From 914f05c8118e17d65c4626ae3ed2edcf79f00031 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 21 Mar 2012 08:03:28 -0300 Subject: [media] soc-camera: Support user-configurable line stride Add a capabilities field to the soc_camera_host structure to flag hosts that support user-configurable line strides. soc_camera_try_fmt() then passes the user-provided bytesperline and sizeimage format fields to such hosts, and expects the host to check (and fix if needed) the values.
