Hi, jermoe
Considering that the sample rate is up to 176.4K
PLL0 270.950400M max support 24bit *176.4k, 32ch for tdm mode
Perhaps PLL1 PLL1 calculation error , it should be set up 361.2672M for
32bit * 176.4k * 32ch.
In fact, most situations are limited by the speed of the IO pin.
Can we remove MPLL1 here and keep MPLL0?

That's not really the question here and there are interfaces (internal
for example) for which it can go higher than that.

... again, no everything goes through those pins.

That's up to you really. I'm merely pointing out that out of the 3 clock
sources, 2 are setup to serve derivative of 44.1kHz, which is useless.

Yes, if the number of tdm slots is smaller, theoretically it is possible
to support a higher sample rate.

Two PLLs are indeed unnecessary. I will remove one in next version. thanks
