The mma8452_driver declares both of_match_table and i2c_driver.id_table match-tables, but its probe() function only checked for of matches. Add support for i2c_device_id matches. This fixes the driver not loading on some x86 tablets (e.g. the Nextbook Ares 8) where the i2c_client is instantiated by platform code using an i2c_device_id. Drop of_match_ptr() protection to avoid unused warning. Fixes: c3cdd6e4 ("iio: mma8452: refactor for seperating chip specific data") Signed-off-by:

The atmel,trigger-edge-type was never imposed by the driver. Make things right and remove this property from the mandatory list. This will not break existing nodes because according to the binding they should have this property. However, the driver does not impose it and it works without it, the property selects the trigger type, and without it, the driver will have no trigger available, which is the case on some boards which do not have access to the trigger pin. This will avoid generating this warning for example: */arch/arm/boot/dts/at91-sama7g5ek.dt.yaml: adc@e1000000: 'atmel,trigger-edge-type' is a required property From schema: */Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml Signed-off-by:

When a consumer calls iio_read_channel_processed() and no channel scale is available, it's assumed that the scale is one and the raw value is returned as expected. On the other hand, if the consumer calls iio_convert_raw_to_processed() the scaling factor requested by the consumer is not applied. This for example causes the consumer to process mV when expecting uV. Make sure to always apply the scaling factor requested by the consumer.

Also the PROXSTAT bit (3) is for channel 1 (PHM, Phase Measured), not (PHR, Phase Reference, channel 0), so the offset is 2 instead of 3.
