crypto: starfive - Fix dev_err_probe return error

2023-12-15T09:52:53+00:00

Current dev_err_probe will return 0 instead of proper error code if
driver failed to get irq number. Fix the return code.

crypto: starfive - Pad adata with zeroes

2023-12-01T10:03:26+00:00

Aad requires padding with zeroes up to 15 bytes in some cases. This
patch increases the allocated buffer size for aad and prevents the
driver accessing uninitialized memory region.

v1->v2: Specify reason for alloc size change in descriptions.

crypto: starfive - RSA poll csr for done status

2023-11-24T10:13:56+00:00

Hardware could not clear irq status without resetting the entire module.
Driver receives irq immediately when mask bit is cleared causing
intermittent errors in RSA calculations. Switch to use csr polling for
done status instead.

crypto: starfive - Update driver dependencies

2023-11-24T10:13:56+00:00

Change AMBA_PL08X to required dependency as the hash ops depends on it
for data transfer.

crypto: jh7110 - Correct deferred probe return

2023-11-17T11:16:29+00:00

This fixes list_add corruption error when the driver is returned
with -EPROBE_DEFER. It is also required to roll back the previous
probe sequences in case of deferred_probe. So, this removes
'err_probe_defer" goto label and just use err_dma_init instead.

crypto: starfive - remove unnecessary alignmask for ahashes

2023-10-27T10:04:29+00:00

The crypto API's support for alignmasks for ahash algorithms is nearly
useless, as its only effect is to cause the API to align the key and
result buffers.  The drivers that happen to be specifying an alignmask
for ahash rarely actually need it.  When they do, it's easily fixable,
especially considering that these buffers cannot be used for DMA.

In preparation for removing alignmask support from ahash, this patch
makes the starfive driver no longer use it.  This driver did actually
rely on it, but only for storing to the result buffer using int stores
in starfive_hash_copy_hash().  This patch makes
starfive_hash_copy_hash() use put_unaligned() instead.  (It really
should use a specific endianness, but that's an existing bug.)

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
