Reizer, Eyal d382b9c007 wlcore: add missing nvs file name info for wilink8
The following commits:
commit c815fdebef ("wlcore: spi: Populate config firmware data")
commit d776fc86b8 ("wlcore: sdio: Populate config firmware data")

Populated the nvs entry for wilink6 and wilink7 only while it is
still needed for wilink8 as well.
This broke user space backward compatibility when upgrading from older
kernels, as the alternate mac address would not be read from the nvs that
is present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin)
causing mac address change of the wlan interface.

This patch fix this and update the structure field with the same default
nvs file name that has been used before.

In addition, some distros hold a default wl1271-nvs.bin in the file
system with a bogus mac address (deadbeef...) that overrides the mac
address that is stored inside the device.
Warn users about this bogus mac address and use the internal mac address

Fixes: c815fdebef ("wlcore: spi: Populate config firmware data")
Fixes: d776fc86b8 ("wlcore: sdio: Populate config firmware data")

Bhumika Goyal 4f2949febc wlcore: add const to bin_attribute structure
Add const to bin_attribute structure as it is only passed to the
functions sysfs_{remove/create}_bin_file. The corresponding arguments
are of type const, so declare the structure to be const.

David S. Miller 24a72b77f3 wireless-drivers-next patches for 4.13
New features and bug fixes to quite a few different drivers, but
 nothing really special standing out.
 
 What makes me happy that we have now more vendors actively
 contributing to upstream drivers. In this pull request we have patches
 from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I
 still have patches from Marvell and Quantenna pending in patchwork. Now
 that's something comparing to how things looked 11 years ago in Jeff
 Garzik's "State of the Union: Wireless" email:
 
 https://lkml.org/lkml/2006/1/5/671
 
 Major changes:

Johannes Berg d58ff35122 networking: make skb_push & __skb_push return void pointers
It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.

Make these functions return void * and remove all the casts across
the tree, adding a (u8 *) cast only where the unsigned char pointer
was used directly, all done with the following spatch:

    @@
    expression SKB, LEN;
    typedef u8;
    identifier fn = { skb_push, __skb_push, skb_push_rcsum };
    @@
    - *(fn(SKB, LEN))
    + *(u8 *)fn(SKB, LEN)

    @@
    expression E, SKB, LEN;
    identifier fn = { skb_push, __skb_push, skb_push_rcsum };

    identifier fn = { skb_push, __skb_push, skb_push_rcsum };
    @@
    - fn(SKB, LEN)[0]

Note that the last part there converts from push(...)[0] to the
more idiomatic *(u8 *)push(...).

Johannes Berg 59ae1d127a networking: introduce and use skb_put_data()
A common pattern with skb_put() is to just want to memcpy()

this.

An spatch similar to the one for skb_put_zero() converts many
of the places using it:

Arnd Bergmann 4a4274bf2d wlcore: fix 64K page support
In the stable linux-3.16 branch, I ran into a warning in the
wlcore driver:

drivers/net/wireless/ti/wlcore/spi.c: In function 'wl12xx_spi_raw_write':
drivers/net/wireless/ti/wlcore/spi.c:315:1: error: the frame size of 12848 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Newer kernels no longer show the warning, but the bug is still there,
as the allocation is based on the CPU page size rather than the
actual capabilities of the hardware.

This replaces the PAGE_SIZE macro with the SZ_4K macro, i.e. 4096 bytes
per buffer.

Arend Van Spriel ca986ad9bc nl80211: allow multiple active scheduled scan requests
This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.

Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

Tony Lindgren 3e1ac93268 wlcore: Fix config firmware loading issues
Booting multiple wl12xx and wl18xx devices using the same rootfs is
a pain. You currently have to symlink the right nvs file depending
on the wl12xx type.

For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin
by default and trying to bring up a wl128x based device:

wlcore: ERROR nvs size is not as expected: 1113 != 912
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR NVS file is needed during boot
wlcore: ERROR firmware boot failed despite 3 retries

Note that wl18xx uses a separate config firmware wl18xx-conf.bin
that can be generated with tools using the following two git repos:

git.ti.com/wilink8-wlan/18xx-ti-utils
git.ti.com/wilink8-wlan/wl18xx_fw

So let's not configure the nvs file for wl18xx as it's not needed
AFAIK. If it turns out that we also need the nvs file for wl18xx,
we can just add it to the config firmware data for wl18xx.

Let's fix the issue by using the chip specific config firmware
data, and make sure we produce understandable warnings if something
is missing.

Eyal Reizer 01efe65aba wlcore: spi: add wl18xx support
Add support for using with both wl12xx and wl18xx.

- all wilink family needs special init command for entering wspi mode.
  extra clock cycles should be sent after the spi init command while the
  cs pin is high.
- Use inverted chip select for sending a dummy 4 bytes command that
  completes the init stage.

Maxim Altshul 5f6d4ca3c1 wlcore: Add support for get_expected_throughput opcode
Adding this opcode, allows the TI wireless driver,
to report throughput directly from FW to mac80211.

This is used mainly for mesh metric calculation.

Maxim Altshul 88f07e70d1 wlcore/wl18xx: Add functionality to accept TX rate per link
FW will provide a TX rate per link for each FW status,
and wlcore will be able to store the information for
the use of the mesh hwmp module.

This is used mainly in mesh.
Rates are reported when a mesh interface is up.

Maital Hahn c0174ee280 wlcore/wl18xx: mesh: added initial mesh support for wl8
1. Added support for interface and role of mesh type.
2. Enabled enable/start of mesh-point role,
   and opening and closing a connection with a mesh peer.
3. Added multirole combination of mesh and ap
   under the same limits of dual ap mode.
4. Add support for 'sta_rc_update' opcode for mesh IF.
   The 'sta_rc_update' opcode is being used in mesh_plink.c.
Add support in wlcore to handle this opcode correctly for mesh
(as opposed to current implementation that handles STA only).
5. Bumped the firmware version to support new Mesh functionality

Machani, Yaniv 585dfe813f wlcore: time sync : add support for 64 bit clock
Changed the configuration to support 64bit instead of 32bit
this in order to offload the driver from handling a wraparound.
