From: Marc Ferland <marc.ferland@xxxxxxxxxxxx> For temperature readings, the remainder is returned as nano Celsius _but_ we mark it as IIO_VAL_INT_PLUS_MICRO. This results in incorrect temperature reporting through hwmon for example. I have a board here which reports the following when running 'sensors': iio_hwmon-isa-0000 Adapter: ISA adapter temp1: +93.3°C With the patch applied, it returns the correct temperature: iio_hwmon-isa-0000 Adapter: ISA adapter temp1: +30.5°C Signed-off-by: Marc Ferland <marc.ferland@xxxxxxxxxxxx> --- drivers/iio/dac/ad5592r-base.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/dac/ad5592r-base.c b/drivers/iio/dac/ad5592r-base.c index 076bc9ecfb49..4763402dbcd6 100644 --- a/drivers/iio/dac/ad5592r-base.c +++ b/drivers/iio/dac/ad5592r-base.c @@ -415,7 +415,7 @@ static int ad5592r_read_raw(struct iio_dev *iio_dev, s64 tmp = *val * (3767897513LL / 25LL); *val = div_s64_rem(tmp, 1000000000LL, val2); - return IIO_VAL_INT_PLUS_MICRO; + return IIO_VAL_INT_PLUS_NANO; } mutex_lock(&st->lock); base-commit: 98369dccd2f8e16bf4c6621053af7aa4821dcf8e -- 2.34.1
