X-Git-Tag: v3.0~2001^2~26
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=63b549b6552c7869c25a1c60783aa86a3380e06c;p=platform%2Fkernel%2Flinux-amlogic.git

m32r: Convert m32700ut pld irq chip

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.
