The 'wwan' devtype is meant for devices that require preconfiguration
and *every* time setup before the ethernet interface can be used, like
cellular modems which require a series of setup commands on serial ports
or other mechanisms before the ethernet interface will handle packets.
As ipheth only requires one-per-hotplug pairing setup with no
preconfiguration (like APN, phone #, etc) and the network interface is
usable at any time after that initial setup, remove the incorrect
devtype wwan.

Replace the arbitrary software-reset call from the device-probe
method, because:
- It is defective. To work correctly, it should be two byte writes,
not a single word write. As it stands, it does nothing.
- Some devices with sx150x expanders installed have their NRESET pins
ganged on the same line, so resetting one causes the others to reset -
not a nice thing to do arbitrarily!
- The probe, usually taking place at boot, implies a recent hard-reset,
so a software reset at this point is just a waste of energy anyway.
Therefore, make it optional, defaulting to off, as this will match the
common case of probing at powerup and also matches the current broken
no-op behavior.

If suspend called when kmmcd is doing host->ops->disable, as kmmcd already
increased host->en_dis_recurs to 1, the mmc_host_enable in suspend
function will return directly without increase the nesting_cnt, which will
cause the followed register access carried out to the disabled host.
mmc_suspend_host will enable host itself. No need to enable host before
it. Also works on kmmcd will get flushed in mmc_suspend_host, enable host
after it will be safe. So make the mmc_host_enable after it.

Previously, it was possible for ack_mmc_irqs() to clear pending interrupt
bits in the CTL_STATUS register, even though the interrupt handler had not
been called. This was because of a race that existed when doing a
read-modify-write sequence on CTL_STATUS. After the read step in this
sequence, if an interrupt occurred (causing one of the bits in CTL_STATUS
to be set) the write step would inadvertently clear it.
Observed with the TMIO_STAT_RXRDY bit together with CMD53 on AR6002 and
BCM4318 SDIO cards in polled mode.
This patch eliminates this race by only writing to CTL_STATUS and clearing
the interrupts that were passed as an argument to ack_mmc_irqs()."

Much (but not all) of the RTC state is kept in the RTC peripheral which
has its own power domain. Periodically (1 HZ), that state is synced from
one power domain to the other (peripheral->core). When we are resuming,
we need to wait for the sync to occur so that we don't get a mismatch of
reading undefined state in the rest of the driver.
Further, once the externally maintained bits have been synced back into
the core, we then need to restore the bits maintained in the core. In our
particular case, that is just the write completion interrupt bit.
If we don't do any of this, working with the RTC causes ~5 second delays
from time to time after waking up due to the write completion interrupt
never firing.

The introduction of support for SD combo cards breaks the initialization
of all CSR SDIO chips. The GO_IDLE (CMD0) in mmc_sd_get_cid() causes CSR
chips to be reset (this is non-standard behavior).
When initializing an SDIO card check for a combo card by using the memory
present bit in the R4 response to IO_SEND_OP_COND (CMD5). This avoids the
call to mmc_sd_get_cid() on an SDIO-only card.

ahci_do_softreset() compared the current time and deadline in reverse
when calculating timeout for SRST issue. The result is that if
@deadline is in future, SRST is issued with 0 timeout, which hasn't
caused any problem because it later waits for DRDY with the correct
timeout. If deadline is already exceeded by the time SRST is about to
be issued, the timeout calculation underflows and if the device
doesn't respond, timeout doesn't trigger for a _very_ long time.
Reverse the incorrect comparison order.

During suspend, the power.completion is expected to be set when a
device has not yet started suspending. Set it on init to fix a
corner case where a device is resumed when its parent has never
suspended.
Consider three drivers, A, B, and C. The parent of A is C, and C
has async_suspend set. On boot, C->power.completion is initialized
to 0.
During the first suspend:
suspend_devices_and_enter(...)
dpm_resume(...)
device_suspend(A)
device_suspend(B) returns error, aborts suspend
dpm_resume_end(...)
dpm_resume(...)
device_resume(A)
dpm_wait(A->parent == C)
wait_for_completion(C->power.completion)
The wait_for_completion will never complete, because
complete_all(C->power.completion) will only be called from
device_suspend(C) or device_resume(C), neither of which is called
if suspend is aborted before C.
After a successful suspend->resume cycle, where B doesn't abort
suspend, C->power.completion is left in the completed state by the
call to device_resume(C), and the same call path will work if B
aborts suspend.

Changing state to CLOSING when FIN is received causes A0 cards to
hang. Fix this by checking for A0 cards in FIN handling.

When the driver receives an AE for FIN received, it closes the
connection without changing the state of the connection in the
hardware to closing. By changing the state to closing, hardware will
do a normal close sequence.

During a stress testing in a large cluster, multiple close event are
detected and BUG() is hit in the iWARP core. The cause is that the
active node gave up while waiting for an MPA response from the peer
and tried to close the connection by sending RST. The passive node
driver receives the RST but is waiting for MPA response from the user.
When the MPA accept is received, the driver offloads the connection
and sends a CLOSE event. The driver gets an AE indicating RESET
received and also sends a CLOSE event, hitting a BUG().
Fix this by correcting RESET handling and sending CLOSE events.

Setting TX pause param writes to the wrong register location causing
the adapter to hang. Correct the define used to write the reigster.

niu_get_ethtool_tcam_all() assumes that its output buffer is the right
size, and warns before returning if it is not. However, the output
buffer size is under user control and ETHTOOL_GRXCLSRLALL is an
unprivileged ethtool command. Therefore this is at least a local
denial-of-service vulnerability.
Change it to check before writing each entry and to return an error if
the buffer is already full.
Compile-tested only.

Add a call to of_node_put in the error handling code following a call to
of_find_compatible_node.
The semantic match that finds this problem is as follows:

With the introduction of an AMBA PrimeCell per-cell block clock,
the pclk was left on after probe() unless explicitly disabled.
This clock is wired to the same clock on PL022 causing it to stay
always on since.
Fix this up properly by clocking the pclk whenever we want to
write into any PL022 registers and clocking the external clock
whenever we want to transmit messages on the bus.

When using PIO we have a timeout for the TX and RX FIFOs to ensure that
the data actually gets transferred. Warn if we hit that timeout - it
should never happen, but this makes sure we'll find out if it does.
