From d5f74a1eff9aef3ba23673c8ef74719ba8a105f7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Tue, 21 Apr 2020 15:57:41 +0200 Subject: [PATCH] media: rcar-vin: Make use of V4L2_CAP_IO_MC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Set the V4L2_CAP_IO_MC capability flag and remove the driver specific vidioc_enum_input, vidioc_g_input and vidioc_s_input callbacks for the media controller enabled part of the driver. Also add support mbus_code filtering for format enumeration.
