* [PATCH v4] libertas: Added callback functions to support SDIO suspend/resume.

In-Reply-To: <5FF020A1CFFEEC49BD1E09530C4FF595056D1B6FCD@SC-VEXCH1.marvell.com>
In suspend() host sleep is activated using already configured
host sleep parameters through wol command, and in resume() host
sleep is cancelled. Earlier priv->fw_ready flag used to reset and
set in suspend and resume handler respectively. Since after suspend
only host goes into sleep state and firmware is always ready, those
changes in flag state are removed.

* [PATCH] cfg80211: make action channel type optional
From: Johannes Berg @ 2010-05-19 10:17 UTC (permalink / raw)
To: John Linville; +Cc: Jouni Malinen, linux-wireless
When sending action frames, we want to verify
that we do that on the correct channel. However,
checking the channel type in addition can get in
the way, since the channel type could change on
the fly during an association, and it's not
useful to have the channel type anyway since it
has no effect on the transmission. Therefore,
make it optional to specify so that if wanted,
it can still be checked, but is not required.

* [PATCH 08/29] pcmcia: dev_node removal (drivers with updated printk call)
From: Dominik Brodowski @ 2010-05-19 6:42 UTC (permalink / raw)
To: linux-pcmcia
Cc: Dominik Brodowski, Harald Welte, linux-ide, linux-wireless,
netdev, linux-usb
In-Reply-To: <20100519064149.GA5755@comet.dominikbrodowski.net>
As a second step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, except one printk() which can
easily be replaced by a dev_info()/dev_warn() call.

* [PATCH 07/29] pcmcia: dev_node removal (write-only drivers)
From: Dominik Brodowski @ 2010-05-19 6:42 UTC (permalink / raw)
To: linux-pcmcia
Cc: Dominik Brodowski, linux-bluetooth, Harald Welte, linux-mtd,
linux-wireless, netdev, linux-serial, alsa-devel
In-Reply-To: <20100519064149.GA5755@comet.dominikbrodowski.net>
dev_node_t was only used to transport some minor/major numbers
from the PCMCIA device drivers to deprecated userspace helpers.
However, only a few drivers made use of it, and the userspace
helpers are deprecated anyways. Therefore, get rid of dev_node_t .
As a first step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, but did not make use of it.

* [PATCH 09/29] pcmcia: dev_node removal (drivers with unregister_netdev check)
From: Dominik Brodowski @ 2010-05-19 6:42 UTC (permalink / raw)
To: linux-pcmcia; +Cc: Dominik Brodowski, netdev, linux-wireless
In-Reply-To: <20100519064149.GA5755@comet.dominikbrodowski.net>
As a third step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, except to determine whether
register_netdev() succeeded previously. However, the function calling
unregister_netdev() was only ever called by the PCMCIA core if
register_netdev() succeeded previously. The lonely exception was
easily fixed.

* [PATCH 05/29] pcmcia: re-work pcmcia_request_irq()
From: Dominik Brodowski @ 2010-05-19 6:42 UTC (permalink / raw)
To: linux-pcmcia
Cc: Dominik Brodowski, linux-bluetooth, netdev, linux-wireless,
linux-serial, alsa-devel, linux-usb, linux-ide
In-Reply-To: <20100519064149.GA5755@comet.dominikbrodowski.net>
Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:
- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
clean up automatically on calls to pcmcia_disable_device() or
device ejection.
- drivers still not capable of IRQF_SHARED (or not telling us so) may
use the deprecated pcmcia_request_exclusive_irq() for the time
being; they might receive a shared IRQ nonetheless.

+ - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

* no cs_error / CS_CHECK / CONFIG_PCMCIA_DEBUG (as of 2.6.33)
Instead of the cs_error() callback or the CS_CHECK() macro, please use

* [PATCH] rt2x00: don't use to_pci_dev in rt2x00pci_uninitialize
From: Helmut Schaa @ 2010-05-19 6:47 UTC (permalink / raw)
To: John Linville; +Cc: Ivo van Doorn, Gertjan van Wingerde, linux-wireless, users
Don't use to_pci_dev in rt2x00pci_uninitialize to get the allocated irq
as it won't work for platform devices (SoC). Instead, use the irq field
that's already used everywhere else.

STA_NOTIFY_ADD and STA_NOTIFY_REMOVE have no users anymore,
and station addition/removal are indicated to drivers
using sta_add() and sta_remove(), which can sleep.

No need to bunch these up together, in fact it would help the review
process if instead you spit these up by series which are relevant to
each other.
The stable fix is one alone, the antenna stuff should be a separate
series, then the other stuff if they are not related as a separate
series.

Unless its a fix, I think its too late.

* [PATCH v2 20/20] ath5k: no need to save/restore the default antenna
From: Bruno Randolf @ 2010-05-19 1:32 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
Since ath5k_hw_set_antenna_mode() always writes the default antenna register
and is called at the end of reset, there is no need to separately save and
restore the default antenna.

* [PATCH v2 19/20] ath5k: new function for setting the antenna switch table
From: Bruno Randolf @ 2010-05-19 1:32 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
Collect all pieces concering the antenna switch table into one function.
Previously it was split up between ath5k_hw_reset() and
ath5k_hw_commit_eeprom_settings().
Also we need to set the antenna switch table when ath5k_hw_set_antenna_mode()
is called manually (by "iw phy0 antenna set", for example).
I'm not sure if we need to set the switchtable at the same place in
ath5k_hw_reset() as it was before - it is set later thru
ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid
problems(?).
Plus print switchtable registers in the debugfs file.

* [PATCH v2 18/20] ath5k: update AR5K_PHY_RESTART_DIV_GC values to match masks

To: linville; +Cc: ath5k-devel, linux-wireless

#define AR5K_PHY_RESTART_DIV_GC 0x001c0000
is 3 bit wide.
The previous values of 0xc and 0x8 are 4bit wide and bigger than the mask.
Writing 0 and 1 to AR5K_PHY_RESTART_DIV_GC is consistent with the comments and
initvals we have in the HAL.

Support setting the antenna configuration via cfg/mac80211. At the moment only
allow the simple pre-defined configurations we already have (fixed antenna A/B
or diversity), but more advanced settings should be possible later.

* [PATCH v2 13/20] cfg80211: Add nl80211 antenna configuration
From: Bruno Randolf @ 2010-05-19 1:31 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
Allow setting TX and RX antenna configuration via nl80211/cfg80211.
The antenna configuration is defined as a bitmap of allowed antennas. This
bitmap is 8 bit at the moment, each bit representing one antenna. If multiple
antennas are selected, the driver may use diversity for receive and transmit.
This allows for a simple, yet flexible configuration interface for antennas,
while drivers may reject configurations they cannot support.

In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
Since we have sysfs to manually set the ANI levels, we should print errors to
the kernel log if the values are out of bounds.

* [PATCH v2 09/20] ath5k: use ath5k_softc as driver data
From: Bruno Randolf @ 2010-05-19 1:31 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
It's our "private driver data"... It's used more often and hw is the mac80211
part. This makes more sense with the next (sysfs) patch.

* [PATCH v2 08/20] ath5k: clarify logic when to enable spur mitigation filter
From: Bruno Randolf @ 2010-05-19 1:31 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In-Reply-To: <20100519012528.22206.77550.stgit@tt-desk>
The old code logically did not make sense and seems to have been confused by
the fact that we could have newer EEPROMs on older hardware. In any case the
spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424.
Spur info is available only from EEPROM versions bigger than 5.3 but but the
EEPOM routines will use static values for older versions, so that should be
o.k.
