2016-04-12wil6210: basic PBSS/PCP supportLior David
PBSS (Personal Basic Service Set) is a new BSS type for DMG networks. It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. For example, stations inside a PBSS can communicate directly, and the PCP role can be transferred between stations. This change adds PBSS support, and has 2 main parts: 1. When starting an AP, add an option to start as a PCP instead. This is implemented by a new PBSS flag which is passed as part of the cfg80211_ap_settings structure. 2. When connecting to a BSS, add an option to connect to a PCP instead of an AP. This is again implemented by a new PBSS flag, added to the cfg80211_connect_params structure.

2016-04-05wil6210: disable PCIe relaxed orderingMaya Erez
In previous commit cd958296acba ("wil6210: enable WA for PCIe HW errata") relaxed ordering (bit 5) was set, in addition to the 'No snoop" setting. Enabling relaxed ordering can cause a race condition between the write transactions and interrupts when using INT instead of MSI. As relaxed ordering is not required to resolve the PCIe HW issue, it should be disabled.

2016-04-05cfg80211: basic support for PBSS network typeLior David
PBSS (Personal Basic Service Set) is a new BSS type for DMG networks. It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. PBSS support is mandatory for 11ad devices. Add support for PBSS by introducing a new PBSS flag attribute. The PBSS flag is used in the START_AP command to request starting a PCP instead of an AP, and in the CONNECT command to request connecting to a PCP instead of an AP.

2016-04-05wil6210: switch to generated wmi.hLior David
Switch to auto-generated version of wmi.h which is maintained by FW team. This will allow better sync between teams in the future and avoid bugs because of unexpected API changes. The wmi.h will have many differences but most are cosmetic. It also includes these real differences: 1. is_go parameter added to BCON_CTRL and START_PCP commands. 2. max_rx_pl_per_desc added to CFG_RX_CHAIN command. 3. various small API updates that are not currently used by driver.

2016-04-05wil6210: add support for discovery mode during scanLior David
Add support for discovery mode during scan. When discovery mode is active, station transmits special beacons while scanning. This can optimize the scan mainly when there is only one AP/PCP around. Discovery mode is implicitly used by firmware during P2P search. Since there is currently no use case where user space has a reason to directly control discovery mode, we expose it only through a debugfs flag. Also fix name confusion in the wmi_scan_type enumeration. The type previously called WMI_LONG_SCAN is actually WMI_ACTIVE_SCAN.

2016-04-05wil6210: remove BACK RX and TX workersMaya Erez
WMI synchronous handling has changed and WMI calls that provide a buffer for the reply are completed in the WMI interrupt context. This allows sending the RX and TX BACK commands from the WMI event handler without the need for the worker thread. This is a better approach as it can decrease the handshake time in the connect flow and prevent race conditions in case of fast disconnects. An example for such a race is handling of wil_back_rx_handle during a disconnect event, as wil_back_rx_handle is not protected by the wil mutex and a disconnect can be handled after sta->status is verified as connected.

2016-04-05wil6210: protect synchronous wmi commands handlingMaya Erez
In case there are multiple WMI commands with the same reply_id, the following scenario can occur: - Driver sends the first command to the device - The reply didn’t get on time and there is timeout - Reply_id, reply_buf and reply_size are set to 0 - Driver sends second wmi command with the same reply_id as the first - Driver sets wil->reply_id - Reply for the first wmi command arrives and handled by wmi_recv_cmd - As its ID fits the reply_id but the reply_buf is not set yet it is handled as a reply with event handler, and WARN_ON is printed This patch guarantee atomic setting of all the reply variables and prevents the above scenario.

In case of quick disconnect / connect events for the same station, spin_lock(&txdata->lock) can be called during the lock initialization in the vring init function. To prevent such a race, the TX vrings spin lock should be initialized once during wil6210 driver initialization.

2016-03-23cnss: Vote for the WLAN antenna switch regulatorYue Ma
In some targets, explicitly turning on/off the regulator for WLAN antenna switch is needed to enable/dsiable antenna sharing capacity. Hence add the change to achieve this based on device tree option. Change-Id: Ic04019cbe9c42bc92a65f308f56f307c52346d92 Signed-off-by: Yue Ma <yuem@codeaurora.org>

2016-03-23cnss-sdio: Dynamically allocate ramdump memoryKomal Seelam
Existing solution to reserve the memory region for CNSS ramdump collection has it's own limitations because of reserving the memory region for each platforms even before CNSS driver is probed. Add implementation to allocate the required memory for CNSS ramdump using dma_alloc_coherent API and update the physical address in dump table so that tools can find the starting address of the CNSS ramdump in the crash dump.

Register subsystem device for SSR recovery. Create ramdump device for cnss fw dump collection. Implement cnss SSR API to wlan sdio driver. CRs-Fixed: 944010 Change-Id: If81fd84bb6080df73b12f235a2aa0eff6f717ce1 Signed-off-by: Liangwei Dong <liangwei@codeaurora.org>
2016-03-23cnss: Remove unwanted pci resume call during system resumeKomal Seelam
msm_pcie_pm_control is an exported pcie API to request for PCIe link suspend/resume for auto suspend feature. The auto suspend feature now moved to use the runtime pm framework which is handles the PCIe link suspend/resume as part of runtime pm callbacks. Hence removing the unwanted resume call in system resume callback. Change-Id: I0e56f228f819eb3a6fc6a0c732b4e5adc0cc82b0 CRs-Fixed: 952659 Signed-off-by: Komal Kumar <kseelam@codeaurora.org>
2016-03-23cnss: Recover PCIe configuration space during normal WLAN recoveryYue Ma
During normal SSR there is a corner case that somehow WLAN driver fails to read PCIe configuration space which can result corruption when it tries to save it. Hence recover PCIe configuration space from shadow registers as well in normal SSR. This is same as the recovery for real PCIe link down.

2016-03-23net: wireless: decouple cnss crypto from cnss memory pre-allocSarada Prasanna Garnayak
The cnss crypto add support for wlan host driver for security Protocol and cipher key generation where cnss memory pre-alloc feature enable wlan driver to use pre allocated memory for its internal usage and release it to back to pre-allocated pool. Decouple cnss crypto from cnss memory pre-alloc and add kernel config flag for this crypto module compilation and update the defocnfig of required targets.
