Originally, the reason is to keep __mwifiex_pcie_suspend() and
__mwifiex_pcie_resume() parameters the same so there will be no
confusion. However, I didn't think about using
mwifiex_pcie_resume(&pdev->dev) as you mentioned below. Yes, I can make
the change and not add two additional routines and send a v2 patch.

Yes. That would eliminate the need for additional routine. I didn't
think about that option.

So the reason for this is SIMPLE_DEV_PM_OPS() is defined only when
CONFIG_PM_SLEEP is enabled. This driver doesn't defines suspend and
resume when CONFIG_PM is enabled and I didn't want to change that. Hope
that helps understand why I didn't use SIMPLE_DEV_PM_OPS()

You could use mwifiex_pcie_resume(&pdev->dev) here and then the extra

I think you're right about this. Specifically because the standard limit
is much lower than what is being used now, we need to really make sure
that it's applied in a way that it does not harm the normal use case in
any visible way.

OK, I'll have a look at that part now.

This leads to a question about regressions and backward compatibility:
Since minstrel can compute as much as 28 retries for a frame,
And since the (standard) default value for "short_frame_max_tx_count" is 7,
... there is no way I can enforce the configured value while keeping
minstrel counts by default !
The standard itself gives a very aggressive limit! Or am I mistaken about
the significance of this configuration parameter ?

good to see this happening, I remember we talked about this a while back
:-)

Still, if you call irq_set_irq_type() on board-file (since DT will do
something similar for you anyway) then you can completely drop
irq_flags.

couldn't you just call irq_set_irq_type() from the board-file itself ?
Then on your driver you can just pass IRQF_ONESHOT (to make sure heh) to
your request_threaded_irq_handler()

* [PATCH] wireless: Convert mwifiex/pcie to dev_pm_ops from legacy pm ops
From: Shuah Khan @ 2013-07-02 15:24 UTC (permalink / raw)
To: bzhao, linville, rjw
Cc: Shuah Khan, linux-wireless, netdev, linux-kernel, shuahkhan
Convert the mwifiex/pci driver to use dev_pm_ops for power management and
remove Legacy PM handling. This change re-uses existing suspend and resume
interfaces for dev_pm_ops.

* [PATCH v2 9/9] wlcore/wl12xx: check if we got correct clock data from DT

The fref and the tcxo clocks settings are optional in some platforms.
WiLink8 doesn't need either, so we don't check the values. WiLink 6
only needs the fref clock, so we check that it is valid or return with
an error. WiLink7 needs both clocks, if either is not available we
return with an error.

* [PATCH v2 7/9] wlcore: sdio: add wilink clock providers
From: Luciano Coelho @ 2013-07-02 14:55 UTC (permalink / raw)
To: linux-wireless, tony, nsekhar
Cc: mturquette, mark.rutland, balbi, grant.likely, rob.herring,

In-Reply-To: <1372776948-24840-1-git-send-email-coelho@ti.com>
Add refclock and tcxoclock as clock providers in WiLink. These clocks
are not accesible outside the WiLink module, but they are registered
in the clock framework anyway. Only the WiLink chip consumes these
clocks.
In theory, the WiLink chip could be connected to external clocks
instead of using these internal clocks, so make the clock consumer
code generic enough. If external clocks are used, then the internal
clock device tree nodes are not necessary, but the external ones must
be specified.

If platform data is not available, try to get the required information
from the device tree. Register an OF match table and parse the
appropriate device tree nodes.
Parse interrupt property only, for now.

Instead of defining an enumeration with the FW specific values for the
different clock rates, use the actual frequency instead. Also add a
boolean to specify whether the clock is XTAL or not.
Change all board files to reflect this.

* [PATCH v2 2/9] wlcore: use irq_flags in pdata instead of hiding it behind a quirk
From: Luciano Coelho @ 2013-07-02 14:55 UTC (permalink / raw)
To: linux-wireless, tony, nsekhar
Cc: mturquette, mark.rutland, balbi, grant.likely, rob.herring,

linux-arm-kernel, coelho
In-Reply-To: <1372776948-24840-1-git-send-email-coelho@ti.com>
The platform_quirk element in the platform data was used to change the
way the IRQ is triggered. When set, the EDGE_IRQ quirk would change
the irqflags used and treat edge trigger differently from the rest.
Instead of hiding this irq flag setting behind the quirk, export the
whole irq_flags element and let the board file define what to use.
This will be more meaningful than driver-specific quirks when we
switch to DT.

Move the wl1251 part of the wl12xx platform data structure into a new
structure specifically for wl1251. Change the platform data built-in
block and board files accordingly.

* [PATCH v2 3/9] wlcore: remove pwr_in_suspend from platform data
From: Luciano Coelho @ 2013-07-02 14:55 UTC (permalink / raw)
To: linux-wireless, tony, nsekhar
Cc: mturquette, mark.rutland, balbi, grant.likely, rob.herring,
devicetree-discuss, linux-doc, linux-kernel, linux-omap,
linux-arm-kernel, coelho
In-Reply-To: <1372776948-24840-1-git-send-email-coelho@ti.com>
The pwr_in_suspend flag depends on the MMC settings which can be
retrieved from the SDIO subsystem, so it doesn't need to be part of
the platform data structure. Move it to the platform device data that
is passed from SDIO to wlcore.
