Subject: [RFC PATCH 0/2] Remove at91 workaround from handle_IRQ
Date: Thu, 31 May 2012 08:38:19 +0100	[thread overview]
Message-ID: <1338449901-10288-1-git-send-email-will.deacon@arm.com> (raw)

Hello,

This is a couple of patches that I wrote quickly to try and remove the
irq_finish hook from handle_IRQ on ARM. Currently, the hook is only used
by at91 in order to issue an EOI when using level_irq flow control.

This patch moves the at91 irq_chip to fasteoi flow control, removing the
need for the additional hook. Since I (a) don't know anything about at91
(the TRM I found for the IRQ controller is only a few pages long) and (b)
don't have a platform on which to test, this is very much an RFC series.

All comments welcome.

Will
