Subject: [PATCH v4 07/10] media: staging: rkisp1: rsz: enumerate the formats on the src pad according to the capture
Date: Tue,  1 Sep 2020 13:16:09 +0200	[thread overview]
Message-ID: <20200901111612.10552-8-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20200901111612.10552-1-dafna.hirschfeld@collabora.com>

Currently the resizer outputs the same media bus format
as the input. This is wrong since the resizer is also used
to downscale YUV formats. This patch changes the enumeration
of the supported formats. The supported formats on the sink pad
should be taken from the isp entity and the supported formats on
the source pad should be taken from the capture entity.
