ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs
This patch series covers both ASoC and extcon subsystems and fixes an
interaction between the HPDET function and the headphone outputs - we
really shouldn't run HPDET while the headphone is active. The first
patch is a refactoring to make the extcon side easier.

When building ax88796 on an ARM platform with 64-bit resource_size_t,
we currently get
drivers/net/ethernet/8390/ax88796.c:875: undefined reference to `__aeabi_uldivmod'
because we do a division on the length of the MMIO resource.
Since we know that this resource is very short, using an
"unsigned long" instead of "resource_size_t" is entirely
sufficient, and avoids this link-time error.

This fixes 2 issues regarding bnx2x's status blocks:
1. ethtool -c caused corruption of status blocks in FW RAM.
2. when using multi-CoS, the configuration of the timeout values of
status blocks is incorrect, harming the coalescing of interrupts
for such CoSs.

When loading after UNDI (e.g., Boot from SAN) the UNDI does not
gracefully yield its resources; The bnx2x driver handles that release
itself.
During the manipulation required to release those resources, it's possible
for the UNDI to try and write to memory regions which are no longer accessible,
causing the PCI bus to prevent further writes from the chip.
This would in turn cause DMAE timeouts later on in the driver, as the driver
will be unable to use the chip's DMA engines.
This patch prevents the chip from actually writing through the PCI bus
in said scenario, thus allowing the release without the unfortunate by-product.

The PF driver does not check if the administrator has already set a VF
VLAN via the PF driver before setting the new VLAN. This results in
the following scenario:
A) Administrator sets VF <n> to VLAN 100
B) Administrator sets VF <x> to VLAN 100
C) Administrator sets VF <n> to VLAN 200
D) The VF <n> driver continues to be able to receive traffic on VLAN
100 because the VLVFB pool enable bit for that VF was left set
instead of being cleared as it should be.
This fix ensures that the old VLAN filter for VF <n> is first removed
and the pool bit enable for VF <n> is cleared so that it no longer
receives traffic on VLAN 100.

This patch actually reverts:
igb: Support using build_skb in the case that jumbo frames are disabled
The reason for reverting this patch is that it can lead to data corruption.
The following flow was pointed out by Ben Hutchings:
1. skb is forwarded to another device
2. Packet headers are modified and it's put into a queue
3. Second packet is received into the other half of this page
4. Page cannot be reused, so is DMA-unmapped
5. The DMA mapping was non-coherent, so unmap copies or invalidates
cache
The headers added in step 2 get trashed in step 5.

mvneta_tx() was using a static tx queue number causing crashes as
soon as a little bit of traffic was sent via the interface, because
it is normally expected that the same queue should be used as in
dev_queue_xmit().
As suggested by Ben Hutchings, let's use skb_get_queue_mapping() to
get the proper Tx queue number, and use alloc_etherdev_mqs() instead
of alloc_etherdev_mq() to create the queues.
Both my Mirabox and my OpenBlocks AX3 used to crash without this patch
and don't anymore with it. The issue appeared in 3.8 but became more
visible after the fix allowing GSO to be enabled.
Original work was done by Dmitri Epshtein and Thomas Petazzoni. I
just adapted it to take care of Ben's comments.

The mvmdio driver uses the phylib API, so it should select the PHYLIB
symbol, otherwise, a build with mvmdio (but without mvneta) fails to
build with undefined symbols such as mdiobus_unregister, mdiobus_free,
etc.
The mvneta driver does not use the phylib API directly, so it does not
need to select PHYLIB. It already selects the mvmdio driver anyway.
Historically, this problem is due to the fact that the PHY handling
was originally part of mvneta, and was later moved to a separate
driver, without updating the Kconfig select statements
accordingly. And since there was no functional reason to use mvmdio
without mvneta, this case was not tested.

The cnic module is responsible for initializing various bnx2x structs
via callbacks provided by the bnx2x module.
One such struct is the queue object for the FCoE queue.
If a device is working in AFEX mode and its configuration allows FCoE yet
the cnic module is not loaded, it's very likely a null pointer dereference
will occur, as the bnx2x will erroneously access the FCoE's queue object.
Prevent said access until cnic properly registers itself.

'link' field of 'struct phy_device' is merely *int* (having values 0 and 1) and

rid of incorrectly used PHY_DOWN value in assignments/comparisons.

At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its
mask in EESIPR register. I can 100% reproduce it with the following scenario:
target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device
but doesn't get a proper reply and then succeeds with on-board SMC chip; then
I login and try to bring up the SoC Ether device with 'ifconfig', and I get
an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt
mask in EESIPR register is all 0), if that interrupt is accompanied by a pending
EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx()
because sh_eth_ring_init() hasn't been called yet!
The solution I worked out is the following: in sh_eth_interrupt(), mask the
interrupt status from EESR register with the interrupt mask from EESIPR register
in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit
in this mask set because we always need to fully handle EESR.ECI interrupt in
sh_eth_error() in order to quench it (as it doesn't get cleared by just writing
1 to the this bit as all the other interrupts).
While at it, remove unneeded initializer for 'intr_status' variable and give it
*unsigned long* type, matching the type of sh_eth_read()'s result; fix comment.

The code handling the absent LINK signal (or the absent PSR register -- which
reflects the state of this signal) is quite naive and has probably never really
worked. It's probably enough to say that this code is executed only on the LINK
change interrupt (sic!) but even if we actually have the signal and choose to
ignore it (it might be connected to PHY's link/activity LED output as on the
Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update
'mdp->link' gets executed later than the LINK change interrupt where it is
checked, and so RX/TX never get enabled via ECMR register.
So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen
not to be used) or PSR register is absent, and enable/disable RX/TX directly in
sh_eth_adjust_link() in this case.

WOL is broken because the magic packet status bit is getting set rather
than the enable bit. The PMT interrupt is not getting serviced because
the PMT interrupt is also enabled on the global interrupt, but not
cleared by the global interrupt and the global interrupt is higher
priority. This fixes both of these issues to get WOL working.
There's still a problem with receive after resume, but at least now we
can wake-up.

If skb allocation for the rx ring fails repeatedly, we can reach a point
were the ring is empty. In this condition, the driver is out of sync with
the h/w. While this has always been possible, the removal of the skb

The sky2 driver doesn't count the Receive Overflows because the MAC
interrupt for this event is not set in the MAC's interrupt mask.
The MAC's interrupt mask is set only for Transmit FIFO Underruns.
Fix: The correct setting should be (GM_IS_TX_FF_UR | GM_IS_RX_FF_OR)
Otherwise the Receive Overflow event will not generate any interrupt.
The Receive Overflow interrupt is handled correctly
