For better maintainability, try to concentrate all the common functions
that communicate with the f/w in firmware_if.c

The two remaining functions in this file belong to firmware_if.c,
as they communicate with the firmware.

Retrieving the clock from the f/w is done exactly the same in ALL our
ASICs. Therefore, no real justification for doing it as an
ASIC-specific function.
The only thing is we need to check if we are running on simulator,
which doesn't require ASIC-specific callback.

Now that clock gating is permanently disabled in GAUDI, no need for

Due to the need of SynapseAI to configure all TPC engines from a single

This patch fixes what seems to be copy paste error.
We will have a memory leak if the host-resident shadow is NULL (which

As part of handling of the multi-CS wait ioctl, hl_cs_poll_fences() is
called in a "while (true)" loop. This function can fail, but the
checking of its return value was missed.
Add this check and exit the loop in case of a failure.

If the state is not idle then resolve_prepare_src() should immediately
fail and no change to global state should happen. However, it
unconditionally overwrites the src_addr trying to build a temporary any
address.
For instance if the state is already RDMA_CM_LISTEN then this will corrupt
the src_addr and would cause the test in cma_cancel_operation():
if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev)
Which would manifest as this trace from syzkaller:
BUG: KASAN: use-after-free in __list_add_valid+0x93/0xa0 lib/list_debug.c:26

This is indicating that an rdma_id_private was destroyed without doing
cma_cancel_listens().
Instead of trying to re-use the src_addr memory to indirectly create an
any address derived from the dst build one explicitly on the stack and
bind to that as any other normal flow would do. rdma_bind_addr() will copy
it over the src_addr once it knows the state is valid.
This is similar to commit bc0bdc5afaa7 ("RDMA/cma: Do not change
route.addr.src_addr.ss_family")

During the hardware start sequence, do not overwrite the driver state
and do not proceed with the initialization sequence if the state
was changed while the driver was waiting for the start interrupt.
This can happen if the driver's removal/stop procedure was triggered
from the parent level while the driver is waiting for the start
interrupt. This may lead to stray the reset work or the timer
after driver were removed.

The family and device comparisons were using memcmp(), but this could
lead to Out-of-bounds reads when the length was larger than the
buffers being compared. Since these appear to always be NUL-terminated
strings, just use strcmp() instead.

dma_alloc_coherent() already clear the allocated memory, there is no need
to explicitly call memset().
This saves a few cycles and a few lines of code.

vmci_check_host_caps() doesn't return a bool but an int.
Fix the description accordingly.

w1_seq was failing due to several devices responding to the
CHAIN_DONE at the same time. Now properly selects the current
device in the chain with MATCH_ROM. Also acknowledgment was
read twice.

Extend Intel service layer driver to get the firmware version running at
FPGA device. Therefore FPGA manager driver, one of Intel service layer
driver's client, can decide whether to handle the newly added bitstream
authentication function based on the retrieved firmware version.

sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout.
Current timeout is simply too low. Since blowing fuses is a
very rare operation, so the risk associated with overestimating this
number is low.
Increase fuse blow timeout from 1ms to 10ms.

Delta TN48M switch has an onboard Lattice CPLD that is used as a GPIO
expander.
The CPLD provides 12 pins in total on the TN48M, but on more advanced
switch models it provides up to 192 pins, so the driver is extendable
to support more switches.

Delta TN48M switches have a Lattice CPLD that serves
multiple purposes including being a GPIO expander.
So, lets use the simple I2C MFD driver to provide the MFD core.
Also add a virtual symbol which pulls in the simple-mfd-i2c driver and
provide a common symbol on which the subdevice drivers can depend on.
