On the Amlogic SoCs, the DW-HDMI HW support is here but the DW-HDMI CEC signal is not connected to a physical pin, leading to confusion when the dw-hdmi cec controller can't communicate on the bus. Disable it to avoid exposing a non-functinal bus. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> --- drivers/gpu/drm/meson/meson_dw_hdmi.c | 1 + 1 file changed, 1 insertion(+)
