[PATCH 0/6] arm64: Initial support Texas Instrument's J721E Platform

[Nishanth Menon]

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@xxxxxx (for newer firmware)
2.  https://lore.kernel.org/linux-arm-kernel/1555093342-428-1-git-send-email-t-kristo@xxxxxx/
    - 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)
