Subject: [PATCH 5/7] iio: light: veml6030: update sensor resolution
Date: Fri, 13 Sep 2024 15:19:00 +0200	[thread overview]
Message-ID: <20240913-veml6035-v1-5-0b09c0c90418@gmail.com> (raw)
In-Reply-To: <20240913-veml6035-v1-0-0b09c0c90418@gmail.com>

The driver still uses the sensor resolution provided in the datasheet
until Rev. 1.6, 28-Apr-2022, which was updated with Rev 1.7,
28-Nov-2023. The original ambient light resolution has been updated from
0.0036 lx/ct to 0.0042 lx/ct, which is the value that can be found in
the current device datasheet.

Update the default resolution for IT = 100 ms and GAIN = 1/8 from the
original 4608 mlux/cnt to the current value from the "Resolution and
maximum detection range" table (Application Note 84367, page 5), 5376
mlux/cnt.
