I am investigating the connection relationship between Kingfisher (* 1) and StarterKit (* 2). (* 1), B055 of 440p_ComExpress is named IrqEXT0xE8 and it is connected with INT of U11 (TCA9539QPWRQ1).
(* 2), B055 of 440p_ComExpress is named AVB_AVTP_MATCH / SCL5 and is connected to B11 (AVB_AVTP_MATCH_A) of R-Car SiP.
How will it work (how do you communicate) with B055 when connecting (* 1) and (* 2) together?

BACKGROUND:
When Kingfisher upgraded from M04 to M05, it seems that the connection has changed from A079 to B055, so I am investigating the reason.
