ROHM BU79100G is a 12-bit, single channel ADC. From the software point of view it is identical to the TI's ADS7866. Support reading ADC measurements using the ad7476.c Signed-off-by: Matti Vaittinen --- Please, see the relevant discussion (as to why an ID for a fallback is added) in: https://lore.kernel.org/all/f8ec547a-5924-4563-aa1d-dde8227844fa@gmail.com/ This patch was based on v6.15-rc1. I can rebase if needed. drivers/iio/adc/ad7476.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/drivers/iio/adc/ad7476.c b/drivers/iio/adc/ad7476.c index 37b0515cf4fc..d48ee8f1d547 100644 --- a/drivers/iio/adc/ad7476.c +++ b/drivers/iio/adc/ad7476.c @@ -435,6 +435,13 @@ static const struct spi_device_id ad7476_id[] = { { "ads7866", ID_ADS7866 }, { "ads7867", ID_ADS7867 }, { "ads7868", ID_ADS7868 }, + /* + * The ROHM BU79100G is identical to the TI's ADS7866 from the software + * point of view.
