[PATCH 0/4] arm64: Initial support for Texas Instrument's J7200 Platform

[Lokesh Vutla]

This series adds initial support for latest new SoC, J7200, from Texas Instruments.

The J7200 SoC is a part of the K3 Multicore SoC architecture platform.
It is targeted for 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.

See J7200 Technical Reference Manual (SPRUIU1, June 2020)
for further details: https://www.ti.com/lit/pdf/spruiu1

Testing:
- Boot log: https://pastebin.ubuntu.com/p/FvpzWjf7tw/
- ./scripts/checkpatch --strict
	- Few warningns about Line length exceeding 100 columns.
	  But these are corresponding to comments

[PATCH 1/4] dt-bindings: arm: ti: Add bindings for J7200 SoC

[Lokesh Vutla]

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.

Lets convert the k3.txt to k3.yaml before we do anything more here.
Looking at the full series, I see that there are pending comments from
Grygorii as well which needs to be looked at. I have'nt seen a follow up
version since this version.

okay, I can switch Patch 1 and 2.

Can we return back
ti,sci-dev-id = <199>;

here? it's needed for DMA PSI-L pairing.

Option: add it as part of dma/net submission.

Oh, I wasn't aware of this. Lokesh removed it based on my earlier 
comments. Is this used by more than one driver? Anytime you see a 
ti,sci-dev-id, you would also expect to see the ti,sci reference in 
general for that driver to really leverage it.

The lack of a specific binding for this node also makes one think it is 
not needed.

Yeah, I think we should go with this approach on upstream if we aren't 
respinning the series. Any reason, this couldn't be added to the udma 
node itself?

Suman

[PATCH 4/4] arm64: dts: ti: Add support for J7200 Common Processor Board

[Lokesh Vutla]

Add support for J7200 Common Processor Board.
The EVM architecture is very similar to J721E as follows:

+------------------------------------------------------+
|   +-------------------------------------------+      |
|   |                                           |      |

|   |                                           |      |
|   +-------------------------------------------+      |
|                                                      |
|                                                      |
|                     +-------------------+            |
|                     |                   |            |
|                     |   SOM             |            |
|  +--------------+   |                   |            |
|  |              |   |                   |            |
|  |  Add-on      |   +-------------------+            |
|  |  Card 2      |                                    |    Power Supply
|  |  Options     |                                    |    |
|  |              |                                    |    |
|  +--------------+                                    | <---
+------------------------------------------------------+
                                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.
* Since J7200 is derivative of J721E re-using the CONFIG_ARCH_K3_J721E_SOC
  config for building J7200 dts files.

I have networking enabled on top of this series here.

ssh://git@bitbucket.itg.ti.com/~x1045550/ti-priv-linux-kernel.git ti-linux-5.4.y-for-next-pull

But DMA failed for Main domain.
     0.781005] ti-udma 31150000.dma-controller: NAVSS ti,sci-dev-id read failure -22
[    0.788684] ti-udma: probe of 31150000.dma-controller failed with error -22

http://lcpdresults.itg.ti.com/launcher/results/8013

Is there anything (except my comment for patch 3) which prevents this from been merged?
