On a MMP2, the DMA interrupt is shared by all channels of the peripheral DMA controller and the audio DMA controller. Both drivers can identify their interrupts, but only the PDMA driver marks the line shared: [ 1.185782] mmp-pdma d4000000.dma: initialized 16 channels [ 1.186808] mmp-tdma d42a0800.adma: IRQ index 1 not found [ 1.194317] genirq: Flags mismatch irq 64. 00000000 (tdma) vs. 00000080 (pdma) [ 1.197894] mmp-tdma: probe of d42a0800.adma failed with error -16 Let's turn on IRQF_SHARED in the ADMA driver as well.
