2021-10-26irq: remove handle_domain_{irq,nmi}()Mark Rutland1-1/+1
Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

2016-06-21ARM: i.MX: Fix FIQ interrupt handling for TZICAlexander Shiyan1-3/+3

2016-02-02ARM: imx: use endian-safe readl/readw/writel/writewJohannes Berg1-17/+17
Instead of __raw_*, define imx_* to *_relaxed and use those. Using imx_* was requested by Arnd because *_relaxed tends to indicate that the code was carefully reviewed to not require any synchronisation and otherwise be safe, which isn't the case here with the automatic conversion. The conversion itself was done using the following spatch (since that automatically adjusts the coding style unlike a simple search&replace). @@ expression E1, E2; @@ -__raw_writel(E1, E2) +imx_writel(E1, E2) @@ expression E1, E2; @@ -__raw_writew(E1, E2) +imx_writew(E1, E2) @@ expression E1; @@ -__raw_readl(E1) +imx_readl(E1) @@ expression E1; @@ -__raw_readw(E1) +imx_readw(E1) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2012-10-15ARM: imx: remove header file mach/irqs.hShawn Guo1-2/+0
The only mach/irqs.h user outside arch/arm/mach-imx is sound/soc/fsl/imx-pcm-fiq.c, which refers to mxc_set_irq_fiq(). Move the declaration into include/linux/platform_data/asoc-imx-ssi.h, so that we can remove mach/irqs.h includsion from imx-pcm-fiq.c. Inside arch/arm/mach-imx, the only users to mach/irqs.h are avic.c and tzic.c for referring to macro FIQ_START. Let's move the macro into irq-common.h and get rid of mach/irqs.h completely.

2012-10-15ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo1-1/+1
It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h.

2012-10-15ARM: imx: merge plat-mxc into mach-imxShawn Guo1-0/+224
It's really unnecessary to have plat-mxc, and let's merge it into mach-imx. It's pretty much just a bunch of file renaming and Kconfig/Makefile merge. To make the change less invasive, we keep using Kconfig symbol CONFIG_ARCH_MXC for mach-imx sub-architecture.
