Subject: [Patch 12/13] media: am437x-vpfe: Remove per bus width static data
Date: Mon, 9 Sep 2019 11:27:42 -0500	[thread overview]
Message-ID: <20190909162743.30114-13-bparrot@ti.com> (raw)
In-Reply-To: <20190909162743.30114-1-bparrot@ti.com>

The bus related static data include in the vpfe_fmt
static table can be derived dynamically instead.
This simplify the table and it's use.

We instead replace the per bus data info with just
the usual bit per pixel value for each supported
pixel format.
