As requested in [1], this is a preparatory series with some basic cleanups for the ad9467 and adi-axi-adc drivers. This means that the iio backend series [2] will depend on this one but hopefully we'll quickly get this one in.

We just want to go over the rows. - Link to v1: https://lore.kernel.org/r/20231205-iio-backend-prep-v1-0-7c9bc18d612b@xxxxxxxxxx --- Nuno Sa (8): iio: adc: ad9467: fix reset gpio handling iio: adc: ad9467: don't ignore error codes iio: adc: ad9467: add mutex to struct ad9467_state iio: adc: ad9467: fix scale setting iio: adc: ad9467: use spi_get_device_match_data() iio: adc: ad9467: use chip_info variables instead of array iio: adc: ad9467: use the more common !val NULL check iio: adc: adi-axi-adc: convert to regmap drivers/iio/adc/ad9467.c | 207 +++++++++++++++++++++++------------- drivers/iio/adc/adi-axi-adc.c | 159 ++++++++++++--------------- include/linux/iio/adc/adi-axi-adc.h | 4 + 3 files changed, 204 insertions(+), 166 deletions(-) --- base-commit: 5c8f90655a7bdb6232b2cea6503df16367b11a53 change-id: 20231205-iio-backend-prep-4d96ef364080 -- Thanks! - Nuno Sá
