Hi Krzysztof,

Thanks for your review, and please see my responses inline.

You are right — the error paths miss the corresponding
clk_disable_unprepare() cleanup. I will update the probe logic to ensure
the clock is properly disabled along all failure paths

Thanks for pointing this out. To ensure proper cleanup in both the probe
error path and a potential future remove() implementation, I will switch to
devm_dma_request_chan(), so that DMA channels are automatically released
by the device core.

Understood. I will fix the compatible strings and ensure all of them are
properly documented in the binding.

Thanks again for your review and suggestions.

Best regards,
CL
