The qcom-rng driver supports both ACPI and device tree based systems.
Let's rename all instances of *of_data to *match_data so that it's
not implied that this driver only supports device tree-based systems.

The qcom-rng driver supports both ACPI and device tree-based systems.
ACPI support was broken when the hw_random interface support was added.
Let's go ahead and fix this by adding the appropriate driver data to the
ACPI match table, and change the of_device_get_match_data() call to
device_get_match_data() so that it will also work on ACPI-based systems.
This fix was boot tested on a Qualcomm Amberwing server (ACPI based) and
on a Qualcomm SA8775p Automotive Development Board (DT based). I also
verified that qcom-rng shows up in /proc/crypto on both systems.

Use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of

is known at compile-time, and refactor the rest of the code,
accordingly.

for_each_available_child_of_node() can help to iterate through the
device_node, and we don't need to use while loop. Besides, the purpose
of the while loop is to find a device_node which fits the condition
"child_req_np == ref_np", we can just read the property of "child_np"
directly in for_each_available_child_of_node(). No functional change
with such conversion.

The Policer registers in the ALE register space are just shadow registers
and use an index field in the policer table control register to read/write
to the actual Polier registers.
Add helper functions to Read and Write to Policer registers.
Also add a helper function to set the thread value to classifier/policer
mapping. Any packet that first matches the classifier will be sent to the
thread (flow) that is set in the classifier to thread mapping table.
If not set then it goes to the default flow.
Default behaviour is to have 8 classifiers to map 8 DSCP/PCP
priorities to N receive threads (flows). N depends on number of
RX channels enabled for the port.
As per the standard [1] User prioritie 1 (Background) and 2 (Spare) have
lower priority than the user priority 0 (default). User priority 1 being
of the lowest priority.

am65-cpsw can support up to 8 queues at Rx.
Use a macro AM65_CPSW_MAX_RX_QUEUES to indicate that.
As there is only one DMA channel for RX traffic, the
8 queues come as 8 flows in that channel.
By default, we will start with 1 flow as defined by the
macro AM65_CPSW_DEFAULT_RX_CHN_FLOWS.
User can change the number of flows by ethtool like so
'ethtool -L ethx rx <N>'
All traffic will still come on flow 0. To get traffic on
different flows the Classifiers will need to be set up.

The TPM event log table is a Linux specific construct, where the data
produced by the GetEventLog() boot service is cached in memory, and
passed on to the OS using an EFI configuration table.
The use of EFI_LOADER_DATA here results in the region being left
unreserved in the E820 memory map constructed by the EFI stub, and this
is the memory description that is passed on to the incoming kernel by
kexec, which is therefore unaware that the region should be reserved.
Even though the utility of the TPM2 event log after a kexec is
questionable, any corruption might send the parsing code off into the
weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY
instead, which is always treated as reserved by the E820 conversion
logic.

If the busy indicator is set, all other fields in CCI should be
clear according to the spec. However, some UCSI implementations do
not follow this rule and report bogus data in CCI along with the
busy indicator. Ignore the contents of CCI if the busy indicator is
set.
If a command timeout is hit it is possible that the EVENT_PENDING
bit is cleared while connector work is still scheduled which can
cause the EVENT_PENDING bit to go out of sync with scheduled connector
work. Check and set the EVENT_PENDING bit on entry to
ucsi_handle_connector_change() to fix this.
Finally, check UCSI_CCI_BUSY before the return code of ->sync_control.
This ensures that the command is cancelled even if ->sync_control
returns an error (most likely -ETIMEDOUT).

The __get_dwc3_maximum_speed() function returns an enum type which, in
this context here, is basically unsigned int. On error cases, it's
supposed to return USB_SPEED_UNKNOWN, but it was accidentally changed to
return negative error codes in commit f93e96c544ca ("usb: dwc3: rtk: use
scoped device node handling to simplify error paths").
There is only one caller and because of the way that the types work out,
returning negative error codes is not a problem. They will be treated
as greater than USB_SPEED_HIGH and ignored as invalid. So this patch
does not affect run time behavior, it's just a clean up.

Improve commit fc88bb116179 ("usb: roles: add lockdep class key to struct
usb_role_switch") as follows:
* Move the lock class key declaration just above the mutex declaration such
that the declaration order of these objects matches their initialization
order.
* Destroy the mutex and lock class key just before these objects are
freed. This makes it easier to verify that the destruction calls happen
after the last use of these objects.
* Instead of switching the mutex key to the dynamic lock class key after
initialization of the mutex has completed, initialize the mutex with the
dynamic lock class key.

disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.

If the FW crashes, L2 driver gets notified and it notifies
the RoCE driver. Currently driver doesn't re-initialize the
device. Add support for re-initialize the RoCE device.
RoCE device is removed and re-attached in the ulp_stop and
ulp_start respectively. The recovery logic expects the RoCE
driver to be registered with L2 driver while its being removed.
So the driver avoids unregistering with L2 driver in the
recovery path.

Adding and removing device need to be handled from multiple contexts
when Firmware error recovery is supported. So group all the add and remove
operations to add_device and remove_device function.

While registering with the L2 for ULP operations, use the
aux device pointer as the handle. Aux device has
the data bnxt_re_en_dev_info, which is used to
store required information for the bnxt_re_suspend
and bnxt_re_resume functions.

rdev will be destroyed and recreated during the FW error
recovery scenarios. So to keep the state, if any, use an
en_info structure which gets created/freed based on auxiliary
device initialization/de-initialization.
