Please stop using the meaningless MTK_DRIVE_(x)mA macro.
drive-strength = <8>; is enough :-)

You don't need to change this compatible, as the only thing that changes in the
actual driver are the dapm_routes. I implemented support for that nice dai-link
(standard, kind of) graph so that we stop getting a thousand compatibles for no
reason other than routing :-)
This should work with (99.9% confident it will, but please test):
model = "mt8186_rt5650";
status = "okay";

This property is already set in the node that you're inheriting from
mt8186-corsola.dtsi, please drop.

Empty nodes are meaningless (and you're inheriting this dai link from

Why is this set to EV_ACT_ANY on Chinchou but not on the other Corsola devices?
Is there any specific reason?
