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> 2023-05-23T00:28:16+00:00 Ismael Ferreras Morezuelas swyterzone@gmail.com 2023-05-23T00:21:07+00:00 urn:sha1:9284d3b9a3609db30a528947ec4e5178055cd268 The Linux kernel is notorious for misspelling X-Box, X-box, XBox or XBOX; the official spelling is actually just Xbox. Plain and simple. Tried to respect the existing notes but still following the style guide. No functional changes intended. This only affects ancillary parts.
