Subject: [PATCH V2 1/3] dt/bindings: bcm2835: add interrupt-names property
Date: Mon, 11 Apr 2016 13:29:07 +0000	[thread overview]
Message-ID: <1460381349-14408-2-git-send-email-kernel@martin.sperl.org> (raw)
In-Reply-To: <1460381349-14408-1-git-send-email-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.
