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

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
