Hi,

This series adds support for the latest new SoC, J721E, from Texas Instruments.

The series is an based off v5.2-rc1 and has the following driver
dependencies for a successful boot:
1.  https://lore.kernel.org/lkml/20190429131533.25122-1-afd@ti.com (for newer firmware)
2.  https://lore.kernel.org/linux-arm-kernel/1555093342-428-1-git-send-email-t-kristo@ti.com/
    - Clock IDs cannot be guarenteed to be sequential, has to be
      discovered from hardware description in dts
    - Clock IDs on this massive chip also exceeds 255, so, the support
      for the same is expected in follow on patches.

The full series is available here (including dependencies):
https://github.com/nmenon/linux-2.6-playground/commits/upstream/v5.2-rc1/j7es-base-v1

Boot Log: https://pastebin.ubuntu.com/p/j3NtfF8FQr/

NOTE:
 - If Greg is ok, we can pick up the uart compatibility via the k3 tree,
   else, I can spawn it off the series.
 - I will resubmit patch 6 (defconfig update) separately once again once
   patches 1-5 hit the next tree or for 5.3-rc2 which ever is convenient.

The J721E SoC belongs to the K3 Multicore SoC architecture platform
for automotive applications such as infotainment, cluster, premium
Audio, Gateway, industrial and a range of broad market applications.
This SoC is designed around reducing the system cost by eliminating
the need of an external system MCU and is targeted towards ASIL-B/C
certification/requirements in addition to allowing complex software
and system use-cases.

The Linux development follows AM654 in most of the configurations, but
adds new capabilities (details in follow on patches).

See J721E Technical Reference Manual (SPRUIL1, May 2019)

The J721E SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable lower system costs
of automotive applications such as infotainment, cluster, premium
Audio, Gateway, industrial and a range of broad market applications.
This SoC is designed around reducing the system cost by eliminating
the need of an external system MCU and is targeted towards ASIL-B/C
certification/requirements in addition to allowing complex software
and system use-cases.

Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep
  capable dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA),
  C7x floating point Vector DSP, Two C66x floating point DSPs.
* 3D GPU PowerVR Rogue 8XE GE8430
* Vision Processing Accelerator (VPAC) with image signal processor and Depth
  and Motion Processing Accelerator (DMPAC)
* Two Gigabit Industrial Communication Subsystems (ICSSG), each with dual
  PRUs and dual RTUs
* Two CSI2.0 4L RX plus one CSI2.0 4L TX, one eDP/DP, One DSI Tx, and
  up to two DPI interfaces.
* Integrated Ethernet switch supporting up to a total of 8 external ports in
  addition to legacy Ethernet switch of up to 2 ports.
* System MMU (SMMU) Version 3.0 and advanced virtualisation
  capabilities.
* Upto 4 PCIe-GEN3 controllers, 2 USB3.0 Dual-role device subsystems,
  16 MCANs, 12 McASP, eMMC and SD, UFS, OSPI/HyperBus memory controller, QSPI,
  I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Two hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
  management.
* Configurable L3 Cache and IO-coherent architecture with high data throughput
  capable distributed DMA architecture under NAVSS
* Centralized System Controller for Security, Power, and Resource
  Management (DMSC)

J721e uses a UART controller that is compatible with AM654 UART.
Introduce a specific compatible to help handle the differences if
necessary.

   else, I can spawn it off the series into it's own patch, but it
   seemed better in a logical order.

                                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. Add-n card
options add further functionality (such as additional Audio, Display,
networking options).

Note:
A) The minimum configuration required to boot up the board is System On
   Module(SOM) + Common Processor Board.
B) 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.
C) All daughter cards beyond the basic boards shall be maintained as
   overlays.

NOTE:
 - I will resubmit this patch (defconfig update) separately once again once
   patches 1-7 hit the next tree or for 5.3-rc2 which ever is convenient.

Other than that, everything looks good.

ti,scan-clocks-from-dt is an invalid DT property, it was NAK:ed a while 
back. The same functionality is now going to be used by default, so the 
property is not needed anyway.

Fixed this locally by dropping the property.

Assuming here that Greg is ok with me picking up patch #2.

Seems it should be possible just to queue up everything, no need to 
repost stuff.

That said, queuing the whole series towards 5.3 with the mentioned fixes.
