From 4a31a93a71e9d5d32945aa6f9a5de59ce3be2b94 Mon Sep 17 00:00:00 2001 From: Mats Randgaard Date: Tue, 10 Dec 2013 09:45:00 -0300 Subject: [PATCH] [media] adv7604: add support for all the digital input ports The adv7604 supports four digital input ports. This patch adds support for all of them, instead of just port A.
