a28f6f27a8 ath10k: fix fetching channel during potential radar detection
Fetch target operating channel during potential radar detection when
the interface is just brought up, but no channel is assigned from
userspace. In this scenario rx_channel may not be having a valid pointer
hence fetch the target operating channel to avoid warnings as below
which can be triggered by the commands with DFS testing over longer run

comamnds:
iw wlan1 set type mesh
ifconfig wlan1 up (valid tgt_oper_chan only)
iw wlan1 cac trigger freq 5260 HT20 (valid rx_channel, tgt_oper_chan)
iw wlan1 cac trigger freq 5280 HT20
iw wlan1 cac trigger freq 5300 HT20

Once the CAC expires, current channel context will be removed and
we are only left with the fallback option of using 'target operating
channel'

Firmware and driver log:

51f60b8b69 ath10k: remove redundant error check
The check on ret for an error is redundant because it is already been

523f6701db ath10k: update available channel list for 5G radio
If a 5 GHz radio is calibrated for operation in both
the low band (channels 36 to 64) and high band(channels 100 to 169),
hardware allows operations in all the listed channels. However,
if the chip has been calibrated only for the low/high band and
a high/low band channel is configured, due to lack of calibration
there will be potentially invalid signal on those non calibrated channels.
To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for
those non calibrated channels by using low_5ghz_chan and high_5ghz_chan
values which we get from target through wmi service ready event.

Driver initialized flags are getting re initialized in handle_channel
in cfg80211. So calling the function to disable the non supported channel
from reg_notifier().

ca07baab0b ath10k: disallow DFS simulation if DFS channel is not enabled
If DFS is not enabled in hostapd (ieee80211h=0) DFS channels shall
not be available for use even though the hardware may have the capability
to support DFS. With this configuration (DFS disabled in hostapd) trying to
bring up ath10k device in DFS channel for AP mode fails and trying to
simulate DFS in ath10k debugfs results in a warning in cfg80211 complaining
invalid channel and this should be avoided in the driver itself rather than
false propogating RADAR detection to mac80211/cfg80211. Fix this by
checking for the first vif 'is_started' state(should work for client mode
as well) as all the vifs shall be configured for the same channel

628639b1c9 wil6210: use WMI_DISCONNECT_CMDID upon connect timeout
Upon connect timeout driver invokes _wil6210_disconnect() which iterates
over sta array and disconnects each connected sta. In practice, because
the connection is still ongoing and because cid is not yet allocated,
disconnect is not actually happening. This leaves FW in connecting
state while driver is in disconnected state.
To fix this, upon connect timeout, explicitly send WMI_DISCONNECT_CMDID
to FW to make sure it gets disconnected.

bcdd49b074 wil6210: store bss object and use cfg80211_connect_bss()
In a fast disconnect/connect sequence, cfg80211_connect_result() can
fail to find the bss object which the driver is connecting to. Detailed
sequence of events:
* Driver is connected in STA mode
* Disconnect request arrives from user space. Driver disconnects and
  calls cfg80211_disconnected() which adds new event to the
  cfg80211_wq worker thread
* Connect request arrives from user space. cfg80211_connect() stores
  ssid/ssid_len and calls rdev_connect()
* __cfg80211_disconnected() runs in worker thread and zero
  wdev->ssid_len
* Connect succeeds. Driver calls cfg80211_connect_result() which fails
  to find the bss because wdev->ssid_len is zero

To overcome this, upon connect request, store the bss object in the
driver and upon connect completion pass it to kernel using
cfg80211_connect_bss().

18618a9fba wil6210: missing reinit_completion in HALP voting
After setting HALP ICR bit, we keep it set until HALP unvote.
Masking HALP ICR should protect the driver from hitting the HALP ICR
over and over again. However, in case there is another MISC ICR
we will read the HALP ICR and issue a completion. This can lead to
a case where HALP voting is completed immediately, as the completion
is already set.
Reinit the HALP completion before the actual vote will clear previous
completions and protect from such cases.

