As we are moving away from platform to DT, we cant rely on the board

I don't understand this changelog. The board file never did this. The driver
enables the clock in the startup() callback.
My bad.
I couldn't get the ci20 audio to work without this change.
I double checked. The clock is indeed enabled.
But the rate needs to be set for the ci20.
clk_set_rate(i2s->clk_i2s, 12000000);
Where should I put it? I couldn’t trace how the rate is set for the jz4740..
There is no support for specifying clock rate defaults in the devicetree
itself. See commit 86be408bfbd8 ("clk: Support for clock parents and rates
assigned from device tree"). Since the preferred or correct clock rate will
be board specific this is probably where it should go.
