Hi, thank you.

I am able to modify the defconfig using menuconfig. But what about the DTS? Which MCASP pins connect to the MAX98091?

Hello,

Please review the MAX98901 datasheet and figure out the important pins related to clocks + data. We do not have a max98091 config by default but here is an example for your reference:

1. McASP config: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am437x-gp-evm.dts?h=ti-linux-5.10.y#n1094
2. McASP pinmux: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am437x-gp-evm.dts?h=ti-linux-5.10.y#n454
3. Codec config (showing aic as an example): https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am437x-gp-evm.dts?h=ti-linux-5.10.y#n712
4. Sound configuration: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am437x-gp-evm.dts?h=ti-linux-5.10.y#n115

The above are the key configurations that you would need to enable in your DT file.

Regards,
Krunal
