From 50155c25bf346b65fec8e215131df397b0a5ee6e Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Wed, 22 Dec 2010 17:31:59 -0300 Subject: [PATCH] [media] fsl_viu: add VIDIOC_QUERYSTD and VIDIOC_G_STD support VIDIOC_QUERYSTD and VIDIOC_G_STD ioctls are currently not supported in the FSL VIU driver. The decoder subdevice driver saa7115 extended by previous patch supports QUERYSTD for saa711x, so we add the appropriate ioctls to the VIU driver to be able to determine the video input's standard.
