The i.MX8M Mini uses the same crypto engine as the i.MX8MQ, but
the driver is restricting the check to just the i.MX8MQ.
This patch expands the check for either i.MX8MQ or i.MX8MM.

In order to access IP block's registers we need to enable appropriate
clocks first, otherwise we are risking hanging the CPU.
The problem becomes very apparent when trying to use CAAM driver built
as a kernel module. In that case caam_probe() gets called after
clk_disable_unused() which means all of the necessary clocks are
guaranteed to be disabled.
Coincidentally, this change also fixes iomap leak introduced by early

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

The way Job Ring platform devices are created and released does not
allow for multiple create-release cycles.
JR0 Platform device creation error
JR0 Platform device creation error
caam 2100000.caam: no queues configured, terminating
caam: probe of 2100000.caam failed with error -12
The reason is that platform devices are created for each job ring:
for_each_available_child_of_node(nprop, np)
if (of_device_is_compatible(np, "fsl,sec-v4.0-job-ring") ||
of_device_is_compatible(np, "fsl,sec4.0-job-ring")) {
ctrlpriv->jrpdev[ring] =
of_platform_device_create(np, NULL, dev);
which sets OF_POPULATED on the device node, but then it cleans these up:
/* Remove platform devices for JobRs */
for (ring = 0; ring < ctrlpriv->total_jobrs; ring++) {
if (ctrlpriv->jrpdev[ring])
of_device_unregister(ctrlpriv->jrpdev[ring]);
}
which leaves OF_POPULATED set.
Use of_platform_populate / of_platform_depopulate instead.
This allows for a bit of driver clean-up, jrpdev is no longer needed.
Logic changes a bit too:
-exit in case of_platform_populate fails, since currently even QI backend
depends on JR; true, we no longer support the case when "some" of the JR
DT nodes are incorrect
-when cleaning up, caam_remove() would also depopulate RTIC in case
it would have been populated somewhere else - not the case for now

CAAM engine supports two interfaces for crypto job submission:
-job ring interface - already existing caam/jr driver
-Queue Interface (QI) - caam/qi driver added in current patch
QI is present in CAAM engines found on DPAA platforms.
QI gets its I/O (frame descriptors) from QMan (Queue Manager) queues.
This patch adds a platform device for accessing CAAM's queue interface.
The requests are submitted to CAAM using one frame queue per
cryptographic context. Each crypto context has one shared descriptor.
This shared descriptor is attached to frame queue associated with
corresponding driver context using context_a.
The driver hides the mechanics of FQ creation, initialisation from its
applications. Each cryptographic context needs to be associated with
driver context which houses the FQ to be used to transport the job to
CAAM. The driver provides API for:
(a) Context creation
(b) Job submission
(c) Context deletion
(d) Congestion indication - whether path to/from CAAM is congested
The driver supports affining its context to a particular CPU.
This means that any responses from CAAM for the context in question
would arrive at the given CPU. This helps in implementing one CPU
per packet round trip in IPsec application.
The driver processes CAAM responses under NAPI contexts.
NAPI contexts are instantiated only on cores with affined portals since
only cores having their own portal can receive responses from DQRR.
The responses from CAAM for all cryptographic contexts ride on a fixed
set of FQs. We use one response FQ per portal owning core. The response
FQ is configured in each core's and thus portal's dedicated channel.
This gives the flexibility to direct CAAM's responses for a crypto
context on a given core.

Start with a clean slate before dealing with bit 16 (pointer size)
of Master Configuration Register.
This fixes the case of AArch64 boot loader + AArch32 kernel, when
the boot loader might set MCFGR[PS] and kernel would fail to clear it.
