2024-01-20Input: remove usage of the deprecated ida_simple_xx() APIChristophe JAILLET1-8/+6
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So a -1 has been added when needed.

This driver does not use the SPI core as it should, instead tampering with the SSP registers manually. Refactoring the driver is almost certainly not worth it as the hardware seems to have been designed for and used only in the HP iPAQ hx4700 removed more than a year ago in d6df7df7ae5a ("ARM: pxa: remove unused board files"), so let's remove it.

2024-01-09Input: driver for Adafruit Seesaw GamepadAnshul Dalal4-0/+333
Adds a driver for a mini gamepad that communicates over i2c, the gamepad has bidirectional thumb stick input and six buttons. The gamepad chip utilizes the open framework from Adafruit called 'Seesaw' to transmit the ADC data for the joystick and digital pin state for the buttons. I have only implemented the functionality required to receive the thumb stick and button state. Steps in reading the gamepad state over i2c: 1. Reset the registers 2. Set the pin mode of the pins specified by the `BUTTON_MASK` to input `BUTTON_MASK`: A bit-map for the six digital pins internally connected to the joystick buttons. 3. Enable internal pullup resistors for the `BUTTON_MASK` 4. Bulk set the pin state HIGH for `BUTTON_MASK` 5. Poll the device for button and joystick state done by: `seesaw_read_data(struct i2c_client *client, struct seesaw_data *data)` Product page: https://www.adafruit.com/product/5743 Arduino driver: https://github.com/adafruit/Adafruit_Seesaw Driver tested on RPi Zero 2W Reviewed-by: Thomas Weißschuh <linux@weissschuh.net> Signed-off-by: Anshul Dalal <anshulusr@gmail.com> Link: https://lore.kernel.org/r/20240106015111.882325-2-anshulusr@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2024-01-01Input: iqs269a - add support for slider gesturesJeff LaBundy1-29/+191
This patch adds support for slider gestures that can be expressed by the device. Each gesture (e.g. tap or hold) can be mapped to a unique keycode for either slider 0 or 1. With this change, raw slider coordinates are reported only if the slider has no keycodes defined. This prevents unwanted mouse cur- sor movement when expressing axial gestures (e.g. swipe) and also eliminates some unnecessary I2C traffic. Different revisions of silicon use different tap and swipe timeout step sizes. Apply an appropriate scaling factor depending on which revision is found. To facilitate this change, store the iqs269_ver_info struct in the driver's private data so that other functions can use it after the driver has probed. Last but not least, a former reserved field in iqs269_ver_info now contains useful information; give it a name (fw_num).

2023-11-30Input: gpio-keys - add system suspend support for dedicated wakeirqsTony Lindgren2-4/+67
Some SoCs have a separate dedicated wake-up interrupt controller that can be used to wake up the system from deeper idle states. We already support configuring a separate interrupt for a gpio-keys button to be used with a gpio line. However, we are lacking support system suspend for cases where a separate interrupt needs to be used in deeper sleep modes. Because of it's nature, gpio-keys does not know about the runtime PM state of the button gpios, and may have several gpio buttons configured for each gpio-keys device instance. Implementing runtime PM support for gpio-keys does not help, and we cannot use drivers/base/power/wakeirq.c support. We need to implement custom wakeirq support for gpio-keys. For handling a dedicated wakeirq for system suspend, we enable and disable it with gpio_keys_enable_wakeup() and gpio_keys_disable_wakeup() that we already use based on device_may_wakeup(). Some systems may have a dedicated wakeirq that can also be used as the main interrupt, this is already working for gpio-keys. Let's add some wakeirq related comments while at it as the usage with a gpio line and separate interrupt line may not be obvious.

2023-11-29dt-bindings: input: mediatek,pmic-keys: Drop incomplete exampleRob Herring1-23/+1
The example for the Mediatek PMIC keys is incomplete as the binding is the full PMIC, not just the sub-functions. It is preferred for MFD examples to be complete in the top-level MFD device binding rather than piecemeal in each sub-function binding. This also fixes an undocumented (by schema) compatible warning for "mediatek,mt6397".

2023-10-29Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()Dan Carpenter1-1/+1
The put_device() calls rmi_release_function() which frees "fn" so the dereference on the next line "fn->num_of_irqs" is a use after free. Move the put_device() to the end to fix this.

2023-10-27Input: cyttsp5 - add handling for vddio regulatorLin, Meng-Bo1-7/+12
The Cypress touchscreen controllers are often used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Implement support for a "vddio-supply" that is enabled by the cyttsp5 driver so that the regulator gets enabled when needed.
