commit bc8966 (ARM: fiq: change FIQ_START to a variable) introduced the following build error for imx_v4_v5_defconfig: arch/arm/plat-mxc/avic.c:220:11: error: 'FIQ_START' undeclared (first use in this function) Include the missing header file to fix it.

2012-07-01ARM: fiq: change FIQ_START to a variableShawn Guo1-1/+1
The commit a2be01b (ARM: only include mach/irqs.h for !SPARSE_IRQ) makes mach/irqs.h only be included for !SPARSE_IRQ build. There are a nubmer of platforms have FIQ_START defined in mach/irqs.h for FIQ support. arch/arm/mach-rpc/include/mach/irqs.h:#define FIQ_START 64 arch/arm/mach-s3c24xx/include/mach/irqs.h:#define FIQ_START IRQ_EINT0 arch/arm/plat-mxc/include/mach/irqs.h:#define FIQ_START 0 If SPARSE_IRQ is enabled for any of these platforms, the following compile error will be seen. arch/arm/kernel/fiq.c: In function ‘enable_fiq’: arch/arm/kernel/fiq.c:127:19: error: ‘FIQ_START’ undeclared (first use in this function) arch/arm/kernel/fiq.c:127:19: note: each undeclared identifier is reported only once for each function it appears in arch/arm/kernel/fiq.c: In function ‘disable_fiq’: arch/arm/kernel/fiq.c:132:20: error: ‘FIQ_START’ undeclared (first use in this function) The patch changes fiq code to have init_FIQ take FIQ_START from platforms as a parameter and assign it to variable fiq_start which is to replace FIQ_START uses in enable_fiq/disable_fiq.

2012-07-01ARM: imx: move irq_domain_add_legacy call into avic driverShawn Guo1-7/+25
Move irq_domain_add_legacy call from imx27-dt.c into avic init function and have the avic driver adopt irqdomain support for both DT and non-DT boot. Now avic init function calls irq_alloc_descs to get irq_base and adds a lenacy irqdomain with the irq_base, so that the mapping between avic irq and Linux irq number can be handled by irqdomain.

2011-09-23ARM i.MX avic: convert to use generic irq chipHui Wang1-23/+56
Convert i.MX avic irq handler to use generic irq chip. This not only provides a cleanup implementation of irq chip handler, but also implements suspend/resume interface with the help of generic irq chip interface. Change mxc_irq_chip to a new structure mxc_extra_irq to handle fiq and priority functions.

2010-11-24ARM i.MX irq: Compile avic irq code only on SoCs that need itSascha Hauer1-0/+152
This patch adds a Kconfig option for the avic irq controller and lets the SoCs that need it select this option. Also, as we have two irq controllers for i.MX, irq.c is not appropriate anymore, so rename it to avic.c Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
