add support for mt6797 playback and capture
to MediaTek sound codec,
through MediaTek Proprietary audio interface.
add memory interface as FE dai.
add ADDA interface as BE dai.

Again this looks pretty good, some small comments but nothing major:

This looks like a switch statement.

Is there any reason for not implementing this as a mute_stream()
callback?  That'll keep the DAI muted during startup and before teardown
which will do the most to avoid any noise making it into the output.

This unconditionally returns IRQ_HANDLED even if we didn't get an
interrupt - it's better to return IRQ_NONE unless we actually handled
something since that is more robust if something goes wrong, it lets the
IRQ core shut up interrupts that get latched on and works with shared
interrupts if any future designs do that.

We used to avoid the pop sound from user space by closing hw path from outside to inside.
The control here is just to avoid the state is leaved in muted state.
I'll take a look at the mute_stream() though.

this IRQ num is not shared with other module, it's only for audio.
We error handle by clearing the all the irq status again, when
interrupts is sent but status not matched. we consider this handled?

I'm concerned if returing IRQ_NONE, will i no longer be able
to receive irq from this irq line?
Thanks

Right, that's the goal of mute_stream() too - it's the last thing we do
during startup and first thing we do on tear down so that there's less
chance of any noise making its way out of the DAI.  If it doesn't work
for your system it's fine to do this though.

In current designs...

You should at least complain somewhere if you get an interrupt that the
driver doesn't know how to handle.

> to receive irq from this irq line?

Well, that's kind of the goal in a way - if what's going wrong is
something that's just going to keep flagging the interrupt up then
the system will just get stuck handling the interrupt constantly which
is especially nasty if the interrupt is just silently acknowledged.  If
you return IRQ_NONE eventually the core will decide that the interrupt
is stuck and disable it which contains whatever the problem is.  I'd at
least put some logging in there so if something goes wrong there's an
obvious indication that something's gone wrong with the interrupt.
