This patchset adds wl1271 support on ZOOM2/3 boards.
Only basic support is included; MMC power manipulation part is submitted separately as Runtime PM migration.
Changes since v4:
- Introduce a simple (yet safe) mechanism to pass platform-specific data to the driver, as suggested by Russell King. Currently only a single device is supported; multi-device support will be introduced only when/if required
Patches are based on 2.6.36-rc3 and tested on ZOOM3.
Thanks,
Ohad Ben-Cohen (7):

Make it possible for the set power method to indicate a
success/failure return value. This is needed to support
more complex power on/off operations such as bringing up
(and down) sdio functions.

Ohad Ben-Cohen
Add a simple mechanism to pass platform data to the
SDIO instances of wl12xx.
This way there is no confusion over who owns the 'embedded data',
typechecking is preserved, and no possibility for the wrong driver to
pick up the data.
Originally proposed by Russell King.

Add a simple mechanism to pass platform data to the
SDIO instances of wl12xx.
This way there is no confusion over who owns the 'embedded data',
typechecking is preserved, and no possibility for the wrong driver to
pick up the data.
Originally proposed by Russell King.

* [PATCH v5 5/7] wireless: wl1271: make ref_clock configurable by board
@ 2010-09-01 21:26 ` Ohad Ben-Cohen
0 siblings, 0 replies; 59+ messages in thread
From: Ohad Ben-Cohen @ 2010-09-01 21:26 UTC (permalink / raw)
To: linux-arm-kernel
The wl1271 device is using a reference clock that may change
between board to board.
Make the ref_clock parameter configurable by the board
files that set up the device, instead of having a hard coded
value in the driver source itself.

Add MMC3 support on ZOOM, which is hardwired to the wl1271 device.
The wl1271 is a 4-wire, 1.8V, embedded SDIO WLAN device with an
external IRQ line, and power-controlled by a GPIO-based fixed regulator.

Add MMC3 support on ZOOM, which is hardwired to the wl1271 device.
The wl1271 is a 4-wire, 1.8V, embedded SDIO WLAN device with an
external IRQ line, and power-controlled by a GPIO-based fixed regulator.

That was the original proposal from Russell;
AFAICT it's very similar to how platform device resources are handled
- it allows marking the original definition of the data as __initdata
(need to add that) thus freeing up its space after the initialization
phase completes. Later, in some scenarios, it might also allow to free
up the copied data (not done now, but the copying happen only once in
the lifetime of the driver so I'm fine with it).

The first copy is to allow platforms to have their data marked with
__initdata. The second copy probably isn't necessary, but avoids
problems where the driver may decide to modify the platform data.
We could instead make wl12xx_get_platform_data() return a const pointer
to its own internal storage instead, or ERR pointers for the various
failure cases.

The first copy is to allow platforms to have their data marked with
__initdata. The second copy probably isn't necessary, but avoids
problems where the driver may decide to modify the platform data.
We could instead make wl12xx_get_platform_data() return a const pointer
to its own internal storage instead, or ERR pointers for the various
failure cases.

Sorry for pushing at this, but why would you mark data that's meant to
be used after init phase as __initdata?

I can remove the first copying as well if Russell is ok with it.
Both ways work for us.

Because you may have many instances of the data (due to multiple platform
support), and only need one of them at run-time.

I personally think it's not worth it. This copying basically happens
only once and this point is soooo irrelevant. My position therefore
is: let's get the current implementation in, and if Michal is
uncomfortable with that, he can come up with the patch. Let's
concentrate on the real problems.

Tony, John, let me please suggest merging this through the wireless tree.
wl1271 is a moving target - it keeps changing in the wireless tree and
merging this patchset there will allow wl1271 developers to have
everything in a single tree (and prevent merge conflicts in
linux-next).
If that's ok with you, I will rebase this on top of wireless-testing
and resubmit.

Yes sounds good to me, I think there's still at least some platform_data

This becomes an issue when compiling in support for multiple
boards.. All the data that's not in use for the booted board
should be __initdata.
