Subject: sh: multiple vectors per irq - sh7760
X-Git-Tag: firefly_0821_release~13982^2~41^2~30
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3d6ad460214cc72b93333f51f498441a56d622e9;p=firefly-linux-kernel-4.4.55.git

sh: multiple vectors per irq - sh7760

Update intc tables and platform data to use one linux irq
per maskable interrupt source instead of keeping the one-to-one
mapping between vectors and linux irqs.

This fixes potential irq masking issues for sh7760 hardware
blocks such as DMAC/TMU2/REF.
