If we were to apply this to the existing sensors, how do we distinguish between 'clear' vs the visable+infrared option that is there already? I note below that you have distinguished this by saying it is on a colour sensor only. That seems a little bit inconsistent given a single wide band sensor might be measuring the same thing... I'm fine with the colour ones btw but one query below.. >> A trivial addition to industrialio-core.c is required. >> >> in_cct0_input will return typically return the color temperature >> expressed in kelvins. >> >> IIO_MODIFIERs are respective of the associated light frequencies for >> each of the channels. >> >> >> >> >> >> >> Signed-off-by: Jon Brenner<jbrenner@xxxxxxxxxxx> >> --- >> .../staging/iio/Documentation/sysfs-bus-iio-light | 46 >> ++++++++++++++++++++ >> 1 files changed, 46 insertions(+), 0 deletions(-) >> >> diff --git a/drivers/staging/iio/Documentation/sysfs-bus-iio-light >> b/drivers/staging/iio/Documentation/sysfs-bus-iio-light >> index 715c74d..bd42baf 100644 >> --- a/drivers/staging/iio/Documentation/sysfs-bus-iio-light >> +++ b/drivers/staging/iio/Documentation/sysfs-bus-iio-light >> @@ -34,6 +34,15 @@ Description: >> it comes back in SI units, it should also include _input else it >> should include _raw to signify it is not in SI units. >> >> +What: /sys/bus/iio/devices/device[n]/in_cct0[_input|_raw] >> +KernelVersion: 3.4.0 >> +Contact: linux-iio@xxxxxxxxxxxxxxx >> +Description: >> + This should return the correlated color temperature from the light >> +sensor.
