Add support for the ON Semiconductor NB7VPQ904M Type-C USB SuperSpeed
and DisplayPort ALT Mode Linear Redriver chip found on some devices
with a Type-C port.
The redriver compensates ultra High-Speeed DisplayPort and USB
Super Speed signal integrity losses mainly due to PCB & transmission
cables.
The redriver doesn't support SuperSpeed lines swapping, but
can support Type-C SBU lines swapping.

I get the following build error on my system with this applied:
CC [M] drivers/usb/typec/mux/nb7vpq904m.o
drivers/usb/typec/mux/nb7vpq904m.c: In function ‘nb7vpq904m_register_bridge’:
drivers/usb/typec/mux/nb7vpq904m.c:327:20: error: ‘struct drm_bridge’ has no member named ‘of_node’
327 | nb7->bridge.of_node = nb7->client->dev.of_node;

What went wrong?
DRM bridge attach should be protected by #ifdef CONFIG_OF aswell, I'll send a v4 with such fix.
Thanks for the report,
Neil
