Tool/software:
Hi,
I am currently working on the audio driver bring-up activity for the TDA4VH-Q1 EVM board. While configuring the audio driver, I encountered the following probe errors (Yocto):
[ 13.051645] platform 6000000.usb: deferred probe pending
[ 13.056957] platform sound0: deferred probe pending
[ 13.061832] platform sound1: deferred probe pending
[ 13.066703] platform sound3: deferred probe pending
In additionally, the following clock related errors in the logs:
root@j784s4-evm:~# dmesg | grep -i "clk\|audio"
[ 0.229474] ti-sci-clk 44083000.system-controller:clock-controller: get-parent failed for dev=157, clk=34, ret=-19

below is relevant device tree configuration:

compatible = "simple-audio-card";
simple-audio-card,name = "J784S4-TEST";
simple-audio-card,format = "i2s";

};
could you please assist in identifying and resolving the issue to make the audio driver work correctly?
