The driver for the as73211 light sensor provides the following not yet documented sysfs entries: - in_intensity_(x|y|z)_raw - in_intensity_(x|y|z)_scale - in_intensity_sampling_frequency(_available) - in_intensity_hardwaregain(_available) - in_intensity_integration_time Signed-off-by: Christian Eggers <ceggers@xxxxxxx> --- On Thursday, 6 August 2020, 19:44:51 CEST, Jonathan Cameron wrote: Hi Jonathan, > Hi Christian, > > I'll take this, but please send a follow up patch to add documentation > for in_intensity_x_raw and all the other new ABI this adds in > Documentation/ABI/testing/sysfs-bus-iio > I should have mentioned that earlier, but kind of assumed we already > had these documented for some reason! > [...] > Insert them into the relevant groups that already exist.

I added all sysfs entries which were not present in 5.8-rc6.
