The DRA74/72 control module pins have a weak pull up and pull down.
This is configured by bit offset 17. if BIT(17) is 1, a pull up is
selected, else a pull down is selected.
However, this pull resisstor is applied based on BIT(16) -
PULLUDENABLE - if BIT(18) is *0*, then pull as defined in BIT(17) is
applied, else no weak pulls are applied. We defined this in reverse.

In the recent commit b50a6c584bb4 "Clear MMCR2 when enabling PMU", I
screwed up the handling of MMCR2 for tasks using EBB.
We must make sure we set MMCR2 *before* ebb_switch_in(), otherwise we
overwrite the value of MMCR2 that userspace may have written. That
potentially breaks a task that uses EBB and manually uses MMCR2 for
event freezing.

While we already had various kind of bugs in that area
ec0223ec48a9 ("net: sctp: fix sctp_sf_do_5_1D_ce to verify if
we/peer is AUTH capable") and b14878ccb7fa ("net: sctp: cache
auth_enable per endpoint"), this one is a bit of a different
kind.
Giving a bit more background on why SCTP authentication is
needed can be found in RFC4895:
SCTP uses 32-bit verification tags to protect itself against
blind attackers. These values are not changed during the
lifetime of an SCTP association.
Looking at new SCTP extensions, there is the need to have a
method of proving that an SCTP chunk(s) was really sent by
the original peer that started the association and not by a
malicious attacker.
To cause this bug, we're triggering an INIT collision between
peers; normal SCTP handshake where both sides intent to
authenticate packets contains RANDOM; CHUNKS; HMAC-ALGO
parameters that are being negotiated among peers:
---------- INIT[RANDOM; CHUNKS; HMAC-ALGO] ---------->
<------- INIT-ACK[RANDOM; CHUNKS; HMAC-ALGO] ---------
-------------------- COOKIE-ECHO -------------------->
<-------------------- COOKIE-ACK ---------------------
RFC4895 says that each endpoint therefore knows its own random
number and the peer's random number *after* the association
has been established. The local and peer's random number along
with the shared key are then part of the secret used for
calculating the HMAC in the AUTH chunk.
Now, in our scenario, we have 2 threads with 1 non-blocking
SEQ_PACKET socket each, setting up common shared SCTP_AUTH_KEY
and SCTP_AUTH_ACTIVE_KEY properly, and each of them calling
sctp_bindx(3), listen(2) and connect(2) against each other,
thus the handshake looks similar to this, e.g.:
---------- INIT[RANDOM; CHUNKS; HMAC-ALGO] ---------->
<------- INIT-ACK[RANDOM; CHUNKS; HMAC-ALGO] ---------
<--------- INIT[RANDOM; CHUNKS; HMAC-ALGO] -----------
-------- INIT-ACK[RANDOM; CHUNKS; HMAC-ALGO] -------->
...
Since such collisions can also happen with verification tags,
the RFC4895 for AUTH rather vaguely says under section 6.1:
In case of INIT collision, the rules governing the handling
of this Random Number follow the same pattern as those for
the Verification Tag, as explained in Section 5.2.4 of
RFC 2960 [5]. Therefore, each endpoint knows its own Random
Number and the peer's Random Number after the association
has been established.
In RFC2960, section 5.2.4, we're eventually hitting Action B:
B) In this case, both sides may be attempting to start an
association at about the same time but the peer endpoint
started its INIT after responding to the local endpoint's
INIT. Thus it may have picked a new Verification Tag not
being aware of the previous Tag it had sent this endpoint.
The endpoint should stay in or enter the ESTABLISHED
state but it MUST update its peer's Verification Tag from
the State Cookie, stop any init or cookie timers that may
running and send a COOKIE ACK.
In other words, the handling of the Random parameter is the
same as behavior for the Verification Tag as described in
Action B of section 5.2.4.
Looking at the code, we exactly hit the sctp_sf_do_dupcook_b()
case which triggers an SCTP_CMD_UPDATE_ASSOC command to the
side effect interpreter, and in fact it properly copies over
peer_{random, hmacs, chunks} parameters from the newly created
association to update the existing one.
Also, the old asoc_shared_key is being released and based on
the new params, sctp_auth_asoc_init_active_key() updated.
However, the issue observed in this case is that the previous
asoc->peer.auth_capable was 0, and has *not* been updated, so
that instead of creating a new secret, we're doing an early
return from the function sctp_auth_asoc_init_active_key()
leaving asoc->asoc_shared_key as NULL. However, we now have to
authenticate chunks from the updated chunk list (e.g. COOKIE-ACK).
That in fact causes the server side when responding with ...
<------------------ AUTH; COOKIE-ACK -----------------
... to trigger a NULL pointer dereference, since in
sctp_packet_transmit(), it discovers that an AUTH chunk is
being queued for xmit, and thus it calls sctp_auth_calculate_hmac().
Since the asoc->active_key_id is still inherited from the
endpoint, and the same as encoded into the chunk, it uses
asoc->asoc_shared_key, which is still NULL, as an asoc_key
and dereferences it in ...
crypto_hash_setkey(desc.tfm, &asoc_key->data[0], asoc_key->len)
... causing an oops. All this happens because sctp_make_cookie_ack()
called with the *new* association has the peer.auth_capable=1
and therefore marks the chunk with auth=1 after checking
sctp_auth_send_cid(), but it is *actually* sent later on over
the then *updated* association's transport that didn't initialize
its shared key due to peer.auth_capable=0. Since control chunks
in that case are not sent by the temporary association which
are scheduled for deletion, they are issued for xmit via
SCTP_CMD_REPLY in the interpreter with the context of the
*updated* association. peer.auth_capable was 0 in the updated
association (which went from COOKIE_WAIT into ESTABLISHED state),
since all previous processing that performed sctp_process_init()
was being done on temporary associations, that we eventually
throw away each time.
The correct fix is to update to the new peer.auth_capable
value as well in the collision case via sctp_assoc_update(),
so that in case the collision migrated from 0 -> 1,
sctp_auth_asoc_init_active_key() can properly recalculate
the secret. This therefore fixes the observed server panic.

