From mboxrd@z Thu Jan 1 00:00:00 1970 From: lee.jones@linaro.org (Lee Jones) Date: Thu, 9 Aug 2012 16:53:53 +0100 Subject: [PATCH 6/8] mfd: Use interrupt-parent as IRQ controller if specified in DT In-Reply-To: <1344527635-6163-1-git-send-email-lee.jones@linaro.org> References: <1344527635-6163-1-git-send-email-lee.jones@linaro.org> Message-ID: <1344527635-6163-7-git-send-email-lee.jones@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Without this patch the default behaviour is to climb the Device Tree and use the first encountered interrupt controller. This does not take into account if a device node has specified to use a particular IRQ controller using the interrupt-parent property. This patch ensures that property is adhered to.
