* brcmfmac: allocate struct brcmf_pub instance using wiphy_new()Arend Van Spriel2018-03-271-6/+11
| | | | | | | | | | | | | Rework the driver so the wiphy instance holds the main driver information in its private buffer. Previously it held struct brcmf_cfg80211_info instance so a bit of reorg was needed. This was done so that the wiphy name or its parent device can be shown in debug output.

| | | | | | | | | | | | | The firmware may have supplicant code built-in. This is detected by the driver and indicated in the wiphy features flags. User-space can use this flag to determine whether or not to provide the pre-shared key material in the nl80211 CONNECT command.

* brcmfmac: add support multi-scheduled scanArend Van Spriel2017-06-131-2/+4
| | | | | | | | | | | | | | | | | | | | This change adds support for multi-scheduled scan in the driver. It currently relies on g-scan support in firmware and will set struct wiphy::max_sched_scan_reqs accordingly. This is limited to 16 concurrent requests. The firmware currently has a limit of 64 channels that can be configured for all requests in total regardless whether there are duplicates. So if a request uses 35 channels there are 29 channels left for another request. When user-space does not specify any channels cfg80211 will add all channels defined by the wiphy instance to the request, which makes reaching the limit rather easy for dual-band devices.

* brcmfmac: Change vif_event_lock to spinlockmhiramat@kernel.org2016-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change vif_event_lock to spinlock from mutex, since this lock is used in wait_event_timeout() via vif_event_equals(). This caused a warning report as below. As far as I can see, this lock protects regions where updating structure members, not function calls. Also, since those regions are not called from interrupt handlers (of course, it was a mutex), spin_lock is used instead of spin_lock_irqsave.
