This reverts commit bda7c4c2b9767ce2af4394754498662d62079af5.
These drivers build as modules now that we use
platform_irq_count() instead of of_irq_count().

of_irq_count() is not an exported symbol (and it shouldn't be
used by platform drivers anyway) so use platform_irq_count()
instead. This allows us to make the qcom pinctrl drivers modular
again.

A recent patch added calls to of_irq_count() in the qcom pinctrl
drivers and that caused module build failures because
of_irq_count() is not an exported symbol. We shouldn't export
of_irq_count() to modules because it's an internal OF API that
shouldn't be used by drivers. Platform drivers should use
platform device APIs instead. Therefore, add a platform_irq_count()
API that mirrors the of_irq_count() API so that platform drivers
can stay DT agnostic.

The driver calls pci_set_mwi to enable memory-write-invalidate when it
is initialized, but does not call pci_clear_mwi when it is removed. Many
other drivers calls pci_clear_mwi when pci_set_mwi is called, such as
r8169, 8139cp and e1000.
This patch adds pci_clear_mwi in error handling and removal procedure,
which can fix the problem.

When the driver is being unloaded a situation can occur where the
wirelesss core (cfg80211) wants to remove the ibss, but the state
of brcmfmac has already been set to down. When an error is
returned in that situation then that will result in a stack
trace on removal of the wiphy object. This is avoided by
returning 0 when device is down on a leave_ibss call.

|

batadv_iv_ogm_orig_del_if removes a part of the bcast_own which previously
belonged to the now removed interface. This is done by copying all data
which comes before the removed interface and then appending all the data
which comes after the removed interface.
The address calculation for the position of the data which comes after the
removed interface assumed that the bat_iv.bcast_own is a pointer to a
single byte datatype. But it is a pointer to unsigned long and thus the
calculated position was wrong off factor sizeof(unsigned long).

Commit 0976c946a610d06e907335b7a3afa6db046f8e1b
"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.
However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.
Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.
For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.
Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.

- Enable the I2C driver
- Enable the SPI driver
- Enable the RTC driver for DS1338 as found on the Versatile
boards
- Compile in the MMCI MMC driver, which is good if you
want to mount a root FS on the MMC card without having
to first load this module from an initramfs

The Nomadik has sporadic crashes because of these latencies, setting
them to max makes the platform work nicely, so use this values for
now.
These latencies were set to 2 since the Nomadik platform was merged,
but I suspect they never took effect until the right size and
associativity for the cache was specified in the device tree and
that is why the crash comes now.

Pull MTD fixes from Brian Norris:
"Three last MTD fixes for v4.4. These are all fixes for regressions
and bugs reported mid cycle. Unfortunately, some of them took a bit
long to get proper testing and feedback.
- Assign the default MTD name earlier in the registration process, so
partition parsers (like cmdlinepart) see the right name. Without
this, some systems may come up with unpartitioned flash. This was
a v4.4-rc1 regression.
- Revert some new Winbond SPI NOR flash unlocking/locking support;
new code in v4.4 caused regressions on some Spansion flash.
- Fix mis-typed parameter ordering in SPI NOR unlock function; this

Add I/O register mapping for DTC chips and enable PDMA mode.
These chips have 16-bit wide HOST BUFFER register and it must be read

Large PIO transfers crash at least the DTCT-436P chip (all reads result

The chip also crashes when we bang on the C400 host status register too
heavily after PDMA write - a small udelay is needed.
