As of commit c7289b1c8a ("arm64: tegra: Enable SMMU support on
Tegra194"), SMMU support is enabled system-wide on Tegra194. However,
there was a bit of overlap between the SMMU enablement and the USB
support addition, so the USB device tree nodes are missing the iommus
and interconnects properties. This in turn leads to SMMU faults for
these devices, since by default the ARM SMMU will fault.
Add the iommus and interconnects properties to the XUSB and XUDC device
tree nodes to restore their functionality.

Add iommus and interconnects properties to the sound device tree node on

physical to I/O virtual addresses and that the path to system memory is
properly described, which in turn can impact the range of memory that
the device can address.

Two carveout reserved memory nodes each have been added for each of the
R5F remote processor devices within the MAIN domain on the TI AM642 EVM
and SK boards. These nodes are assigned to the respective rproc device
nodes as well. The first region will be used as the DMA pool for the rproc
devices, and the second region will furnish the static carveout regions
for the firmware memory.
An additional reserved memory node is also added to reserve a portion of
the DDR memory to be used for performing inter-processor communication
between all the remote processors running RTOS or baremetal firmwares.
8 MB of memory is reserved for this purpose, and this accounts for all
the vrings and vring buffers between all the possible pairs of remote
processors.
The current carveout addresses and sizes are defined statically for each
rproc device. The R5F processors do not have an MMU, and as such require
the exact memory used by the firmwares to be set-aside. The firmware
images do not require any RSC_CARVEOUT entries in their resource tables
to allocate the memory for firmware memory segments.
NOTE:
1. The R5F1 carveouts are needed only if the R5F cluster is running in
Split (non Single-CPU) mode. The reserved memory nodes can be disabled
later on if there is no use-case defined to use the corresponding
remote processor.
2. The AM64x SoCs do not have any DSPs and one less R5F cluster compared
to J721E SoCs. So, while the carveout memories reserved for the R5F
clusters present on the SoC match to those on J721E, the overall
memory map reserved for firmwares is quite different. The number of
R5F clusters on AM64x SoCs are same as on J7200 SoCs, but the AM64x
SoCs also have an additional M4F core, so the RTOS IPC memory region
is 1 MB higher than on J7200 SoCs.

Add the required 'mboxes' property to all the R5F processors for the
TI AM642 EVM and SK boards. The mailboxes and some shared memory are
required for running the Remote Processor Messaging (RPMsg) stack
between the host processor and each of the R5Fs.
The chosen sub-mailboxes match the values used in the current firmware
images. This can be changed, if needed, as per the system integration
needs after making appropriate changes on the firmware side as well.
Note that any R5F Core1 resources are needed and used only when that
R5F cluster is configured for Split-mode.

The AM64x SoCs have 2 dual-core Arm Cortex-R5F processor (R5FSS)
subsystems/clusters. Both the R5F clusters are present within the
MAIN domain (MAIN_R5FSS0 & MAIN_R5FSS1). Each of these can be
configured at boot time to be either run in a new "Single-CPU" mode
or in an Asymmetric Multi Processing (AMP) fashion in Split-mode.
The mode is restricted to "Single-CPU" on some devices with the
appropriate eFuse bit set, but the most common devices support both
modes. These subsystems have 64 KB each Tightly-Coupled Memory (TCM)
internal memories for each core split between two banks - ATCM and
BTCM (further interleaved into two banks). The TCMs of both Cores
are combined in Single-CPU mode to provide a larger 128 KB of memory.
The other notable difference is that the TCMs are spaced 1 MB apart
on these SoCs unlike the existing SoCs.
Add the DT nodes for both these MAIN domain R5F cluster/subsystems,
the two R5F cores are added as child nodes to each of the corresponding
R5F cluster node. Both the clusters are configured to run in Split mode
by default, with the ATCMs enabled to allow the R5 cores to execute
code from DDR with boot-strapping code from ATCM. The inter-processor
communication between the main A72 cores and these processors is
achieved through shared memory and Mailboxes.
The following firmware names are used by default for these cores, and
can be overridden in a board dts file if desired:
MAIN R5FSS0 Core0: am64-main-r5f0_0-fw (both in Single-CPU & Split modes)
MAIN R5FSS0 Core1: am64-main-r5f0_1-fw (needed only in Split mode)
MAIN R5FSS1 Core0: am64-main-r5f1_0-fw (both in Single-CPU & Split modes)
MAIN R5FSS1 Core1: am64-main-r5f1_1-fw (needed only in Split mode)
NOTE:
A R5FSS cluster can be configured in "Single-CPU" mode by using a
value of 2 for the "ti,cluster-mode" property. Value of 1 is not
permitted (fails the dtbs_check).

A recent switch to a dedicated AP807 compatible string for the Xenon
SD/MMC controller result in the driver not being probed when
using updated device tree with the older kernel revisions.
It may also be problematic for other OSs/firmware that use
Linux device tree sources as a reference. Resolve the problem
with backward compatibility by restoring a previous compatible
string as secondary one.
