The core code provides the same functionality when the
IRQCHIP_EOI_IF_HANDLED flag is set for the irq chip.Signed-off-by: Thomas Gleixner
-
The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus.The new core code allows to update the type in irq_data and return
IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for
setting the IRQ_LEVEL flag.Use the proper accessors for setting the irq handlers.

Port C interrupts can be either falling edge, or either edge.
Other external interrupts are either falling edge or active low.

Writing a driver using SCLPC on the MPC5200B I detected, that the
intspec arrays to map irqs to Linux virq cannot be const, because the
mapping and xlate functions only take non const pointers. All those
functions do not modify the intspec, so a const pointer could be used.Signed-off-by: Roman Fietze

get_irq_desc() is a powerpc-specific version of irq_to_desc(). That
is reason enough to remove it, but it also doesn't know about sparse
irq_desc support which irq_to_desc() does (when we enable it).Signed-off-by: Michael Ellerman

This is a simple change to correct problems when using set_irq_type
on platforms using CPM2. This code corrects the problem on most platform
but may have issues on 8272 derived platforms for some interrupts.On 8272 PC2 & 3 are missing and PC 23 & 29 are added, which this patch
does not address.Signed-off-by: Paul Bilke

When I changed irq_alloc_host() to take an of_node
(52964f87c64e6c6ea671b5bf3030fb1494090a48: "Add an optional
device_node pointer to the irq_host"), I botched the reference
counting semantics.Stephen pointed out that it's irq_alloc_host()'s business if
it needs to take an additional reference to the device_node,
the caller shouldn't need to care.Signed-off-by: Michael Ellerman

The most common match semantic is an exact match based on the device node.
So provide a default implementation that does this, and hook it up if no

The majority of irq_host implementations (3 out of 4) are associated
with a device_node, and need to stash it somewhere. Rather than having
it somewhere different for each host, add an optional device_node pointer
to the irq_host structure.Signed-off-by: Michael Ellerman

This contains important fixes for the CPM2 PIC code. Eliminated
CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt
mapping. Updated devicetree files to reflect that. Changed direct
IC-related IO accesses to the IO accessors. Fixed all the sense values to
keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs
and hence could be hardly usable.Signed-off-by: Vitaly Bordug

It's ok to remove 'node' check because in real life cpm2_pic_init()

The stuff below cleans up the code attempting to remap the whole cpm2_immr
early, as well as places happily assuming that fact. This is more like the 2.4
legacy stuff, and is at least confusing and unclear now.To keep the world comfortable, a new mechanism is introduced: before accessing
specific immr register/register set, one needs to map it, using cpm2_map(),
for instance, access to CPM command register will look like
volatile cpm_cpm2_t *cp = cpm2_map(im_cpm);
keeping the code clear, yet without "already defined somewhere" cpm2_immr.So far, unmapping code is not implemented, but it's not a big deal to add it,
if the whole idea makes sense.Signed-off-by: Vitaly Bordug
