that we try on pass-through ports, let's rework initialization code and factor common code into psmouse_try_protocol() that accepts protocol type (instead of detec() function pointer) and can, for most protocols, perform both detection and initialization. Note that this removes option of forcing Lifebook protocol on devices that are not recognized by lifebook_detect() as having the hardware, but I do not recall anyone using this option. Reviewed-by:

When Cypress protocol support is disabled cypress_init() is a stub that always returns -ENOSYS, so there is not point in testing for CONFIG_MOUSE_PS2_CYPRESS after we decided that we are dealing with a Cypress device. Also, we should only be calling cypress_detect() when set_properties argument is "true", like with other protocols. There is a slight change in behavior to make follow-up patches more uniform: when we detect Cypress but its initialization fails, instead of immediately returning PSMOUSE_PS2 protocol we now continue trying IntelliMouse [Explorer]. Given that Cypress devices only have issue with Sentelic probes probing Imtellimouse should be safe. Reviewed-by:

Previously the "vendor" and "product" IDs for the elan_i2c driver simply reported 0000. This patch modifies the elan_i2c driver to include the Elan vendor ID and the touchpad's product id under input/input*/{vendor,product}. Specifically, this is to allow us to apply a generic Elan gestures config that will apply to all Elan touchpads on ChromeOS. These configs match to input devices in various ways, but one major way is by matching on vendor ID. Adding this patch allows the default Elan touchpad config to be applied to Elan touchpads in this kernel by matching on devices that have vendor ID 04f3. Note that product ID is also available via custom sysfs entry "product_id" as well. Signed-off-by:Charlie Mooney <charliemooney@chromium.org> Signed-off-by:
