I see.
* struct cros_typec_altmode_node, used by cros_ec_typec.c.
* struct cros_typec_data, used by cros_ec_typec.c and cros_typec_vdm.c.
* struct cros_typec_port, used by cros_ec_typec.c and cros_typec_vdm.c.
cros_typec_switch.c has another struct cros_typec_port.
To simplify, I'm not sure whether we should merge cros_ec_typec.h,
cros_typec_vdm.c, and cros_typec_vdm.h into cros_ec_typec.c.
Back to struct cros_typec_dp_bridge, I think it's fine to keep it as is.

I see.
