crypto: keembay - Move driver to drivers/crypto/intel/keembay

2023-04-06T08:35:17+00:00

With the growing number of Intel crypto drivers, it makes sense to
group them all into a single drivers/crypto/intel/ directory.

crypto: keembay - Drop if with an always false condition

2023-03-24T10:22:28+00:00

A platform device's remove callback is only ever called after the probe
callback returned success.

In the case of kmb_ocs_aes_remove() this means that kmb_ocs_aes_probe()
succeeded before and so platform_set_drvdata() was called with a
non-zero argument and platform_get_drvdata() returns non-NULL.

This prepares making remove callbacks return void.

crypto: keembay - Set DMA alignment explicitly

2022-12-09T10:45:00+00:00

This driver has been implicitly relying on kmalloc alignment
to be sufficient for DMA.  This may no longer be the case with
upcoming arm64 changes.

This patch changes it to explicitly request DMA alignment from
the Crypto API.

crypto: keembay-ocs - Drop obsolete dependency on COMPILE_TEST

2022-08-19T10:39:36+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

crypto: keembay-ocs-ecc - Drop if with an always false condition

2022-07-22T08:22:03+00:00

The remove callback is only called after probe completed successfully.
In this case platform_set_drvdata() was called with a non-NULL argument
and so ecc_dev is never NULL.

This is a preparation for making platform remove callbacks return void.

crypto: keembay - Make use of devm helper function devm_platform_ioremap_resource()

2022-04-29T05:44:57+00:00

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.Make the
code simpler without functional changes.

crypto: keembay-ocs-ecc - Fix error return code in kmb_ocs_ecc_probe()

2021-11-20T04:02:08+00:00

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.

crypto: keembay-ocs-ecc - Add Keem Bay OCS ECC Driver

2021-10-29T13:04:03+00:00

The Intel Keem Bay SoC can provide hardware acceleration of Elliptic
Curve Cryptography (ECC) by means of its Offload and Crypto Subsystem
(OCS).

Add the Keem Bay OCS ECC driver which leverages such hardware
capabilities to provide hardware-acceleration of ECDH-256 and ECDH-384.

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
