I wouldn't hurt to provide a short description. 722 has 3 functions, what about 721?
Okay, I'll add short description here in next v3-patch.

return true;That tells us it has 3 functions (jack, mic, amp), so what's different to RT722? could we have a single driver for both parts? A lot of this driver seems copy-pasted-renamed.
RT721 has 3 functions just like RT722, but it's still a different codec and from internal discussion, we think it's better to separate the driver for future code management.

It seems we still need it to be set as latest upsteam code still need it. If the upstream code is updated regarding to this, we'll do the modification to it.

It seems odd to hard-code all this, no?
It seems there is no api or function to support blind write from ACPI from latest upstream code, and we think it's easier for us to manage the different function's blind write.

Same reply as above one.
+enum rt721_sdca_jd_src {
RT721_JD_NULL,RT721_JD1,RT721_JD2,+};
is this supported in SDCA? I can't recall seeing this for other drivers.
I'll remove this in next patch.