Previously we would do a regulator get against the main Arizona device
to obtain the MICVDD regulator. Arizona is an MFD device and normally
MICVDD will be supplied by one of its children (the arizona-micsupp
regulator). As devres destruction for the MFD device will run after all
its children have been destroyed, the regulator will be destroyed before
devres calls regulator_put. This causes a warning from both the
destruction of the child node, as the regulator is still open, and from
the put of the regulator as the regulator device has already been
destroyed.
A simple fix here is to get the regulator against the extcon device
itself such that devres runs when the child is destroyed. This has the
additional benefit that if for some reason the extcon driver is unloaded
the regulator reference won't hang around until the MFD is unloaded.

We introduced unified FW status function in patch
mei: add per device configuration (lkml.org/lkml/2014/5/12/607)
This change made hw_ops functions unused and obsolete
therefore we remove these functions from source code.

This patch introduces the use of managed interfaces like devm_kzalloc,
devm_regulator_bulk_get and does away with the functions to free the
allocated memory in the probe and remove functions. Also, some labels
are removed and renamed to preserve the ordering.

Move the proc entry controlling the boottotool flag to procfs. The field
appears in /sys/devices/platform/visorchipset/install/boottotool.
The boottotool flag controls s-Par behavior on the next boot of this guest.
Setting the flag will cause the guest to boot from the utility and installation
image, which will use the value in the toolaction field to determine what
operation is being requested.

Move the proc entry for controlling the toolaction field to sysfs. The field
appears in /sys/devices/platform/visorchipset/install/toolaction.
This field is used to tell s-Par which type of recovery tool action to perform
on the next guest boot-up. The meaning of the value is dependent on the type
of installation software used to commission the guest.

`ni6527_reset()` is called to reset various registers when the device is
being initialized or deinitialized. The edge detection interrupt is
disabled by this function, but the rising and falling edge detection
registers are currently left alone. Call `ni6527_set_edge_detection()`
to set them to a known, disabled state.

The "edge detection interrupt" subdevice supports the
`INSN_CONFIG_CHANGE_NOTIFY` comedi instruction which is only supported
by one other driver. The `INSN_CONFIG_DIGITAL_TRIG` comedi instruction
is more flexible as it supports both edge and level detection, but is
not currently supported by this driver.
Add partial support for `INSN_CONFIG_DIGITAL_TRIG`, but only for edge
detection. Make use of the `ni6527_set_edge_detection()` used for
`INSN_CONFIG_CHANGE_NOTIFY`, but add a parameter holding a mask of the
rising and falling edges to be updated and preserve the unmasked edges
when updating.

This driver currently inverts the outputs for the DO (digital output)
subdevice for some of the boards it supports, indicated by the
`invert_outputs` member in the board-specific data being initialized to
1. It seems this driver shouldn't really be inverting outputs for these
boards at all, but has done so since the driver was first written back
in October 2006. I've had confirmation that for the PCI-6515 at least,
the output voltage levels are opposite to the values set by the user
program.
The driver by Jon Grierson originally supported only PCI-6514 and
PXI-6514 (and was originally called "ni_6514"). The driver was based on
"ni_6527", which is where the inversion of outputs appears to have come
from. Over a period of a few days, the driver was enhanced by Frank
Mori Hess to support other boards. Some of these plainly didn't require
inverted outputs and some guesswork was used to decide which boards
should have inverted outputs. Some of the boards in question are
described in the manual as having "Sink Outputs" and others are
described as having "Source Outputs", but this does not correspond in
any way with which boards are marked as having inverted outputs, so the
criterion that Frank used is a bit of a mystery!
Change the driver so it doesn't invert the outputs of these by boards by
default, but add a module parameter, "legacy_invert_outputs", that can
be set to 'true' to restore the old behaviour. Also rename the
`invert_outputs` member of `struct ni_65xx_board` to `legacy_invert`.
