QCA99X0 uses radio specific board names based on chip id and
board id combinations. We get these IDs from the target using BMI after otp.bin
has been started.
This patch reorders the call to the function ath10k_core_fetch_board_file
so that we have OTP binary before requesting for boardid-chipid. We get this
OTP data after parsing firmware-N.bin.

QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.
ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:
/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.
This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:
bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x
This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

This code was a bit sloppy, would produce a lot of copy-and-paste, and
did not always provide a sensible interface:
* It didn't validate the length for LOCK and the offset for UNLOCK, so
we were essentially discarding half of the user-supplied data and
assuming what they wanted to lock/unlock
* It didn't do very good error checking
* It didn't make use of the fact that this operation works on
power-of-two dimensions
So, rewrite this to do proper bit arithmetic rather than a bunch of
hard-coded condition tables. Now we have:
* More comments on how this was derived
* Notes on what is (and isn't) supported
* A more exendible function, so we could add support for other
protection ranges
* More accurate locking - e.g., suppose the top quadrant is locked (75%
to 100%); then in the following cases, case (a) will succeed but (b)
will not (return -EINVAL):
(a) user requests lock 3rd quadrant (50% to 75%)
(b) user requests lock 3rd quadrant, minus a few blocks (e.g., 50%
to 73%)
Case (b) *should* fail, since we'd have to lock blocks that weren't
requested. But the old implementation didn't know the difference and
would lock the entire second half (50% to 100%)
This refactoring work will also help enable the addition of
mtd_is_locked() support and potentially the support of bottom boot
protection (TB=1).

Commit ba2bbfbf63 (PM / Domains: Remove intermediate states from the
power off sequence) changed the power off sequence in genpd. That also
required some updates regarding the validation of latency constraints in
the genpd governor. Unfortunate that wasn't covered, so let's fix this.
From a runtime PM and latency point of view, we need to consider the worst
case scenario while validating latency constraints. That's typically when
a call to pm_runtime_get_sync() needs to wait for a ongoing runtime
suspend operation to be carried out, as it then also needs to wait for the
device to be runtime resumed again.
The above mentioned commit made the genpd governor's ->stop_ok() callback
responsible of validating genpd's device's runtime suspend/resume latency.
In other words, the constraint needs to be validated towards the relevant
latencies present in genpd's ->runtime_suspend|resume() callbacks.
Earlier, that included latencies from the ->stop|start() callbacks, but as
->save|restore_state() are now also being invoked from genpd's
->runtime_suspend|resume() and to comply with the worst case scenario,
let's take also those latencies into account.

If the upcoming system suspend is not going to be handled by the
platform firmware, like in the suspend-to-idle case, it is not
necessary to reset the controller in i8042_pm_suspend(), so avoid
doing that.
Moreover, if the system resume currently in progress has not been
started by the platform firmware, like in the suspend-to-idle case,
i8042_controller_resume() need not be called by i8042_pm_resume(),
so avoid doing that too in that case.
Additionally, try to catch the event that woke up the system by
calling the interrupt handler early during system resume if it has
not been started by the platform firmware.

There is a concern that if the platform firmware was involved in
the system resume that's being completed, some devices might have
been reset by it and if those devices had the power.direct_complete
flag set during the preceding suspend transition, they may stay
in a reset-power-on state indefinitely (until they are runtime-resumed
and then suspended again). That may not be a big deal from the
individual device's perspective, but if the system is an SoC, it may
be prevented from entering deep SoC-wide low-power states on idle
because of that.
The devices that are most likely to be affected by this issue are
PCI devices and ACPI-enumerated devices using the general ACPI PM
domain, so to prevent it from happening for those devices, force a
runtime resume for them if they have their power.direct_complete
flags set and the platform firmware was involved in the resume
transition currently in progress.

There are quite a few cases in which device drivers, bus types or
even the PM core itself may benefit from knowing whether or not
the platform firmware will be involved in the upcoming system power
transition (during system suspend) or whether or not it was involved
in it (during system resume).
For this reason, introduce global system suspend flags that can be
used by the platform code to expose that information for the benefit
of the other parts of the kernel and make the ACPI core set them
as appropriate.
Users of the new flags will be added later.

The pm_request_idle() in pm_generic_complete() is pointless as it is
called with the runtime PM usage counter different from zero (bumped
up by the core during the prepare phase of system suspend) and the
core calls pm_runtime_put() for all devices after executing their
complete callbacks, so drop it.
This allows the PCI PM layer to use pm_generic_complete() too.

Currently firmware file name is included in the DTS. This is not scalable
as user has to change the DTS if they need upgrade to a new firmware.
Instead, add the firmware file name in the driver itself. As long as there
is no API change, new firmware upgrade is easy and require no driver
change. User is expected to copy the firmware image to the file system
and add a sym link to the new firmware for doing an upgrade. Driver add
a array of firmware file names to search for the available firmware blobs.
This scheme also prepare the driver for future changes to API if ever
happens. In such case it is assumed that driver needs to change to
accommodate the new firmware and new firmware file name will get added to
the array.

md-cluster: A better way for METADATA_UPDATED processing
The processing of METADATA_UPDATED message is too simple and prone to
errors. Besides, it would not update the internal data structures as
required.
This set of patches reads the superblock from one of the device of the MD
and checks for changes in the in-memory data structures. If there is a change,
it performs the necessary actions to keep the internal data structures
as it would be in the primary node.
An example is if a devices turns faulty. The algorithm is:
1. The initiator node marks the device as faulty and updates the superblock
2. The initiator node sends METADATA_UPDATED with an advisory device number to the rest of the nodes.
3. The receiving node on receiving the METADATA_UPDATED message
3.1 Reads the superblock
3.2 Detects a device has failed by comparing with memory structure
3.3 Calls the necessary functions to record the failure and get the device out of the active array.
3.4 Acknowledges the message.
The patch series also fixes adding the disk which was impacted because of
the changes.
Patches can also be found at
https://github.com/goldwynr/linux branch md-next
Changes since V2:
- Fix status synchrnoization after --add and --re-add operations
- Included Guoqing's patches on endian correctness, zeroing cmsg etc
- Restructure add_new_disk() and cancel()
The ->read_xxx() methods are all passed the page number the NAND controller
is supposed to read, but ->write_xxx() do not have such a parameter.
This is a problem if we want to properly implement data
scrambling/randomization in order to mitigate MLC sensibility to repeated
pattern: to prevent bitflips in adjacent pages in the same block we need
to avoid repeating the same pattern at the same offset in those pages,
hence the randomizer/scrambler engine need to be passed the page value
in order to adapt its seed accordingly.
Moreover, adding the page parameter to the ->write_xxx() methods add some
consistency to the current API.
