From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anson.Huang@freescale.com (Anson Huang) Date: Tue, 20 Oct 2015 18:44:19 +0800 Subject: [PATCH V2] ARM: imx: add platform irq type setting in gpc Message-ID: <1445337859-19111-1-git-send-email-Anson.Huang@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Anson Huang GPC irq domain is a child domain of GIC, now all of platform irqs are inside GPC domain, during the module populate, all devices irq should have correct type setting in GIC, however, there is no .irq_set_type callback setting in GPC, so the irq_set_type will be skipped and cause all irqs' type in /proc/interrupt are "edge" which mismatch with irq type setting in dtb file. Since GPC has no irq type setting, so just tell kernel to use irq_chip_set_type_parent.
