The tsl2771 and tmd2771 devices create the in_proximity0_calibscale_available sysfs attribute. These two particular devices do not support changing the proximity gain value on the chip so this patch removes that sysfs attribute. As expected, these two devices already did not create the IIO_CHAN_INFO_CALIBSCALE channel and proximity0_calibrate sysfs attribute. Page 38 of the tsl2772 data sheet shows that the proximity gain can be adjusted with bits 2-3 on the control register: https://ams.com/eng/content/download/291503/1066377/file/TSL2772_DS000181_2-00.pdf Page 35 of the tsl2771 and tmd2771 data sheets shows that bits 2-3 on the control register are reserved and changing the proximity gain is not supported: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf https://ams.com/eng/content/download/250283/976077/file/TMD2771_DS000177_2-00.pdf Signed-off-by: Brian Masney <masneyb@xxxxxxxxxxxxx> --- drivers/staging/iio/light/tsl2x7x.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/staging/iio/light/tsl2x7x.c b/drivers/staging/iio/light/tsl2x7x.c index fb91c46c8747..8c29a52153c1 100644 --- a/drivers/staging/iio/light/tsl2x7x.c +++ b/drivers/staging/iio/light/tsl2x7x.c @@ -1477,7 +1477,6 @@ static struct attribute *tsl2x7x_ALSPRX_device_attrs[] = { &dev_attr_in_illuminance0_target_input.attr, &dev_attr_in_illuminance0_calibrate.attr, &dev_attr_in_illuminance0_lux_table.attr, - &iio_const_attr_in_proximity0_calibscale_available.dev_attr.attr, NULL }; -- 2.14.3 -- 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
