From fb939dfcf2a3a70357000617799925b6a11f9348 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 8 Nov 2010 16:08:29 +0000 Subject: drm/radeon/kms: add support for clock/data path routers This is a follow on to: 26b5bc986423cf3887e09188cb662ed651c5374d (drm/radeon/kms: add support for router objects) That patch added support for systems that use a mux to control the ddc line routing between the connectors. This patch adds support for systems that use a mux to control the encoder clock and data path routing to the connectors.
