While MXS_DCP_CONTROL0_OTP_KEY is set, the CRYPTO_KEY (DCP_PAES_KEY_OTP)
is used even if the UNIQUE_KEY (DCP_PAES_KEY_UNIQUE) is selected. This
is not clearly documented, but this implementation is consistent with
NXP's downstream kernel fork and optee_os.

Modifying the crypto_request turns out to be not the right way to handle
the stale value issue with the IV. Though the IV is not used for AES ECB,
it eventually get used in algorithms like LRW in the next step after
AES ECB encryption/decryption. Setting req->iv to NULL breaks the
implementation of such algorithms. Hence modify only the local reqctx
to check for IV.

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).
To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.
Hence, with this patch, this is what will happen:
echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync
There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.
True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

The commit 320406cb60 ("crypto: inside-secure - Replace generic aes
with libaes") replaced crypto_alloc_cipher() with kmalloc(), but did not
modify the handling of the return value. When kmalloc() returns NULL,
PTR_ERR_OR_ZERO(NULL) returns 0, but in fact, the memory allocation has
failed, and -ENOMEM should be returned.

The while loop breaks in the first run because of incorrect
if condition. It also causes the statements after the if to
appear dead.
Fix this by changing the condition from if(timeout--) to
if(!timeout--).

[ Upstream commit 7019935990 ]
Resetting the service arbiter config can cause potential issues
related to response ordering and ring flow control check in the
event of AER or device hang. This is because it results in changing
the default response ring size from 32 bytes to 16 bytes. The service
arbiter config reset also disables response ring flow control check.
Thus, by removing this reset we can prevent the service arbiter from
being configured inappropriately, which leads to undesired device
behaviour in the event of errors.

[ Upstream commit 23717055a7 ]
The debugfs functions are guaranteed to return a valid error code
instead of NULL upon failure. Consequently, the driver can directly
propagate any error returned without additional checks.
Remove the unnecessary `if` statement after debugfs_create_dir(). If
this function fails, the error code is stored in accel_dev->debugfs_dir
and utilized in subsequent debugfs calls.
Additionally, since accel_dev->debugfs_dir is assured to be non-NULL,
remove the superfluous NULL pointer checks within the adf_dbgfs_add()
and adf_dbgfs_rm().