9953a782f9 wil6210: bus_request platform operation refinement
The driver uses the bus_request platform operation to
request resources from the platform for a specific bandwidth.
Currently the driver requests resources for the maximum
theoretical bandwidth, when interface is brought up.
Refine this process a bit: now the driver will request a
small amount of resources when interface is up, and will only
issue the maximum request when connected.
This mechanism will be improved further in the future to make
more refined requests based on actual bandwidth.

583a662943 ath10k: improve the firmware download time for QCA6174
Len Brown reported the system resume time is taking more than 2 seconds in
bug - https://bugzilla.kernel.org/show_bug.cgi?id=185621.

The reason of the 2 seconds is due to the firmware download time.

The chip is booted up in the default reference clock speed to handle the
firmware download to chip memory and advanced to the support higher speed
clock to run the firmware after all. The default reference clock in the
hardware is slow so that the firmware download time is taking up to 2
seconds for a 600KB firmware file.

	[76798.334612] ath10k_pci : htt tx max num pending tx 1056

The resolution here is to enable the higher speed clock if the hardware
supported before the firmware download at BMI stage, so that the hardware
can handle the firmare download in a more efficient way. This can help to
improve the firmware download time from 2 seconds to around 500ms for the
same 600KB firmware file.

	[322859.093094] ath10k_pci htt tx max num pending tx 1056

The steps to advance to the higher speed clock is very hardware specific,
so adding the hardware ops for the hardware that can support this.

0878fff1f4 net: phy: Do not perform software reset for Generic PHY
The Generic PHY driver is a catch-all PHY driver and it should preserve
whatever prior initialization has been done by boot loader or firmware
agents. For specific PHY device configuration it is expected that a
specialized PHY driver would take over that role.

Resetting the generic PHY was a bad idea that has lead to several
complaints and downstream workarounds e.g: in OpenWrt/LEDE so restore
the behavior prior to 87aa9f9c61 ("net: phy: consolidate PHY
reset in phy_init_hw()").

Pull sched.h split-up from Ingo Molnar:
 "The point of these changes is to significantly reduce the
  <linux/sched.h> header footprint, to speed up the kernel build and to
  have a cleaner header structure.

  After these changes the new <linux/sched.h>'s typical preprocessed
  size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K
  lines), which is around 40% faster to build on typical configs.

  Not much changed from the last version (-v2) posted three weeks ago: I
  eliminated quirks, backmerged fixes plus I rebased it to an upstream
  SHA1 from yesterday that includes most changes queued up in -next plus
  all sched.h changes that were pending from Andrew.

  I've re-tested the series both on x86 and on cross-arch defconfigs,
  and did a bisectability test at a number of random points.

  I tried to test as many build configurations as possible, but some
  build breakage is probably still left - but it should be mostly
  limited to architectures that have no cross-compiler binaries
  available on kernel.org, and non-default configurations"

====================
pull-request: can 2017-03-03

this is a pull request for the upcoming v4.11 release.

There are two patches by Ethan Zonca for the gs_usb driver, the first one fixes
the memory used for USB transfers, the second one the coding style.

The last two patches are by me, one fixing a memory leak in the usb_8dev driver
the other a typo in the flexcan driver.

9383b33771 nfp: don't tell FW about the reserved buffer space
Since commit c0f031bc88 ("nfp_net: use alloc_frag() and build_skb()")
we are allocating buffers which have to hold both the data and skb to
be created in place by build_skb().

FW should only be told about the buffer space it can DMA to, that
is without the build_skb() headroom and tailroom.  Note: firmware
applications should validate the buffers against both MTU and
free list buffer size so oversized packets would not pass through
the NIC anyway.

16206524f6 net: ethernet: bgmac: init sequence bug
Fix a bug in the 'bgmac' driver init sequence that blind writes for init
sequence where it should preserve most bits other than the ones it is
deliberately manipulating.

The code now checks to see if the adapter needs to be brought out of
reset (where as before it was doing an IDM write to bring it out of
reset regardless of whether it was in reset or not).  Also, removed
unnecessary usleeps (as there is already a read present to flush the
IDM writes).
