e0133f883c arm64: dts: ti: iot2050: Disable lock-step for all iot2050 boards
The PG1 A variant of the iot2050 series has been identified which
partially lacks support for lock-step mode. This implies that all
iot2050 boards can't support this mode. As a result, lock-step mode has
been disabled across all iot2050 boards for consistency and to avoid
potential issues.

93abe383bf arm64: dts: ti: iot2050: Disable R5 lockstep for all PG2 boards
The R5 lockstep disabling should be common for all PG2 boards, move it
from variants dts to common-pg2.dtsi.

As now the Basic PG2 consumes this twice, move Basic disabling to the
PG1 variant.

a9dbf044c6 arm64: dts: ti: iot2050: Prepare for adding 2nd-generation boards
The current IOT2050 devices are Product Generation 1 (PG1), using SR1.0
AM65x silicon. Upcoming PG2 devices will use SR2.x SoCs and will
therefore need separate device trees. Prepare for that by factoring out
common bits that will be shared across both generations.

At this chance, drop a link to the product homepage to in the top-level
dts files. Also fix a typo in my email address in some headers.

Lockstep mode is not supported here. So turn it off to avoid warnings
during startup.

e180f76d06 arm64: dts: ti: Add support for Siemens IOT2050 boards
Add support for two Siemens SIMATIC IOT2050 variants, Basic and
Advanced. They are based on the TI AM6528 GP and AM6548 SOCs HS, thus
differ in their number of cores and availability of security features.
Furthermore the Advanced version comes with more RAM, an eMMC and a few
internal differences.

Based on original version by Le Jin.
