Patch 1 adds the devicetree binding. Patch 2 adds the IIO driver, which exposes the proximity reading and a configurable integration time. Tested on Orange Pi Zero 2W. Changes in v2: - dt-bindings: Collect Reviewed-by from Krzysztof. - driver: Address review comments from Andy: - Use a Datasheet: tag in the commit message. - Drop mod_devicetable.h, sort the includes and include what is used. - Drop the i2c_client pointer from the private data and use regmap_get_device() instead. - Drop the unused i2c_set_clientdata(). - Enable a maple regmap cache, mark PS_DATA and DEV_ID volatile. - Rework the integration time validation in write_raw(). - Use reverse xmas tree order for local variables. - Document the power-up delay and use 3 * USEC_PER_MSEC. - Warn and continue on an unknown device ID instead of failing. - Join lines that fit within 100 columns. - Simplify the Assisted-by tag. - driver: Drop the i2c_check_functionality() call, as devm_regmap_init_i2c() already checks the adapter capabilities.
