Subject: [PATCH v3 1/4] omapdrm: panel: fix compatible vendor string for td028ttec1
Date: Tue, 28 Nov 2017 16:48:54 +0100	[thread overview]
Message-ID: <6ae8f4b7d794c536650cc99025e5b026089cea30.1511884135.git.hns@goldelico.com> (raw)

In-Reply-To: <cover.1511884135.git.hns@goldelico.com>

The vendor name was "toppoly" but other panels and the vendor list
have defined it as "tpo". So let's fix it in driver and bindings.

We keep the old definition in parallel to stay compatible with
potential older DTB setup.
