this just fixes the comment; however, I'm not sure if the driver reports measurements correctly; the raw values are 0.3 uT / LSB; IIO is supposed to report magnetic fields in Gauss, so the scale should be around 1/300 (ignoring ASA) -- but value and scale are returned as VAL_INT Signed-off-by: Peter Meerwald <pmeerw@xxxxxxxxxx> --- drivers/iio/magnetometer/ak8975.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/magnetometer/ak8975.c b/drivers/iio/magnetometer/ak8975.c index 7105f22..ff284e5 100644 --- a/drivers/iio/magnetometer/ak8975.c +++ b/drivers/iio/magnetometer/ak8975.c @@ -263,7 +263,7 @@ static int ak8975_setup(struct i2c_client *client) * * HuT = H * 1229/4096, or roughly, 3/10. * - * Since 1uT = 100 gauss, our final scale factor becomes: + * Since 1uT = 0.01 gauss, our final scale factor becomes: * * Hadj = H * ((ASA + 128) / 256) * 3/10 * 100 * Hadj = H * ((ASA + 128) * 30 / 256 -- 1.8.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
