Subject: [PATCH 04/26] Staging: fbtft: flexfb: Switch to the gpio descriptor interface
Date: Sun, 25 Nov 2018 16:56:29 +0530	[thread overview]
Message-ID: <0bc27a5c4f06e50f9cc2d568c6ce5f983dc84925.1543142440.git.nishadkamdar@gmail.com> (raw)
In-Reply-To: <cover.1543142440.git.nishadkamdar@gmail.com>

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