Use platform_get_irq_byname to allow for correct mapping of
interrupts to dma channels.
The currently implemented device tree is unfortunately
implemented with the wrong assumption, that each dma-channel
has its own dma channel, but dma-irq 11 is handling
dma-channel 11-14 and dma-irq 12 is actually a "catch all"
interrupt.
So here we use the byname variant and require that interrupts
are explicitly named via the interrupts-name property in the
interrupt-names
Vinod has just merged this patch - do you want me to submit another
to correct those?
You're not explicitly looking for "dma-shared-all" for that?
You might as well just declare a single unnamed interrupt in the bindings.
dma-shared-all is unfortunately an interrupt-line that triggers
for interrupt-channels 0-15 and that includes the dma channels
that are owned by the firmware.
It is there mostly to document the interrupt-line (which is there in the
existing device tree files - it is not used.
