Luca Ceresoli authored
The irq-gpios description misleading, apparently saying that driving the IRQ GPIO resets the device, which is even more puzzling as there is a reset GPIO as well. In reality the IRQ pin can be driven during the reset sequence to configure the client address, as it becomes clear after checking both the datasheet and the driver code. Improve the text to clarify that. Also rephrase to remove reference to the driver, which is not appropriate in the bindings.

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.

While input core can work with input->phys set to NULL userspace might depend on it, so better fail probing if allocation fails. The system must be in a pretty bad shape for it to happen anyway.

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 d6df7df7 ("ARM: pxa: remove unused board files"), so let's remove it.

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.comSigned-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

This patch adds support for each available OTP variant of the device. The OTP configuration cannot be read over I2C, so it is derived from a compatible string instead. Early revisions of the D0 order code require their OTP-enabled func- tionality to be manually restored following a soft reset; this patch accommodates this erratum as well.

This patch adds bindings for the D0 order code of the device. This order code represents an OTP variant that enables a touch-and-hold function in place of slider 1. Also included is the ability to specify the 00 order code (default option with no OTP customization) explicitly.

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).

Simplify probe() by replacing of_match_node() for retrieving match data by device_get_match_data(). Some minor cleanups: * Remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing. * Move OF table near to the user. * Arrange variables in reverse xmas tree order in probe().

The driver supports passing some GPIO lines for rows and columns through the driver data, but there is no in-kernel user of this. Further the use seems convoluted because the GPIO lines are unused in the driver, then explicitly free:ed when removing it without being requested when probing it, which is assymetric and just a recepie for disaster. Remove the support for these unused GPIOs, if need be support can be reestablished in an organized fashion using GPIO descriptors.

The cap11xx devices have three hardware identification registers which are currently marked as volatile, preventing caching of those registers. This is not ideal since the registers should never change at runtime, we should be able to cache the value after the first read. Stop marking the registers as volatile, we don't have register defaults specified in the driver so this will result in reading from the hardware on first use.
