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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
