genirq: Add and use an irq_data_update_affinity helper

2022-07-07T08:38:04+00:00

Some architectures and irqchip drivers modify the cpumask returned by irq_data_get_affinity_mask, usually by copying in to it. This is problematic for uniprocessor configurations, where the affinity mask should be constant, as it is known at compile time. Add and use a setter for the affinity mask, following the pattern of irq_data_update_effective_affinity. This allows the getter function to return a const cpumask pointer.

sh/irq: Use access helper irq_data_get_affinity_mask()

2015-07-29T08:08:08+00:00

This is a preparatory patch for moving irq_data struct members. Signed-off-by: Jiang Liu Cc: Simon Horman Cc: Magnus Damm Link: http://lkml.kernel.org/r/20150713151626.713278346@linutronix.de Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

sh: Fix up more fallout from pointless ARM __iomem churn.

2012-10-15T05:08:48+00:00

It was already pointed out how to fix these cases before the offending patches were merged, but unsurprisingly, that didn't happen. As this change is entirely superfluous to begin with, simply shut things up by casting everything away. Signed-off-by: Paul Mundt

sh: intc: optimize intc IRQ lookup

2012-01-24T08:41:55+00:00

This ensures that the sense/prio lists are sorted at registration time, enabling us to use a simple binary search for an optimized lookup (something that had been on the TODO for some time). Signed-off-by: Paul Mundt

sh: intc: Use IRQ_SET_MASK_OK_NOCOPY for intc_set_affinity.

2012-01-24T07:55:57+00:00

intc_set_affinity() updates the cpumask in place, so there's no need for the upper layer to do this itself. Signed-off-by: Paul Mundt

sh: intc: Kill off superfluous irq_shutdown hooking.

2012-01-24T06:38:57+00:00

This already gets handled via disable, as per the notes in linux/irq.h. Signed-off-by: Paul Mundt

sh: intc: Prefer IRQCHIP_SKIP_SET_WAKE over a dummy set_wake callback.

2012-01-24T05:54:10+00:00

It's possible to use IRQCHIP_SKIP_SET_WAKE to get the behaviour that we're after, without having to bother with a dummy ->set_wake() callback for the IRQ chip. Signed-off-by: Paul Mundt

sh: intc: Allow triggering on both edges for ARM SoCs

2011-11-04T15:57:48+00:00

Enable IRQ_TYPE_EDGE_BOTH on all R/SH-Mobile ARM SoCs. This hardware feature is supported by sh7367, sh7377, sh7372 and sh73a0. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: intc: Add IRQ trigger bit field check

2011-10-28T05:39:24+00:00

R-Mobile SoCs such as sh73a0 include PINT blocks in INTC that come with 2-bit IRQ trigger support. Add code to make sure the bit width is checked so 4-bit only modes like for instance EDGE_BOTH will fail for PINT. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: intc: enable both edges GPIO interrupts on sh7372

2011-07-21T07:53:24+00:00

IRQ-capable GPIOs on sh7372 can be configured to produce interrupts on both edges. Signed-off-by: Guennadi Liakhovetski Acked-by: Magnus Damm Signed-off-by: Paul Mundt
