Subject[PATCH v4 00/16] crypto: caam - Add i.MX8MQ support

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!
Andrey Smirnov

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

- 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


Andrey Smirnov (16):
crypto: caam - move DMA mask selection into a function
crypto: caam - simplfy clock initialization
crypto: caam - move tasklet_init() call down
crypto: caam - use deveres to allocate 'entinfo'
crypto: caam - use devres to allocate 'outring'
crypto: caam - use devres to allocate 'inpring'
crytpo: caam - make use of iowrite64*_hi_lo in wr_reg64
crypto: caam - use ioread64*_hi_lo in rd_reg64
crypto: caam - drop 64-bit only wr/rd_reg64()
crypto: caam - make CAAM_PTR_SZ dynamic
crypto: caam - move cpu_to_caam_dma() selection to runtime
crypto: caam - drop explicit usage of struct jr_outentry
crypto: caam - don't hardcode inpentry size
crypto: caam - force DMA address to 32-bit on 64-bit i.MX SoCs
crypto: caam - always select job ring via RSR on i.MX8MQ
crypto: caam - add clock entry for i.MX8MQ
