While the comment removed in this patch claims board_n800.c uses
"cx3110x", it was never merged to mainline like this. Mainlined board
files for Nokia N8x0 devices are expected "p54spi", and thus don't
work because the modalias is "cx3110x". To my knowledge, these
devices are the only real-world use of p54spi, and will not work
without this change. Tested against my Nokia N810.

In kernel Bugzilla #15825 (2 users), in a wireless mailing list thread
(http://lists.infradead.org/pipermail/b43-dev/2010-May/000124.html), and on a
netbook owned by John Linville
(http://marc.info/?l=linux-wireless&m=127230751408818&w=4), there are reports
of ssb failing to detect an SPROM at the normal location. After studying the
MMIO trace dump for the Broadcom wl driver, it was determined that the affected
boxes had a relocated SPROM.
This patch fixes all systems that have reported this problem.

If buffer is to be accessed by cpu after dma is over, but
between dma mapping and dma unmapping, we should use
dma_sync_single_for_cpu to sync the buffer between cpu with
device. And dma_sync_single_for_device is used to let
device gain the buffer again.
v2: Felix pointed out dma_sync_single_for_device is needed to return
buffer to device if an unsuccessful status bit check is found.

Because there is a limited number of tx buffers available, once the
queue has been filled to a certain point, ath9k needs to stop accepting
new frames from mac80211. In order to prevent a full WMM queue from
stopping another queue with fewer frames, this patch limits the number
of queued frames to a quarter of the total available tx buffers, minus
some reserved frames to be used for other purposes (e.g. beacons).
Because tx buffers are reserved for frames when they're staged in
software queues as well, the actual queue depth cannot be used for
this, so this patch stores a reference to the tx queue in the ath_buf
struct and keeps track of the total number of pending frames.

This patch revamps IDLE power save handling in the driver.
Two separate functions (radio enable/disable) are introduced,
because the semantics of radio handling is just not the same
as the start()/stop() callbacks. For example, the HW must not
be disabled, instead, the PHY has to be disabled in radio_disable().
Also, the HW has to be reset properly in radio enable/disable and
certain registers have to be programmed only once, in the
start() callback.
The radio_enable() routine doesn't need the PS wrappers since
we set the HW power mode to AWAKE anyway before calling it.

Rather than doing a series of RMWs, calculate the
value to be written to the register in question and
do a single REGWRITE. This improves bringup time.
This depends on the analog_shiftreg configuration option,
which is currently buggy. For AP mode, a delay of 100us
has to be the default. For station mode, this knob has to
be enabled on a per-case basis, though it is a little
unclear on when to enable a delay. This can be fixed later though.

There's no sense in letting anything but internal
mac80211 functions set the initiator to anything
but WLAN_BACK_INITIATOR, since WLAN_BACK_RECIPIENT
is only valid when we have received a frame from
the peer, which we react to directly in mac80211.
The debugfs code I recently added got this wrong
as well.

For rt2800 reverse the calling order of rt2x00pci_write_data and
rt2800pci_write_data. Currently rt2800pci_write_data calls rt2x00pci_write_data
as there can be only 1 driver callback function specified by the driver.
Reverse this calling order by introducing a new driver callback function,
called write_tx_datadesc, which is called from the bus-specific write_tx_data
functions.
