[PATCH 1/3] dt/bindings: bcm2835: add interrupt-names property

[kernel-TqfNSX0MhmxHKSADF0wUEw@public.gmane.org]

From: Martin Sperl <kernel-TqfNSX0MhmxHKSADF0wUEw@public.gmane.org>

Added standard interrupt-names property so that
platform_get_irq_byname() can get used to fetch the
interrupt corresponding to each dma_channel
instead of the current platform_get_irq() with
an assumed ordering of the interrupts.

Signed-off-by: Martin Sperl <kernel-TqfNSX0MhmxHKSADF0wUEw@public.gmane.org>

 DMA clients connected to the BCM2835 DMA controller must use the format
 described in the dma.txt file, using a two-cell specifier for each channel.
