Subject: [PATCH v7 0/5] Support for Avago APDS9306 Ambient Light Sensor

Support for Avago APDS9306 Ambient Light Sensor.

Driver support for Avago (Broadcom) APDS9306 Ambient Light Sensor.
It has two channels - ALS and CLEAR. The ALS (Ambient Light Sensor)
channel approximates the response of the human-eye providing direct
read out where the output count is proportional to ambient light levels.
It is internally temperature compensated and rejects 50Hz and 60Hz flicker
caused by artificial light sources. Hardware interrupt configuration is
optional. It is a low power device with 20 bit resolution and has 
configurable adaptive interrupt mode and interrupt persistence mode.
The device also features inbuilt hardware gain, multiple integration time
selection options and sampling frequency selection options.

This driver also uses the IIO GTS (Gain Time Scale) Helpers Namespace for 
Scales, Gains and Integration time implementation.

v6 -> v7:
 - Made comments to struct part_id_gts_multiplier as kernel doc
 - Removed static_asserts for array sizes
 - Moved regmap_field from driver private data structure and removed
   regfield_ prefix to reduce names
 - Used "struct apds9306_regfields *rf = &data->rf" in the respective
   functions to reduce names
 - Removed apds9306_runtime_power_on() and apds9306_runtime_power_off()
   functions in favour of using the runtime_pm calls directly from
   calling functions.
 - Fixed indentations

v2 -> v5:
 - Bumped up the version:
   RFC->v0->v1->v2->v3 (Earlier scheme)
   v1->v2->v3->v4->v5 (Scheme after review) (Current scheme)
   Link: https://lore.kernel.org/all/20231028143631.2545f93e@jic23-huawei/

 - Added separate patch to merge schemas for APDS9300 and APDS9906. Added
   APDS9306 support on top of that.
