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. Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=31339 Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
