The driver calls dma_set_coherent_mask() but never dma_set_mask(), leaving the streaming DMA mask at the bus default. On the non-coherent EN7581 platform (Cortex-A53), this causes the NPU mailbox to hang after approximately 41 calls when using streaming DMA mappings.
Can you confirm if patch 2 is still needed after this fix?
