commit 50301e8815c681bc5de8ca7050c4b426923d4e19 upstream.
DSS is IO coherent on AM65, so we should mark it as such with
'dma-coherent' property in the DT file.

The board uses lane 3 of SERDES for USB. Set the mux
accordingly.
The USB controller and EVM supports super-speed for USB0
on the Type-C port. However, the SERDES has a limitation
that upto 2 protocols can be used at a time. The SERDES is
wired for PCIe, QSGMII and USB super-speed. It has been
chosen to use PCI2 and QSGMII as default. So restrict
USB0 to high-speed mode.

Common Processor Board
Common Processor board is the baseboard that has most of the actual
connectors, power supply etc. A SOM (System on Module) is plugged on
to the common processor board and this contains the SoC, PMIC, DDR and
basic high speed components necessary for functionality.
Note:
* The minimum configuration required to boot up the board is System On
Module(SOM) + Common Processor Board.
* Since there is just a single SOM and Common Processor Board, we are
maintaining common processor board as the base dts and SOM as the dtsi
that we include. In the future as more SOM's appear, we should move
common processor board as a dtsi and include configurations as dts.
* All daughter cards beyond the basic boards shall be maintained as
overlays.

The J7200 SoC is a part of the K3 Multicore SoC architecture platform.
It is targeted for automotive gateway, vehicle compute systems,
Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications.
The SoC aims to meet the complex processing needs of modern embedded
products.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, two clusters of lockstep
capable dual Cortex-R5F MCUs and a Centralized Device Management and
Security Controller (DMSC).
* Configurable L3 Cache and IO-coherent architecture with high data
throughput capable distributed DMA architecture under NAVSS.
* Integrated Ethernet switch supporting up to a total of 4 external ports
in addition to legacy Ethernet switch of up to 2 ports.
* Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems,
20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C
and I2C, eCAP/eQEP, eHRPWM among other peripherals.
* One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
management.

J721E EVM boards. These nodes are assigned to the respective rproc device

The current carveout addresses and sizes are defined statically for each

currently supported and as such requires the exact memory used by the
firmware to be set-aside. The firmware images currently do not need any
RSC_CARVEOUT entries either in their resource tables to allocate the
memory for firmware memory segments.
The reserved memory nodes can be disabled later on if there is no use-case

Two carveout reserved memory nodes each have been added for each of the
C66x DSP remote processor devices present within the MAIN voltage domain
for the TI J721E EVM 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

The minimum granularity on the Cache settings on C66x DSP cores is 16 MB,
so the DMA memory regions are chosen such that they are in separate 16 MB
regions for each DSP, while reserving a total of 16 MB for each DSP and
not changing the overall DSP remoteproc carveouts.
The current carveout addresses and sizes are defined statically for each

Add the required 'mboxes' property to both the C66x DSP processors for the
TI J721E common processor board. The mailboxes and some shared memory are
required for running the Remote Processor Messaging (RPMsg) stack between
the host processor and each of the DSPs. The nodes are therefore added
in the common k3-j721e-som-p0.dtsi file so that all of these can be
co-located.
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.

The J721E SoCs have two TMS320C66x DSP Core Subsystems (C66x CorePacs)
in the MAIN voltage domain, each with a C66x Fixed/Floating-Point DSP
Core, and 32 KB of L1P & L1D configurable SRAMs/Cache and an additional
288 KB of L2 configurable SRAM/Cache. These subsystems do not have
an MMU but contain a Region Address Translator (RAT) sub-module for
translating 32-bit processor addresses into larger bus addresses.
The inter-processor communication between the main A72 cores and
these processors is achieved through shared memory and Mailboxes.
Add the DT nodes for these DSP processor sub-systems in the common
k3-j721e-main.dtsi file.
The following firmware names are used by default for these cores, and
can be overridden in a board dts file if desired:
C66x_0 DSP: j7-c66_0-fw
C66x_1 DSP: j7-c66_1-fw

The commit eb9f9173d01f ("arm64: dts: ti: k3-j721e-common-proc-board:
Add IPC sub-mailbox nodes") has added the sub-mailbox nodes used by
various remote processors and disabled the unused mailbox clusters
directly in the k3-j721e-common-proc-board dts file. Move all of these
nodes into the k3-j721e-som-p0.dtsi file instead to co-locate all the
mailboxes and the soon to be added DDR reserved-memory carveout nodes
used by remoteprocs within the same dtsi file.

The various CBASS interconnect nodes on K3 J721E SoCs are defined
using the node name "interconnect". This is not a valid node name
as per the dt-schema. Fix these node names to use the standard name
used for SoC interconnects, "bus".

The Type-C compainon chip on the board needs ~133ms (tCCB_DEFAULT)
to debounce the CC lines in order to detect attach and plug orientation
and reflect the correct DIR status. [1]
On the EVM however we need to wait upto 700ms before sampling the
Type-C DIR line else we can get incorrect direction state.
