X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=123f5f188638bfc673aca22ade64b863ec3a2804;p=openwrt%2Fstaging%2Fblogic.git

fb: pvr2fb: Shared IRQ for dreamcast pvr2.

The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware
synchronisation between the maple bus and the VBLANK to poll the maple
bus. This patch makes the interrupt shareable.

By definition the interrupt is for both devices.
