This patch moves all mac pib attributes into the wpan_dev struct.
Furthermore we can easier access these attributes over the netdev
802154_ptr pointer. Currently this is only possible over a complicated
callback structure in mac802154 because subif data structure is
accessable inside mac802154 only.

Currently the composite quirk doesn't work when multiple entries are
assigned to the same interface because it marks the interface as
claimed then checks whether the interface has been already claimed for
the secondary entry. But, if you look at the code, you'll notice that
multiple entries are allowed if the entry is the current interface;
i.e. the current behavior is anyway inconsistent, and this is an
unintended shortcoming.
This patch fixes the problem by marking the relevant interfaces as
claimed after applying the all composite entries. This fix will be
needed for the upcoming enhancements for Digidesign Mbox 1 quirks.

The function exynos_irq_demux_eint16_31 uses pre-defined offsets for external
interrupt pending status and mask registers. So this function is not extensible
for Exynos7 SoC which has these registers at different offsets. Generalize
the exynos_irq_demux_eint16_31 function by using the pending/mask register
offset values from the exynos_irq_chip structure. This is done by adding a

This patch intends to solve this by introducing a new

5th and 6th byte of ALPS trackstick V3 protocol match condition for first
byte of PS/2 3 bytes packet. When driver enters out of sync state and ALPS
trackstick is sending data then driver match 5th, 6th and next 1st bytes as
PS/2.
It basically means if user is using trackstick when driver is in out of
sync state driver will never resync. Processing these bytes as 3 bytes PS/2
data cause total mess (random cursor movements, random clicks) and make
trackstick unusable until psmouse driver decide to do full device reset.
Lot of users reported problems with ALPS devices on Dell Latitude E6440,
E6540 and E7440 laptops. ALPS device or Dell EC for unknown reason send
some invalid ALPS PS/2 bytes which cause driver out of sync. It looks like
that i8042 and psmouse/alps driver always receive group of 6 bytes packets
so there are no missing bytes and no bytes were inserted between valid
ones.
This patch does not fix root of problem with ALPS devices found in Dell
Latitude laptops but it does not allow to process some (invalid)
subsequence of 6 bytes ALPS packets as 3 bytes PS/2 when driver is out of
sync.
So with this patch trackstick input device does not report bogus data when
also driver is out of sync, so trackstick should be usable on those
machines.

This effectively converts the __raw_ accessors to the non-__raw_
equivalents. To handle BE, we pass IRQ_GC_BE_IO, similar to what was
done in irq-bcm7120-l2.c.
Since irq_reg_writel now takes an irq_chip_generic argument, writel must
be used for the initial hardware reset in the probe function. But that
operation never needs endian swapping, so it's probably not a big deal.

On BE MIPS systems this needs to use the new IRQ_GC_BE_IO gc_flag. In
all other cases it will use the standard readl/writel accessors.
The initial irq_fwd_mask setup runs before "gc" is initialized, so it
is unchanged for now. This could potentially be a problem on an ARM
system that boots in LE mode but runs a BE kernel, but currently none
of the supported ARM platforms are ever expected to run BE.

Most implementations of the bcm7120-l2 controller only have a single
32-bit enable word + 32-bit status word. But some instances have added
more enable/status pairs in order to support 64+ IRQs (which are all
ORed into one parent IRQ input). Make the following changes to allow
the driver to support this:
- Extend DT bindings so that multiple words can be specified for the
reg property, various masks, etc.
- Add loops to the probe/handle functions to deal with each word
separately
- Allocate 1 generic-chip for every 32 IRQs, so we can still use the
clr/set helper functions
- Update the documentation
This uses one domain per bcm7120-l2 DT node. If the DT node defines
multiple enable/status pairs (i.e. >=64 IRQs) then the driver will
create a single IRQ domain with 2+ generic chips. Multiple generic chips
are required because the generic-chip code can only handle one
enable/status register pair per instance.

This check may be prone to race conditions, e.g.
1) Some external event (e.g. GPIO level) causes an IRQ to become pending
2) Peripheral asserts the L2 IRQ
3) CPU takes an interrupt
4) The event from #1 goes away
5) bcm7120_l2_intc_irq_handle() reads back a 0 status
Unlike the hardware supported by brcmstb-l2, the bcm7120-l2 controller
does not latch the IRQ status. Bits can change if the inputs to the
controller change. Also, do_bad_IRQ() is an ARM-specific macro.
So let's just nuke it.
