From mboxrd@z Thu Jan 1 00:00:00 1970 From: khilman@ti.com (Kevin Hilman) Date: Fri, 22 Apr 2011 16:01:54 -0700 Subject: [PATCH 02/15] OMAP: GPIO: remove MPUIO handling from _clear_gpio_irqbank() In-Reply-To: <1303513327-14532-1-git-send-email-khilman@ti.com> References: <1303513327-14532-1-git-send-email-khilman@ti.com> Message-ID: <1303513327-14532-3-git-send-email-khilman@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Remove the OMAP1 #ifdef and MPUIO special case for _clear_gpio_irqbank() The MPUIOs do not need a register access to ack/clear the IRQ status, since reading the IRQ status clears it. In addition, the MPUIO irq_chip has an empty ack method, so _clear_gpio_irqbank() is never used for MPUIOs.
