[PATCH v6 00/14] crypto: caam - Add i.MX8MQ support

From: Andrey Smirnov
Date: Wed Jul 17 2019 - 11:25:15 EST


Everyone:

Picking up where Chris left off (I chatted with him privately
beforehead), this series adds support for i.MX8MQ to CAAM driver. Just
like [v1], this series is i.MX8MQ only.

Feedback is welcome!
Thanks,
Andrey Smirnov

Changes since [v5]:

- Hunk replacing sizeof(*jrp->inpring) to SIZEOF_JR_INPENTRY in
"crypto: caam - don't hardcode inpentry size", lost in [v5], is
back

- Collected Tested-by from Iuliana

Changes since [v4]:

- Fixed missing sentinel element in "crypto: caam - simplfy clock
initialization"

- Squashed all of the devers related patches into a single one and
converted IRQ allocation to use devres while at it

- Added "crypto: caam - request JR IRQ as the last step" as
discussed

Changes since [v3]:

- Patchset changed to select DMA size at runtime in order to enable
support for both i.MX8MQ and Layerscape at the same time. I only
tested the patches on i.MX6,7 and 8MQ, since I don't have access
to any of the Layerscape HW. Any help in that regard would be
appareciated.

- Bulk clocks and their number are now stored as a part of struct
caam_drv_private to simplify allocation and cleanup code (no
special context needed)

- Renamed 'soc_attr' -> 'imx_soc_match' for clarity

Changes since [v2]:

- Dropped "crypto: caam - do not initialise clocks on the i.MX8" and
replaced it with "crypto: caam - simplfy clock initialization" and
"crypto: caam - add clock entry for i.MX8MQ"


Changes since [v1]

- Series reworked to continue using register based interface for
queueing RNG initialization job, dropping "crypto: caam - use job
ring for RNG instantiation instead of DECO"

- Added a patch to share DMA mask selection code

- Added missing Signed-off-by for authors of original NXP tree
commits that this sereis is based on
