[PATCH v3 00/15] iio: chemical: bme680: Driver cleanup

From: Vasileios Amoiridis
Date: Sun Jun 09 2024 - 19:38:41 EST


Based on fixes-togreg as the 4 first commits are already applied

Patch 1/15: Added comment for explanation of what mutex is used for

Patch 2/15: Removed fixes tag

Patch 3-15/15: Reworded the commit messages to come close to convention
of 75 chars per line.

v2: https://lore.kernel.org/linux-iio/20240606212313.207550-1-vassilisamir@xxxxxxxxx/

Patch 4/19:
- Combined the bme680_conversion_time_us() and bme680_wait_for_eoc()
into one function.
- Added better comment for the calculation.
- Added checks in the bme680_wait_for_eoc() function.

Patch 5/19:
- Fixed typo in commit message.

Patch 6/19:
- Added a fixes tag since without the mutexes, read operations can be
broken.

Patch 10/19:
- Converted shifting operation to FIELD_GET()

Patch 11/19:
- Changed convention from &data->bufer[0] to data->buffer.
- Removed IIO_DMA_MINALIGN as it is not needed anymore.

Patch 13/19:
- Removed IIO_DMA_MINALIGN

Patch 14/19:
- Splitted from Patch v1 14/19

Patch 15/19:
- Splitted from Patch v1 14/19

Patch 16/19: **NEW**
- Use dev_err_probe() where applicable.

v1: https://lore.kernel.org/linux-iio/20240527183805.311501-1-vassilisamir@xxxxxxxxx/

This started as a series to add support for buffers and the new
BME688 but it ended up being just a cleaning series. These might
be quite some patches for such a thing but I feel that they are
are well split, in order to allow for better review.

The patches are mostly small changes but essential for the correct use
of the driver. The first patches looked like fixes that should be
marked for the stable. Patches [11,17/17] might be a bit bigger but 11/17
is quite straightforward and 17/17 is basically a duplication of a
very similar commit coming from the BMP280 driver [1].

In general, the datasheet [2] of the driver is not very descriptive,
and it redirects the user to the BME68x Sensor API [3]. All the things
that were identified from the BME68x Sensor API have been marked with
links to the original locations of the GitHub code. If this is too much
and we don't want this type of information on the commit message, please
let me know and I will fix it.
