From db07c5ca5596901a9723245c0068668a7f2403c6 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 17 Oct 2018 07:05:41 -0400 Subject: [PATCH] media: cec: add debug_phys_addr module option If debug_phys_addr is set, then CEC_CAP_PHYS_ADDR is added to the CEC adapter capabilities. This allows for testing CEC even if the physical address isn't set. This makes it possible to connect two HDMI outputs together and still use CEC. Very useful for testing CEC if you don't have access to an HDMI receiver under linux.
