crypto: caam - disable some clock checks for iMX7ULP

2019-06-06T06:44:16+00:00

Disabled the check and set of 'mem' and 'emi_slow'
clocks, since these are not available for iMX7ULP.

crypto: caam/qi - fix address translations with IOMMU enabled

2019-05-23T06:01:04+00:00

When IOMMU is enabled, iova -> phys address translation should be
performed using iommu_ops, not dma_to_phys().

crypto: caam/qi - don't allocate an extra platform device

2019-05-23T06:01:04+00:00

Use the controller device for caam/qi instead of allocating
a new platform device.
This is needed as a preparation to add support for working behind an
SMMU. A platform device allocated using platform_device_register_full()
is not completely set up - most importantly .dma_configure()
is not called.

crypto: caam - convert top level drivers to libraries

2019-05-23T06:01:03+00:00

Currently we allow top level code, i.e. that which sits between the
low level (HW-specific) drivers and crypto API, to be built as several
drivers: caamalg, caamhash, caam_pkc, caamrng, caamalg_qi.

There is no advantage in this, more it interferes with adding support
for deferred probing (there are no corresponding devices and thus
no bus).

Convert these drivers and call init() / exit() manually at the right
time.
Move algorithms initialization at JR probe / remove time:
-the first probed JR registers the crypto algs
-the last removed JR unregisters the crypto algs

Note: caam_qi_init() is called before JR platform devices creation
(of_populate_bus()), such that QI interface is initialized when
the caam/qi algorithms are registered in the JR driver (by calling
caam_qi_algapi_init().

While here, fix the Kconfig entries under CRYPTO_DEV_FSL_CAAM_JR
to be aligned.

crypto: caam - fix typo in i.MX6 devices list for errata

2019-05-17T05:36:54+00:00

Fix a typo in the list of i.MX6 devices affected by an
issue wherein AXI bus transactions may not occur in
the correct order.

crypto: caam - limit AXI pipeline to a depth of 1

2019-03-28T05:55:34+00:00

Some i.MX6 devices (imx6D, imx6Q, imx6DL, imx6S, imx6DP and imx6DQ) have
an issue wherein AXI bus transactions may not occur in the correct order.
This isn't a problem running single descriptors, but can be if running
multiple concurrent descriptors. Reworking the CAAM driver to throttle
to single requests is impractical, so this patch limits the AXI pipeline
to a depth of one (from a default of 4) to preclude this situation from
occurring.
This patch applies to known affected platforms.

crypto: caam - no need to check return value of debugfs_create functions

2019-02-01T06:42:03+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

crypto: caam - move shared symbols in a common location

2019-01-11T06:16:55+00:00

There are several issues with symbols shared b/w:
-caam/jr and caam/qi drivers on one hand
-caam/qi2 driver on the other hand

Commit 52813ab24959 ("crypto: caam/qi2 - avoid double export") fixed
some of them, however compilation still fails for CRYPTO_DEV_FSL_CAAM=m
and CRYPTO_DEV_FSL_DPAA2_CAAM=y.

Another issue is related to dependency cycles reported by depmod when
CRYPTO_DEV_FSL_CAAM=n and CRYPTO_DEV_FSL_DPAA2_CAAM=m, as mentioned in
82c7b351be3f ("Revert "arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO"")

To fix all these, move the symbols shared by these drivers in a common
location. The only existing possibility is error.c file (note that naming
doesn't help and should probably change).

crypto: caam - add register map changes cf. Era 10

2018-11-16T06:11:03+00:00

Era 10 changes the register map.

The updates that affect the drivers:
-new version registers are added
-DBG_DBG[deco_state] field is moved to a new register -
DBG_EXEC[19:16] @ 8_0E3Ch.
