Message-Id: <1532343772-27382-29-git-send-email-todor.tomov@linaro.org>
Date: Mon, 23 Jul 2018 14:02:45 +0300
From: Todor Tomov <todor.tomov@...aro.org>
To: mchehab@...nel.org, sakari.ailus@...ux.intel.com,
hans.verkuil@...co.com, laurent.pinchart+renesas@...asonboard.com,

Cc: linux-kernel@...r.kernel.org, Todor Tomov <todor.tomov@...aro.org>
Subject: [PATCH v3 28/35] media: camss: vfe: Add support for UYVY output from VFE on 8x96
Add support to output UYVY formats from the VFE (via the PIX interface).
A configuration for the realign module in the VFE is added. As the
realign module is present on 8x96 but not on 8x16, this is supported
on 8x96 only.
