SGTL5000 Family CODEC - Rpi5 Linux compatibility

[laxamar]

We are trying to choose an Audio CODEC for a Raspberry Pi5 using I2S and I2C and have found SGTL5000XNBA3R2 as a possible solution. However, there is no desire to create a driver and we'd like to have Linux support the chip natively (ubuntu 24.04) 

Do we know if this is supported by Linux natively?

===

Additionally a functioning reference schematic would be appreciated that is more detailed that the datasheet

Thanks

Thanks!
Driver is built-in.
Would you be able to point me to an device tree overlay necessary to make it work on a raspberry pi5?

Hi
 

There is no such demo dts for RPI5, you can refer other dts which use SGTL5000 in kernel.
