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 [v7]:
- Series rebase on latest cryptodev-2.6 (198429631a85)
- "crypto: caam - force DMA address to 32-bit on 64-bit i.MX SoCs"
converted to use CTPR and MCFGR to determine CAAM pointer width
and renamed to "crypto: caam - select DMA address size at runtime"
- Patch adding corresponding DT node added to the series
Changes since [v6]:
- Fixed build problems in "crypto: caam - make CAAM_PTR_SZ dynamic"
- Collected Reviewied-by from Horia
- "crypto: caam - force DMA address to 32-bit on 64-bit i.MX SoCs"
is changed to check 'caam_ptr_sz' instead of using 'caam_imx'
- Incorporated feedback for "crypto: caam - request JR IRQ as the
last step" and "crypto: caam - simplfy clock initialization"
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
