The AXG Analog MIPI-DSI PHY also provides functions to the PCIe PHY,
thus we need to have inclusive support for both interfaces at runtime.
This fixes the regmap get from parent node, removes cell param
to select a mode and implement runtime configuration & power on/off
for both functions since they are not exclusive.

The parallel port restore operation currently defers writes
to a tasklet, if it sees a locked disconnect mutex. The
driver goes to a lot of trouble to ensure writes happen
in a non-blocking context, but things can be greatly
simplified if it's done in regular process context and
this is not a system performance critical path. As such,
instead of doing the state restore writes in softirq context,
use a workqueue and just do regular synchronous writes.
In addition to the cleanup, this also imposes less on the
overall system as tasklets have been deprecated because
of it's softirq implications, potentially blocking a higher
priority task from running.

We recently introduced a 1 GB sized ZONE_DMA to cater for platforms
incorporating masters that can address less than 32 bits of DMA, in
particular the Raspberry Pi 4, which has 4 or 8 GB of DRAM, but has
peripherals that can only address up to 1 GB (and its PCIe host
bridge can only access the bottom 3 GB)
Instructing the DMA layer about these limitations is straight-forward,
even though we had to fix some issues regarding memory limits set in
the IORT for named components, and regarding the handling of ACPI _DMA
methods. However, the DMA layer also needs to be able to allocate
memory that is guaranteed to meet those DMA constraints, for bounce
buffering as well as allocating the backing for consistent mappings.
This is why the 1 GB ZONE_DMA was introduced recently. Unfortunately,
it turns out the having a 1 GB ZONE_DMA as well as a ZONE_DMA32 causes
problems with kdump, and potentially in other places where allocations
cannot cross zone boundaries. Therefore, we should avoid having two
separate DMA zones when possible.
So let's do an early scan of the IORT, and only create the ZONE_DMA
if we encounter any devices that need it. This puts the burden on
the firmware to describe such limitations in the IORT, which may be
redundant (and less precise) if _DMA methods are also being provided.
However, it should be noted that this situation is highly unusual for
arm64 ACPI machines. Also, the DMA subsystem still gives precedence to
the _DMA method if implemented, and so we will not lose the ability to
perform streaming DMA outside the ZONE_DMA if the _DMA method permits
it.

ISO 11898-1 Chapter 8.4.2.3 defines a 4 bit data length code (DLC) table which
maps the DLC to the payload length of the CAN frame in bytes:
DLC -> payload length
0 .. 8 -> 0 .. 8
9 .. 15 -> 8
Although the DLC values 8 .. 15 in Classical CAN always result in a payload
length of 8 bytes these DLC values are transparently transmitted on the CAN
bus. As the struct can_frame only provides a 'len' element (formerly 'can_dlc')
which contains the plain payload length ( 0 .. 8 ) of the CAN frame, the raw
DLC is not visible to the application programmer, e.g. for testing use-cases.
To access the raw DLC values 9 .. 15 the len8_dlc element is introduced, which
is only valid when the payload length 'len' is 8 and the DLC is greater than 8.
The len8_dlc element is filled by the CAN interface driver and used for CAN
frame creation by the CAN driver when the CAN_CTRLMODE_CC_LEN8_DLC flag is
supported by the driver and enabled via netlink configuration interface.

Bspec refers to the ports as DDIA, DDIB, DDI USBC1 and DDI USBC2
(besides the DDIA, DDIB, DDIC, DDID), but the previous naming is the
most unambiguous one. This means that for any register on Display Engine
we should use the index of A, B, D and E. However in some places this is
not true:
- VBT: uses C and D and have to be mapped to D/E
- IO/Combo: uses C and D, but we already differentiate those when
we created the phy vs port distinction.
This additional mapping for VBT and phy are already covered in previous
patches, so now we can initialize all the DDIs as A, B, D and E.

====================
devlink: move common flash_update calls to core
This series moves a couple common pieces done by all drivers of the
->flash_update interface into devlink.c flash update handler. Specifically,
the core code will now request_firmware and
devlink_flash_update_(begin|end)_notify.
This cleanup is intended to simplify driver implementations so that they
have less work to do and are less capable of doing the "wrong" thing.
For request_firmware, this simplification is done as it is not expected that
drivers would do anything else. It also standardizes all drivers so that
they use the same interface (request_firmware, as opposed to
request_firmware_direct), and allows reporting the netlink extended ack with
the file name attribute.
For status notification, this change prevents drivers from sending a status
message without properly sending the status end notification. The current
userspace implementation of devlink relies on this end notification to
properly close the flash update channel. Without this, the flash update
process may hang indefinitely. By moving the begin and end calls into the
core code, it is no longer possible for a driver author to get this wrong.
Changes since v3
* picked up acked-by and reviewed-by comments
* fixed the ionic driver to leave the print statement in place
For the original patch that moved request_firmware, see [1]. For the v2 see
[2]. For further discussion of the issues with devlink flash status see [3].

When performing a flash update via devlink, device drivers may inform
user space of status updates via
devlink_flash_update_(begin|end|timeout|status)_notify functions.
It is expected that drivers do not send any status notifications unless
they send a begin and end message. If a driver sends a status
notification without sending the appropriate end notification upon
finishing (regardless of success or failure), the current implementation
of the devlink userspace program can get stuck endlessly waiting for the
end notification that will never come.
The current ice driver implementation may send such a status message
without the appropriate end notification in rare cases.
Fixing the ice driver is relatively simple: we just need to send the
begin_notify at the start of the function and always send an end_notify
no matter how the function exits.
Rather than assuming driver authors will always get this right in the
future, lets just fix the API so that it is not possible to get wrong.
Make devlink_flash_update_begin_notify and
devlink_flash_update_end_notify static, and call them in devlink.c core
code. Always send the begin_notify just before calling the driver's
flash_update routine. Always send the end_notify just after the routine
returns regardless of success or failure.
Doing this makes the status notification easier to use from the driver,
as it no longer needs to worry about catching failures and cleaning up
by calling devlink_flash_update_end_notify. It is now no longer possible
to do the wrong thing in this regard. We also save a couple of lines of
code in each driver.

All drivers which implement the devlink flash update support, with the
exception of netdevsim, use either request_firmware or
request_firmware_direct to locate the firmware file. Rather than having
each driver do this separately as part of its .flash_update
implementation, perform the request_firmware within net/core/devlink.c
Replace the file_name parameter in the struct devlink_flash_update_params
with a pointer to the fw object.
Use request_firmware rather than request_firmware_direct. Although most
Linux distributions today do not have the fallback mechanism
implemented, only about half the drivers used the _direct request, as
compared to the generic request_firmware. In the event that
a distribution does support the fallback mechanism, the devlink flash
update ought to be able to use it to provide the firmware contents. For
distributions which do not support the fallback userspace mechanism,
there should be essentially no difference between request_firmware and
request_firmware_direct.

This patch fixes the following smatch warnings:
drivers/crypto/allwinner/sun8i-ce/sun8i-ce-hash.c:412
sun8i_ce_hash_run() warn: possible memory leak of 'result'
Note: "buf" is leaked as well.
Furthermore, in case of ENOMEM, crypto_finalize_hash_request() was not
called which was an error.
Fixes: 56f6d5aee8 ("crypto: sun8i-ce - support hash algorithms")

Add an hook to initialize the vector routing table with the default
values before MSIx is enabled.
The new function set_msix_rttable() is called only if present in the
struct adf_hw_device_data of the device. This is to allow for QAT
devices that do not support that functionality.
