CDM block comes with its own set of registers and operations
which can be done. In-line with other hardware sub-blocks, this
change adds the dpu_hw_cdm abstraction for the CDM block.
changes in v2:
- replace bit magic with relevant defines
- use drmm_kzalloc instead of kzalloc/free
Even though there is usually only one CDM block, it can be
used by either HDMI, DisplayPort OR Writeback interfaces.
Hence its allocation needs to be tracked properly by the

These are the patches from the from the prior series without the "fwspec
polishing":

Does a few things to prepare for the next:
- Clean up the call chains around dma_configure so the iommu_ops isn't being
exposed.
-
This is not being used to pass ops, it is just a way to tell if an
iommu driver was probed. These days this can be detected directly via
device_iommu_mapped(). Call device_iommu_mapped() in the two places that
need to check it and remove the iommu parameter everywhere.

A perfect driver would only call dev_iommu_priv_set() from its probe
callback. We've made it functionally correct to call it from the of_xlate
by adding a lock around that call.
lockdep assert that iommu_probe_device_lock is held to discourage misuse.
Exclude PPC kernels with CONFIG_FSL_PAMU turn
Nothing needs this pointer. Return a normal error code with the usual
IOMMU semantic that ENODEV means 'there is no IOMMU driver'.

Allocation of dev->iommu must be done under the
iommu_probe_device_lock. Mark this with lockdep to discourage future
mistakes.

Instead of returning 1 and trying to handle positive error codes just
stick to the convention of returning -ENODEV. Remove references to ops
from of_iommu_configure(), a NULL ops will already generate an error code.
There is no reason to check dev->bus, if err=0 at this point then the

This API was defined to formalize the access to internal iommu details on
some Tegra SOCs, but a few callers got missed. Add them.
The helper already masks by 0x so remove this code from the callers.

This also affects i.MX8MM, so better just mention i.MX in general in the
