From: Hugues Fruchet Date: Thu, 8 Feb 2018 11:00:45 +0000 (-0500) Subject: media: stm32-dcmi: add g/s_parm framerate support X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=aebd90aa3244e3539001919dcfbf00027d5ab63c;p=openwrt%2Fstaging%2Fblogic.git media: stm32-dcmi: add g/s_parm framerate support Add g/s_parm framerate support by calling subdev g/s_frame_interval ops. This allows user to control sensor framerate by calling ioctl G/S_PARM.
