Align Raspberry Pi DMA interrupts with Linux DTS
...
There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.
All Raspberry Pi models 1-3 (based on bcm2835) have
Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25):
/* dma channel 11-14 share one irq */
This information is repeated in the driver code
(drivers/dma/bcm2835-dma.c +1344):
/*
* in case of channel >= 11
* use the 11th interrupt and that is shared
*/
In this patch channels 0--10 and 11--14 are handled separately.
