The ABx500 GPIO controller used to provide a set of virtual contiguous

The ABx500 GPIO driver is now only used to convert between GPIO and IRQ

pinctrl/abx500: move IRQ handling to ab8500-core
In its current state the gpio-ab8500 driver looks after some GPIO
lines found on the AB8500 MFD chip. It also controls all of its
own IRQ handling for these GPIOs by inventing some virtual IRQs
and handing those out to sub-devices. There has been quite a bit
of controversy over this and it was a contributing factor to the
driver being marked as BROKEN in Mainline.
The reason for adopting this method was due to added complexity
in the hardware. Unusually, each GPIO has two separate IRQs
associated with it, one for a rising and a different one for a
falling interrupt. Using this method complicates matters further
because the GPIO IRQs are actually sandwiched between a bunch
of IRQs which are handled solely by the AB8500 core driver.
The best way for us to take this forward is to get rid of the
virtual IRQs and only hand out the rising IRQ lines. If a
sub-driver wishes to request a falling interrupt, they can do
so by requesting a rising line in the normal way. They just
have to add IRQ_TYPE_EDGE_FALLING or IRQ_TYPE_EDGE_BOTH, if
they require both in the flags. Then if a falling IRQ is
triggered, the AB8500 core driver will know how to handle the
added complexity accordingly. This should greatly simply things.

drivers/pinctrl: grab default handles from device core
This makes the device core auto-grab the pinctrl handle and set
the "default" (PINCTRL_STATE_DEFAULT) state for every device
that is present in the device model right before probe. This will
account for the lion's share of embedded silicon devcies.
A modification of the semantics for pinctrl_get() is also done:
previously if the pinctrl handle for a certain device was already
taken, the pinctrl core would return an error. Now, since the
core may have already default-grabbed the handle and set its
state to "default", if the handle was already taken, this will
be disregarded and the located, previously instanitated handle
will be returned to the caller.
This way all code in drivers explicitly requesting their pinctrl
handlers will still be functional, and drivers that want to
explicitly retrieve and switch their handles can still do that.
But if the desired functionality is just boilerplate of this
type in the probe() function:
struct pinctrl *p;
p = devm_pinctrl_get_select_default(&dev);
if (IS_ERR(p)) {
if (PTR_ERR(p) == -EPROBE_DEFER)
return -EPROBE_DEFER;
dev_warn(&dev, "no pinctrl handle\n");
}
The discussion began with the addition of such boilerplate
to the omap4 keypad driver:
http://marc.info/?l=linux-input&m=135091157719300&w=2
A previous approach using notifiers was discussed:
http://marc.info/?l=linux-kernel&m=135263661110528&w=2
This failed because it could not handle deferred probes.
This patch alone does not solve the entire dilemma faced:
whether code should be distributed into the drivers or
if it should be centralized to e.g. a PM domain. But it
solves the immediate issue of the addition of boilerplate
to a lot of drivers that just want to grab the default
state. As mentioned, they can later explicitly retrieve
the handle and set different states, and this could as
well be done by e.g. PM domains as it is only related
to a certain struct device * pointer.

- Deleted a piece of documentation recommending that pins

- Move kref initialization to pinctrl_create().
- Seeking Tested-by from Stephen Warren so we do not disturb

ChangeLog v2->v3 (Linus):
- Abstain from using IS_ERR_OR_NULL() in the driver core,
Russell recently sent a patch to remove it. Handle the
NULL case explicitly even though it's a bogus case.
- Make sure we handle probe deferral correctly in the device
core file. devm_kfree() the container on error so we don't
waste memory for devices without pinctrl handles.
- Introduce reference counting into the pinctrl core using
<linux/kref.h> so that we don't release pinctrl handles
that have been obtained for two or more places.
ChangeLog v1->v2 (Linus):
- Only store a pointer in the device struct, and only allocate

ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

This was our mistakes so chagnes it correctly. For this,
I'm not sure that this patch should go to -fix or -next.
So please give me any comment if there is any problem.
- consider buffer allocation without iommu
. Without iommu, dma_alloc_attrs function allocates some
memory region and returns cpu address so this patch makes
the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
. to avoid the duplication of same code, use
exynos_drm_crtc_finish_pageflip function commonly instead
of each one.
- fix fimd resume issue.
