2015-01-27ath10k: fix 10.2 fw stats parsingMichal Kazior
Both 10.2 firmware binaries 10.2-00082-4 and 10.2.4.20 have introduced ABI changes to fw_stats each. This caused fw_stats to output wrong data. Define new structures and use them to parse the statistics correctly. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-01-27ath10k: split fw pdev stats parsingMichal Kazior
This will make it easier to implement fw stats parsing for firmware 10.2. This also renames a few structures for consistency. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-01-27ath10k: add support for qca6174Michal Kazior
The QCA6174 in combination with new wmi-tlv firmware is capable of multi-channel, beamforming, tdls and other features. This patch just makes it possible to boot these devices and do some basic stuff like connect to an AP without encryption. Some things may not work or may be unreliable. New features will be implemented later. This will be addressed eventually with future patches.

2015-01-27ath10k: add support for qca6174 Rx descriptorsMichal Kazior
The QCA6174 chip has an extra 4 bytes in rx_ppdu_end structure which is used in htt_rx_desc and HTT Rx ring offset setup. This is necessary for correct Rx for QCA6174 (otherwise Rx descriptors are overwritten and corrupted). This means QCA988X will have an extra 4 byte padding in Rx descriptor layout which is harmless.

2015-01-27ath10k: reset chip before reading chip_id in probeMichal Kazior
There are some very rare cases with some hardware configuration that the device doesn't init quickly enough in which case reading chip_id yielded 0. This caused driver to subsequently fail to setup the device. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-01-27ath10k: implement rx reorder supportMichal Kazior
New firmware and firmware (qca6174 hw3.0+ and fw 266+) are capable of full aggregation rx reordering. If it's enabled then Rx is handled via a new, separate htt event. The rx ring behaviour is changed a little to support the new rx scheme. These changes shouldn't affect qca988x performance.

2015-01-27ath10k: introduce struct ath10k_skb_rxcbMichal Kazior
It doesn't make much sense to share the ath10k_skb_cb with Rx path. The Rx path doesn't need to keep any mac80211's data. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-01-15ath10k: prevent fw reg dump spamMichal Kazior
Originally the explicit fw register dump was added to wait_for_target_init because interrupts are masked early during power_up. Due to some changes in power_up/reset sequences sometimes when fw crashed ath10k would print the dump more than once via hif_stop -> warm_reset -> wait_for_target_init, possibly with different values each. Prevent this by doing the explicit fw register dump only during power_up instead of wait_for_target_init.

2015-01-15ath10k: fix duration calculation for quiet paramRajkumar Manoharan

2015-01-15ath10k: implement prb tmpl wmi commandMichal Kazior

2015-01-13ath10k: Fix potential Rx ring corruptionVasanthakumar Thiagarajan
When replenishing Rx buffers driver updates the address of the buffer and the index of rx buffer in rx ring to the firmware. Change in order by CPU can cause rx ring corruption. Add memory barrier before updating rx buffer index to guarantee the order. This could fix some instances of rx ring corruption due to done bit in rx attention flag not set.
