Ah, that explains what it is. Sorry, use in_proximitiy0_sampling_frequency to provide equivalent control please. Might be a pain here, but this interface will just provide the same info as the existing one in a different form. Note that sampling_frequency is documented as a general one, but can be extended to individual channels. Actually add it to the iio-core as an element in the info_mask as I doubt this will be the last time we see this control. This will need to be a precursor patch to the driver obviously. IIO_CHAN_INFO_SAMP_FREQ and the relevant shared and separate macros need to go in iio.h + the text entry in industrialio-core.c If you like I can do this but it'll be quicker if you do :) From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jonathan Cameron Subject: Re: [PATCH V2 2/2] staging: Documentation: add proximity_sampling_period as sysfs details Date: Thu, 12 Apr 2012 10:37:47 +0100 Message-ID: <4F86A26B.1090209@cam.ac.uk> References: <1334214492-23044-1-git-send-email-ldewangan@nvidia.com> <1334214492-23044-3-git-send-email-ldewangan@nvidia.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1334214492-23044-3-git-send-email-ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org> Sender: linux-iio-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Laxman Dewangan Cc: gregkh-hQyY1W1yCW8ekmWlsbkhG0B+6BGkLq7r@public.gmane.org, grant.likely-s3s/WqlpOiPyB63q8FvJNQ@public.gmane.org, rob.herring-bsGFqQB8/DxBDgjK7y7TUQ@public.gmane.org, jbrenner-yYKgigLBUwlBDgjK7y7TUQ@public.gmane.org, rklein-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org, max-U9r9yeDMy7A@public.gmane.org, linux-iio-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devel-gWbeCf7V1WCQmaza687I9mD2FQJk+8+b@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-discuss-uLR06cmDAlY/bJ5BZ2RsiQ@public.gmane.org List-Id: devicetree@vger.kernel.org On 4/12/2012 8:08 AM, Laxman Dewangan wrote: > Add the sysfs proximity_sampling_period for sampling period of > proximity sensing. > > Signed-off-by: Laxman Dewangan > --- > .../staging/iio/Documentation/sysfs-bus-iio-light | 7 +++++++ > 1 files changed, 7 insertions(+), 0 deletions(-) > > diff --git a/drivers/staging/iio/Documentation/sysfs-bus-iio-light b/drivers/staging/iio/Documentation/sysfs-bus-iio-light > index edbf470..9d6108b 100644 > --- a/drivers/staging/iio/Documentation/sysfs-bus-iio-light > +++ b/drivers/staging/iio/Documentation/sysfs-bus-iio-light > @@ -83,3 +83,10 @@ Description: > Hardware or software applied calibration scale factor assumed > to account for attenuation due to industrial design (glass > filters or aperture holes). > + > +What: /sys/bus/iio/devices/device[n]/proximity_sampling_period > +KernelVersion: 3.5 > +Contact: linux-iio-u79uwXL29TY76Z2rM5mHXA@public.gmane.org > +Description: > + Hardware dependent mode for proximity sensor device to set/get > + the sampling rate of proximity sensing and conversion.
