This reverts commit 393fb560.

Commit b6ad726e ("mmc: core: Prevent too long response times
for suspend") fails the suspend if the mmc host can't be
claimed before suspend. As the host is claimed by us as long
as the chip is powered on, suspend will always fail.

Revert to claiming the sdio bus only when needed.

wl1271_tx_update_filters() is used as some workaround
to open filters while roaming on the same channel.

However, it doesn't handle roaming to a different channel,
and it might also sleep in the tx path, which is a bug.

With the new auth/assoc redesign, roaming is much simpler,
and this function is not needed anymore.

Add a testmode command to retrieve the BD_ADDR that is stored in the
Fuse ROM in newer PGs.  In old PGs this operation is not supported.
The caller can then derive the MAC addresses from it.
Signed-off-by: Luciano Coelho <coelho@ti.com>

Add support for two MAC addresses.  If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.

If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM.  If it does, we read it and derive
the two subsequent addresses for WLAN.

During production, 3 addresses are reserved per device.  The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

This patch has some code by Igal and Arik (squashed from internal
patches).

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version.  We need to know the MAC address
during probe, because that's when we register our HW with mac80211.

To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time.  We power the chip on
briefly in order to do that.

Up till now we only needed to access the partition table in boot.c.
But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.

Thus, we move the partition table to io.c and export it via io.h.  It
makes more sense to have it in the io part anyway.

The interrupt threaded handler exits immediately if the driver's state
is WL1271_STATE_OFF. As a result, the interrupt status is not read. If
the interrupt is level triggered, it will be fired again.

When stopping plt, the chip is powered off before all current work items
are flushed and interrupts are disabled. This might introduce a race in
which the driver tries to communicate with a powered off chip.

If you want to use mesh support from mac80211 on a recent
kernel on 2.6.24 you'll run into a name clash when compiling
against include/linux/namei.h, so rename this routine.

/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c: At top level:
/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c:342:26: error: conflicting types for ‘path_lookup’
include/linux/namei.h:71:12: note: previous declaration of ‘path_lookup’ was here

Although this could sit as a separate patch in compat-wireless it seems
best to just merge upstream.
