2013-06-03cw1200: rename the cw1200 platform definition headerSolomon Peachy
My previous patch just moved the file, but it also needed to be renamed to conform to proper conventions. Signed-off-by: Solomon Peachy <pizza@shaftnet.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-06-03cw1200: Rework SDIO platform support to prevent build problems.Solomon Peachy
Based on discussions with And Bergmann, this patch changes the SDIO platform code to default to supporting the Sagrad devices, allowing for it to be overridden in board setup code. This renders the cw1200_sagrad module suplerflous, so it is now removed. It also moves the documentation that was in the cw1200_sagrad source to the platform header.

2013-06-03cw1200: Replace use of 'struct resource' with 'int' for GPIO fields.Solomon Peachy
The only advantage of 'struct resource' is that it lets us assign names as part of the platform data. Unfortunately since we are using platform data, we are already limited to a single instance of each driver, rendering this moot. So, replace the struct resources with ints, resulting in cleaner code. This was based on a suggestion from Arnd Bergmann. Signed-off-by: Solomon Peachy <pizza@shaftnet.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-06-03cw1200: Rename 'sbus' to 'hwbus'Solomon Peachy
This avoids problems when building on SPARC targets due to the driver calling the bus abstraction layer 'sbus'. Not that any SBUS-sporting SPARC targets are likely to have an SDIO controller, but this is the correct thing to do.

2013-05-29ath9k_hw: fix PA predistortion miscalibrationFelix Fietkau
If any bins from the training data are skipped (i != max_index), the calculated compensation curve gets distorted, and the signal will be wildly overamplified. This may be the cause of the reported hardware damage that was caused by PA predistortion (because of which PAPRD was disabled by default). When calculating the x_est, Y, theta values, the use of max_index and i was reversed. i points to the bin index whereas max_index refers to the index of the calculated arrays. Note that PA predistortion is still disabled, it will be re-enabled after it has been properly validated. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2013-05-29mac80211: always send multicast on CAB queueJohannes Berg
If the driver advertised support for a CAB queue, then we should put all multicast frames there, otherwise sending them can be racy with clients going to sleep while we TX a frame. To avoid this, always TX multicast frames on the multicast queue. It seems like even drivers not using the queue framework might want to do this which would mean also moving the IEEE80211_TX_CTL_SEND_AFTER_DTIM flag assignment, but it also seems that drivers behave differently here so that just moving it wouldn't be a good idea. It'd be better to modify those drivers to use the queue framework. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-05-29iwlwifi: mvm: Change number of DTIMs to skip semanticsAlexander Bondar
If skip over DTIMs is enabled the driver can specify number of DTIMs to skip. This parameter in host-device API implies number of DTIM periods to skip. For example, to skip one DTIM means sleep over two DTIM periods. Change semantics accordingly. Change this parameter's default value.
