With RGMII, we need a 1.5 to 2ns skew between clock and data lines. The
VSC8601 can handle this internally. While the VSC8601 can set more
fine-grained delays, the standard skew settings work out of the box.
The same heuristic is used to determine when this skew should be enabled
as in vsc824x_config_init().
Tested on custom board with AM3352 SOC and VSC801 PHY.

Calling napi_hash_del() before netif_napi_del() is dangerous

It seems many drivers do not respect napi_hash_del() contract.
When napi_hash_del() is used before netif_napi_del(), an RCU grace
period is needed before freeing NAPI object.

This option was added in 6a89a314ab107a12af08c71420c19a37a30fc2d3 to
allow use of the devm_gpio_* functions without CONFIG_GPIOLIB.
However, only a few months later in
b69ac52449c658b7ac40034dc3c5f5f4a71a723d, CONFIG_GPIOLIB was added
as a dependency, defeating the original purpose of this option.
Instead of that patch, the original commit could have just been
reverted (and in fact was partially so in
403c1d0be5ccbd750d25c59d8358843a81e52e3b). Further, since this
option has a dependency on HAS_IOMEM, even though it does not
require it, it causes build failures when !HAS_IOMEM (e.g. in a
uml build).
Fix that by completely removing the option, in essence completing
the reversion of the original commit.

This patch fixes the following
1. When interface is being teardown and queues are being cleaned up,
free pending SKBs that are in SQ which are either not transmitted
or freed as NAPI is disabled by that time.
2. While interface initialization, delay CFG_DONE notification till
the end to avoid corner cases where TXQs are enabled but CQ
interrupts are not which results blocking transmission and kicking
off watchdog.
3. Check for IFF_UP while re-enabling RBDR interrupts from tasklet.

This patch fixes multiple issues
1. Convert all driver statistics to percpu counters for accuracy.
2. To avoid multiple CQEs posted by a TSO packet appended to HW,
TSO pkt's SQE has 'post_cqe' not set but a dummy SQE is added
for getting HW transmit completion notification. This dummy
SQE has 'dont_send' set and HW drops the pkt pointed to in this
thus Tx drop counter increases. This patch fixes this by subtracting
SW tx tso counter from HW Tx drop counter for actual packet drop counter.
3. Reset all individual queue's and VNIC HW stats when interface is going down.
4. Getrid off unnecessary counters in hot path.
5. Bringout all CQE error stats i.e both Rx and Tx.

Programming LMAC credits taking 9K frame size by default is incorrect
as for an interface which is one of the many on the same BGX/QLM
no of credits available will be less as Tx FIFO will be divided
across all interfaces. So let's say a BGX with 40G interface and another
BGX with multiple 10G, bandwidth of 10G interfaces will be effected when
traffic is running on both 40G and 10G interfaces simultaneously.
This patch fixes this issue by programming credits based on netdev's MTU.
Also fixed configuring MTU to HW and added CQE counter for pkts which

Since commit c4dd1ba355aae2bc3d1213da6c66c53e3c31e028
("mfd: stmpe: Add reset support for all STMPE variant")
we're resetting the STMPE expanders before use.
This caused a regression on the STMP2401 on the Nomadik
NHK8815:
stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101
nmk-i2c 101f8000.i2c0: write to slave 0x43 timed out
nmk-i2c 101f8000.i2c0: no ack received after address transmission
stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101
nmk-i2c 101f8000.i2c0: write to slave 0x44 timed out
nmk-i2c 101f8000.i2c0: no ack received after address transmission
It turns out that we start to poll for the reset bit to
go low again too quickly: the STMPE2401 is not yet online and
ready to be asked for the status of the RESET bit.
By introducing a 10ms delay before starting to hammer
the register for information, we get back to normal:
stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101
stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101

also put the device in reset state.
Due to the resetting of device, system cannot enter S3/S0ix

and serial console both hang. The resetting of device is not
needed while going to suspend. Hence remove this code.

There are a few issues on Intel Kaby Lake PCH-H properties added by
commit a6a576b78e09 ("mfd: lpss: Add Intel Kaby Lake PCH-H PCI IDs"):
- Input clock of I2C controller on Intel Kaby Lake PCH-H is 120 MHz not
133 MHz. This was probably copy-paste error from Intel Broxton I2C
properties.
- There is no default I2C SDA hold time specified which is used when
ACPI doesn't provide it. I got information from Windows driver team
that Kaby Lake PCH-H can use the same configuration than Intel
Sunrisepoint PCH.
- Common HS-UART properties are not used.
Fix these by reusing the Sunrisepoint properties on Kaby Lake PCH-H.

specified in the VBT
My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT
port information apparently didn't survive the reality of buggy VBTs.
In this particular case we have a machine with a natice HDMI port, but
the VBT tells us it's a DP++ port based on its capabilities.
The dvo_port information in VBT does claim that we're dealing with a
HDMI port though, but we have other machines which do the same even
when they actually have DP++ ports. So that piece of information alone
isn't sufficient to tell the two apart.
After staring at a bunch of VBTs from various machines, I have to
conclude that the only other semi-reliable clue we can use is the
presence of the AUX channel in the VBT. On this particular machine
AUX channel is specified as zero, whereas on some of the other machines
which listed the DP++ port as HDMI have a non-zero AUX channel.
I've also seen VBTs which have dvo_port a DP but have a zero AUX
channel. I believe those we need to treat as DP ports, so we'll limit
the AUX channel check to just the cases where dvo_port is HDMI.
If we encounter any more serious failures with this heuristic I think
we'll have to have to throw it out entirely. But that could mean that
there is a risk of type 1 DVI dongle users getting greeted by a
black screen, so I'd rather not go there unless absolutely necessary.

This patch makes sure all allocated resources are freed before freeing

The IRQ affinity entry is not needed after the irq notifier patch has been
added to the hfi1 driver.
The irq affinity settings for SDMA engine should be set using the standard
/proc/irq/<N>/ interface.

The initial code for rdmavt carried with it a restriction that was a
vestige from the qib driver, that to dma map a page it had to be less
than a page size. This is not the case on modern hardware, both qib and
hfi1 will be just fine with unaligned map requests.
This fixes a 4.8 regression where by an IPoIB transfer of > PAGE_SIZE
will hang because the dma map page call always fails. This was
introduced after commit 5faba5469522 ("IB/ipoib: Report SG feature
regardless of HW UD CSUM capability") added the capability to use SG by
default. Rather than override this, the HW supports it, so allow SG.
