This series updates the driver for the veml6030 ALS and adds support for the veml6035, which shares most of its functionality with the former.
The most relevant updates for the veml6030 are the resolution correction to meet the datasheet update that took place with Rev 1.7, 28-Nov-2023, a fix to avoid a segmentation fault when reading the in_illuminance_period_available attribute, and the removal of the processed value for the WHITE channel, as it uses the ALS resolution.
Vishay does not host the Product Information Notification where the resolution correction was introduced, but it can still be found online[1], and the corrected value is the one listed on the latest version of the datasheet[2] (Rev. 1.7, 28-Nov-2023) and application note[3] (Rev. 17-Jan-2024).

Signed-off-by: Javier Carrasco javier.carrasco.cruz@gmail.com --- Changes in v2: - Rebase to iio/testing, dropping applied patches [1/7], [4/7]. - Drop [3/7] (applied to iio/fixes-togreg). - Add patch to use dev_err_probe() in probe error paths. - Add patch to use read_avail() for available attributes. - Add patches to use to support a regulator. - Add patch to ensure that the device is powered off in error paths after powering it on. - Add patch to drop processed values from the WHITE channel. - Use fsleep() instead of usleep_range() in veml6030_als_pwr_on() - Link to v1: https://lore.kernel.org/r/20240913-veml6035-v1-0-0b09c0c90418@gmail.com
