From mboxrd@z Thu Jan 1 00:00:00 1970 From: will.deacon@arm.com (Will Deacon) Date: Thu, 31 May 2012 08:38:19 +0100 Subject: [RFC PATCH 0/2] Remove at91 workaround from handle_IRQ Message-ID: <1338449901-10288-1-git-send-email-will.deacon@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
