Convert Samsung SoC Keypad bindings to DT schema with changes: 1. Rename "linux,keypad-no-autorepeat" property to "linux,input-no-autorepeat", because the latter was implemented in the Linux driver. 2. Add clocks and clock-names, already used by DTS and the Linux driver. Signed-off-by:

Since commit 43a7206b ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the input_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.

Imagis IST3038B is another variant of Imagis IST3038 IC, which has a different register interface from IST3038C (possibly firmware defined). This should also work for IST3044B (though untested), however other variants using this interface/protocol(IST3026, IST3032, IST3026B, IST3032B) have a different format for coordinates, and they'd need additional effort to be supported by this driver.

In a follow-up patch implementation of the LED audio trigger will be moved to sound/core/snd_ctl_led, including removal of config symbol LEDS_AUDIO_TRIGGER. Also as of today the audio mute LED trigger is effectively a no-op w/o config symbol SND_CTL_LED being defined. Therefore switch the dependency to this config symbol. Suggested-by:

Add initial support for the new Goodix "Berlin" touchscreen ICs over the SPI interface. The driver doesn't use the regmap_spi code since the SPI messages needs to be prefixed, thus this custom regmap code. This initial driver is derived from the Goodix goodix_ts_berlin available at [1] and [2] and only supports the GT9916 IC present on the Qualcomm SM8550 MTP & QRD touch panel. The current implementation only supports BerlinD, aka GT9916. [1] https://github.com/goodix/goodix_ts_berlin [2] https://git.codelinaro.org/clo/la/platform/vendor/opensource/touch-driversReviewed-by:

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. Signed-off-by:

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:
