[PATCH v1 0/4] Add support for TI AM6254atl SiP

[PATCH v1 0/4] Add support for TI AM6254atl SiP

[Anshul Dalal]

Hi all,

This patch series adds support for AM6254atl SiP (or AM62x SiP for short)
to the linux device-tree.

The OPN (Orderable Part Number) 'AM6254atl' expands as follows[1]:

AM6254atl
     ||||
     |||+-- Feature Lookup (L indicates 512MiB of integrated LPDDR4)
     ||+--- Device Speed Grade (T indicates 1.25GHz/1.4GHz on the A53 cores)
     |+---- Silicon PG Revision (A indicates SR 1.0)
     +----- Core configuration (4 indicates A53's in Quad core config)

AM62x SiP provides the existing AM62x SoC with 512MiB of DDR integrated in a
single packages.

This patch set adds the new 'k3-am6254atl' SoC level dtsi alongside the
'k3-am6254atl-sk' dts for the EVM (Evaluation Module board). The newly added
'k3-am625-sk-common' dtsi includes the common hardware between the existing
AM62x EVM and the new EVM for AM62x SiP.

Regards,
Anshul

[PATCH v1 1/4] arm64: dts: ti: k3-am62*: remove SoC dtsi from common dtsi

[Anshul Dalal]

The k3-am62x-sk-common dtsi represents the common hardware used across
am62x EVMs which can be configured with various DDR sizes or none (with
DDR integrated in the package) based on the specific am62x SoC used.

Therefore this patch moves the memory node and the SoC specific k3-am625
dtsi out of sk-common and into the board dts files. No functional change
is intended from this patch. The device-tree inheritance is changed as
follows:

Before:

               k3-am62
                 ^
               k3-am625
                 ^
         k3-am62x-sk-common
                 ^
  am62x EVMs (k3-am625-sk, k3-am62-lp-sk)

After:

        k3-am62
          ^
        k3-am625    k3-am62x-sk-common
          ^              ^
  am62x EVMs (k3-am625-sk, k3-am62-lp-sk)

[PATCH v1 4/4] arm64: dts: ti: Add support for AM6254atl SiP SK

[Anshul Dalal]

This patch adds the dt for SK-AM62-SIP, which uses the existing
SK-AM62 board design with the new AM6254atl SiP. This changes the
location of memory node from the board dts to SoC level dtsi
(k3-am6254atl in our case).

Therefore this patch introduces the new 'k3-am625-sk-common.dtsi'
which represents the common hardware used for both 'am625-sk' and
'am6254atl-sk' boards with the inheritance hierarchy modified to:

k3-am625-sk.dts:

     k3-am62    k3-am62x-sk-common
        |            |
    k3-am625    k3-am625-sk-common
        |            |
        +-----+------+
              |
         k3-am625-sk

k3-am6254atl-sk.dts:

     k3-am62
        |
     k3-am625       k3-am62x-sk-common
        |                |
