Subject: [PATCH 0/3] drm/bridge: dw_hdmi: allow to disable CEC from DT

Boards can have perfectly working DW HDMI CEC implementation but they
may prefer to use bit banged implementation instead. This is the
situation on Beelink X2.

Add DW HDMI DT property for disabling CEC. This prevents confusion on
userspace side by not exposing unused CEC interface.

Best regards,
Jernej
