Please note that HDMI I2S has usable 4 I2S lanes, since HDMI supports 8 channel audio. As Marcus said, other blocks probably support them too, they are just not wired out on pins.

Should we change compatible for HDMI?

Best regards,
Jernej

I've dropped those patches for now.

I guess, another way of doing things if they are strictly identical but for the number of lanes they support would be to add a DT property for that number of lanes.

That's fine...I'll look into adding a dt property and how we would map channels to lanes.
Do you know of any examples?,

Grepping for of_property_read_u32 should give you plenty of examples :)
