3719c17e18 wlcore/wl18xx: fw logger over sdio
Enable the FW Logger to work over the SDIO interface in addition to over UART
interface. In the new design we use fw internal memory instead of packet ram
that was used in older (wl12xx) design. This change reduces the impact on TP
and stability.

A new event was added to notify fw logger is ready for reading. Dynamic
configuration to debugfs was added as well.

9b2761cb72 wlcore/wl12xx: spi: fix oops on firmware load
The maximum chunks used by the function is
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE + 1).
The original commands array had space for
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE) commands.
When the last chunk is used (len > 4 * WSPI_MAX_CHUNK_SIZE), the last
command is stored outside the bounds of the commands array.

3b06d27795 cfg80211: Add multiple scan plans for scheduled scan
Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.

When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

7845af35e0 wlcore: add p2p device support
When starting a p2p mgmt interface, enable its device role. This
allows us to keep the sta role disabled and scan on the dev role.

In general, p2p management interfaces cannot send vif-specific commands
to FW, as the vif role id is invalid. Only off-channel data and scans
happen on this vif, so most ops are not relevant.

If the vif is a p2p mgmt vif, block some mac80211 ops.

Configure rate policies for p2p mgmt interface, as
otherwise p2p packets come out with arbitrary rates.

Since wpa_supplicant currently doesn't support standalone
p2p device mode (without another attached managed interface),
add p2p device to the allowed interface combinations without
decreasing the allowed station count.

Moreover, increase the station count in some cases, as AP
mode usually starts as station interface, and the AP interface
is now different from the p2p management one).

30686bf7f5 mac80211: convert HW flags to unsigned long bitmap
As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

 - More graphics DT pieces falling into place on Exynos, bridges, clocks.
 - Plenty of DT updates for Qualcomm platforms for various IP blocks
 - Some churn on Tegra due to switch-over to tool-generated pinctrl data
 - Misc fixes and updates for Atmel at91 platforms
 - Various DT updates to add IP block support on Broadcom's Cygnus platforms
 - More updates for Renesas platforms as DT support is added for various IP

7b6249bba9 Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
  * VHT support for TDLS and IBSS (conditional on drivers though)
  * first TX performance improvements (the biggest will come later)
  * many suspend/resume (race) fixes
  * name_assign_type support from Tom Gundersen

83c3a7d4ac wlcore: remove wl12xx_platform_data
Now that we have wlcore device-tree bindings in place
(for both wl12xx and wl18xx), remove the legacy
wl12xx_platform_data struct, and move its members
into the platform device data (that is passed to wlcore)

Davinci 850 is the only platform that still set
the platform data in the legacy way (and doesn't
have DT bindings), so remove the relevant
code/Kconfig option from the board file (as suggested
by Sekhar Nori)

Since no one currently uses wlcore_spi, simply remove its
platform data support (DT bindings will have to be added
if someone actually needs it)

44486b48b0 wl12xx: use frequency instead of enumerations for pdata clocks

6f921fab58 wlcore: set irq_trigger in board files instead of hiding behind a quirk
The platform_quirk element in the platform data was used
to change the way the IRQ is triggered.  When set,
the EDGE_IRQ quirk would change the irqflags used
and treat edge trigger differently from the rest.

Instead of hiding this irq flag setting behind the quirk,
have the board files set the irq_trigger explicitly.

This will allow us to use standard irq DT definitions
later on.

a3fa71c40f wl18xx: show rx_frames_per_rates as an array as it really is
In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number.  This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data).  Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.

This bug has been found by adding a __printf attribute to
wl1271_format_buffer.  gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

6c09e791b2 cfg80211: Allow NL80211_ATTR_IFINDEX to be added to vendor events
This modifies cfg80211_vendor_event_alloc() with an additional argument
struct wireless_dev *wdev. __cfg80211_alloc_event_skb() is modified to
take in *wdev argument, if wdev != NULL, both the NL80211_ATTR_IFINDEX
and wdev identifier are added to the vendor event.

These changes make it easier for drivers to add ifindex indication in
vendor events cleanly.

This also updates all existing users of cfg80211_vendor_event_alloc()
and __cfg80211_alloc_event_skb() in the kernel tree.
