From: Nishanth Menon Date: Thu, 26 Jun 2014 07:10:33 +0000 (+0530) Subject: documentation: dt: omap: crossbar: Add description for interrupt consumer X-Git-Tag: v3.17-rc1~110^2~5^2^2~1 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a34f73fb75531507760b957407fb55278b38ae8;p=karo-tx-linux.git documentation: dt: omap: crossbar: Add description for interrupt consumer The current crossbar description does not include the description required for the consumer of the crossbar, a.k.a devices whoes events pass through the crossbar into the GIC interrupt controller. So, provide documentation for the same.
