There is no evidence of officially registered ACPI IDs for these devices. Thus, revert ACPI support from the driver. All authors of the respective changes are being informed here: d5c94568 ("iio: add bmp280 pressure and temperature driver") 6dba72ec ("iio: pressure: bmp280: add support for BMP180") 14beaa8f ("iio: pressure: bmp280: add humidity support") Above seems a cargo cult without paying attention to how ACPI IDs are being allocated.

It is implied that 'read' will read the first n bytes and not e.g. bytes only from offsets within the buffer that are a prime number. This change is non-functional, mostly just a rename. A secondary intent with this patch is to make room later to add a write callback. Signed-off-by:

The dmaengine buffer has some length alignment requirements that can differ from platform to platform. If the length alignment requirements are not met unexpected behavior like dropping of samples can occur. Currently these requirements are not reported and applications need to know the requirements of the platform by some out-of-band means. Add a new buffer attribute that reports the length alignment requirements called `length_align_bytes`. The reported length alignment is in bytes that means the buffer length alignment in sample sets depends on the number of enabled channels and the bytes per channel. Applications using this attribute to determine the buffer size requirements need to consider this. Signed-off-by:

Since the orginal scope of the driver was to only support the pH product from Atlas it has evolved to other sensors. Rename the file, driver name, and regmap to atlas-sensor which reflects this, although keep CONFIG_ATLAS_PH_SENSOR to not cause regressions with current configurations. Signed-off-by:

This chip is similar to the LTC2497 ADC, it just uses SPI instead of I2C and so has a slightly different protocol. Only the actual hardware access is different. The spi protocol is different enough to not be able to map the differences via a regmap. Also generalize the entry in MAINTAINER to cover the newly introduced file. Signed-off-by:

This allows to share most of this driver for the ltc2496 driver added in the next commit that is an SPI variant of the ltc2497. Initially I named the generic part ltc249x, but wild card names are frowned upon, so the generic part is called ltc2497-core even though it's not obvious that this is then to be reused for the ltc2496 driver.
