[PATCH v8 00/16] crypto: caam - Add i.MX8MQ support

[Andrey Smirnov <andrew.smirnov@gmail.com>]

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
    commits that this sereis is based on
