The audio card uses loongson I2S controller present in 7axxx/2kxxx chips to transfer audio data.
On loongson platform, the chip has only one I2S controller.

I got 2 copies of this patch, but none of the rest of the series appears to be threaded with it.

Reviewing sound stuff is beyond my pay grade, so forgive me if I am off the rails here, but this (and the "x"s in the description) look a bit odd. Recently, we've noticed quite a few loongson dt-bindings attempting to use a single compatible for many different chips. Usually you have individual compatibles for the various SoCs with this core, which can fall back to a generic one, rather than just adding a generic compatible for all devices. As far as I know, there's several SoCs fitting 2kxxx, and the format being used elsewhere is "loongson,ls2k1000" etc.
Currently, Loongson has 2K0500/2K1000LA/2K1500/2K2000 chips.
Here, its' possible to use a single compatible for different chips,
as the audio device is a logical device, not dependent on chip model.
Cheers, Conor.
