Amlogic G12A embeds 2 CEC controllers : - AO-CEC-A the same controller as in GXBB, GXL & GXM SoCs - AO-CEC-B a new controller
Note, the two controller can work simultanously since 2 Pads can handle CEC, thus this SoC can handle 2 distinct CEC busses. This patch adds the nodes for the AO-CEC-A controller until AO-CEC-B is supported.
