Subject: [PATCH 04/26] Staging: fbtft: flexfb: Switch to the gpio descriptor
 interface
Message-ID: <0bc27a5c4f06e50f9cc2d568c6ce5f983dc84925.1543142440.git.nishadkamdar@gmail.com>

User-Agent: Mutt/1.9.4 (2018-02-28)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This switches the flexfb.c to use GPIO descriptors
rather than numerical gpios.
