Subject: gpio-rcar: R-Car GPIO IRQ share interrupt
X-Git-Tag: next-20130527~8^2^19~2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f2886f860ea62c53d4b2056b290c93450ac8a44d;p=karo-tx-linux.git

gpio-rcar: R-Car GPIO IRQ share interrupt

R-Car H1 or Gen2 GPIO interrupts are assigned per each GPIO domain,
but, Gen1 E1/M1 GPIO interrupts are shared for all GPIO domain.
gpio-rcar driver needs IRQF_SHARED flags for these.
This patch was tested on Bock-W board
