clk_{un}prepare is mandatory for platforms using common clock framework.
Since these drivers are used by SPEAr platform, which supports common
clock framework, add clk_{un}prepare() support for them. Otherwise
the clocks are not correctly en-/disabled and ethernet support doesn't
work.

__lpc_handle_xmit() has two bugs :
1) It can leak skbs in case TXSTATUS_ERROR is set
2) It can wake up txqueue while no slot was freed.

lpc_eth does a copy of transmitted skbs to DMA area, without checking
skb lengths, so can trigger buffer overflows :
memcpy(pldat->tx_buff_v + txidx * ENET_MAXF_SIZE, skb->data, len);
One way to get bigger skbs is to allow MTU changes above the 1500 limit.
Calling eth_change_mtu() in ndo_change_mtu() makes sure this cannot
happen.

MSI is enabled by default for most of the 4th generation
chips. Add this for AR9462 - this fixes PowerSave operation,
the chip was not entering Network-Sleep mode earlier.
With proper powering down of the MAC now, power consumption
in associated state is reduced considerably.

Currently 4 channels are scanned per scan command. if scan request
is issued by user during Tx traffic, radio will be out of channel
for "4 * per_chan_scan_time" for each scan command and will not be
able to receive Rx packets. This adds delay in data traffic. We can
minimize it by reducing number of channels scanned per scan command
in this scenario.
We can not always scan 1 channel per scan command due to limitation
of number of command buffers. So we add code to decide number of
channels scanned per scan command in associated state.

If scan operation is started when Tx traffic is already running,
driver locks Tx queue until it gets completed. With this logic
there is a delay for Tx packets.
This patch implements new approach to give Tx path higher priority
in this case. Driver internally sends multiple synchronous scan
commands to firmware when scan is requested by user. Now we will
make sure that Tx queue is empty everytime before sending next scan
command. If Tx queue isn't empty scan command will be postponsed by
20msec. This rule will be followed until Tx queue becomes empty or
timeout of 1 second happens. In case of timeout scan operation will
be aborted.

Currently the scan time per channel for active scanning is set to
200ms. It takes quite a while to finsh scanning on all channels,
especially with a dual band configuration.
Change the per channel scan time settings to the following values:
passive scan: 110ms
active scan: 30ms
specific scan: 30ms
Above settings have been tested on x86 and arm platforms.

commit 3fa2a1df909 (virtio-net: per cpu 64 bit stats (v2)) added a race
on 32bit arches.
We must use separate syncp for rx and tx path as they can be run at the
same time on different cpus. Thus one sequence increment can be lost and
readers spin forever.

While reworking the r8169 driver a few months ago to perform the
smallest amount of work in the irq handler, I took care of avoiding
any irq mask register operation in the slow work dedicated user
context thread. The slow work thread scheduled an extra round of NAPI
work which would ultimately set the irq mask register as required,
thus keeping such irq mask operations in the NAPI handler.
It would eventually race with the irq handler and delay NAPI execution
for - assuming no further irq - a whole ksoftirqd period. Mildly a
problem for rare link changes or corner case PCI events.
The race was always lost after the last bh disabling lock had been
removed from the work thread and people started wondering where those
pesky "NOHZ: local_softirq_pending 08" messages came from.
Actually the irq mask register _can_ be set up directly in the slow
work thread.

Fix regresson since the introduction of command stream checking on
evergreen (thread referenced below). Issue is cause by ddx allocating
bo with formula width*height*bpp while programming the GPU command
stream with ALIGN(height, 8). In some case (where page alignment does
not hide the extra size bo should be according to height alignment)
the kernel will reject the command stream.
This patch reprogram the command stream to slice - 1 (slice is
a derivative value from height) which avoid rejecting the command
stream while keeping the value of command stream checking from a
security point of view.
This patch also fix wrong computation of layer size for 2D tiled
surface. Which should fix issue when 2D color tiling is enabled.
This dump the radeon KMS_DRIVER_MINOR so userspace can know if
they are on a fixed kernel or not.

This reverts commit 9e612a008fa7fe493a473454def56aa321479495.
It incorrectly finds VGA connectors where none are attached, apparently
not noticing that nothing replied to the EDID queries, and happily using
the default EDID modes that have nothing to do with actual hardware.
That in turn then causes X to fall down to the lowest common
denominator, which is usually the default 1024x768 mode that is in the
default EDID and pretty much anything supports).
I'd suggest that if not relying on the HDP pin, the code should at least
check whether it gets valid EDID data back, rather than just assume
there's something on the VGA connector.

When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:
Queue 2 stuck for 10000ms
This doesn't seem to fix the higher queues that get stuck
from time to time.

Add vga_switcheroo_get_client_state() to get the current state of the
client. This is necessary to determine the proper initial state of
audio clients in HD-audio driver.

This reverts commit efa230f2c68abab817f13473077f8d0cc74f43f3.
BQL doesn't work with how this driver currently only takes TX
interrupts every 1/4 of the TX ring. That behavior needs to be fixed,
but that's a larger non-trivial task and for now we have to revert
BQL support as this makes the device currently completely unusable.

Don't spew errors when we can't find the NVS file in wlcore. Instead
fail the wl12xx boot HW op if the NVS isn't found.
Take this opportunity to remove some dead code from register_hw()
which looks for the NVS again needlessly.

Give all wl18xx phy module paramters -1 as a default value, indicating
the paramter was not set. Add previous default values to the default
18xx priv conf structure.
Remove the board_type field from wl18xx priv. The field with the same
name inside the phy conf is good enough for our purposes.

wl18xx_conf_phy represents part of the FW native wl18xx_mac_and_phy_params
structure. Remove it and replace the phy part of the wl18xx conf with the
FW bound structure. This allows us to set/override all members.
Increment the wlconf version to ensure compatibility with the new
structure

Instead of using the hardcoded configuration structure, try to read it
from a "firmware" file called wl18xx-conf.bin. If the file doesn't
exist, fall back to the hardcoded version. If the file exists but is
illegal, bail out.

Since we are now going to export the conf structure and read it from a
file, it should be packed to avoid surprises with padding bytes.
