[v2,3/4] 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.

These nodes are enabled by default right? Above is redundant.

Seems like historic left-overs here - fixed.

At least to my understanding, "rohm,dh2228fv" is commonly used for
declaring spidev, and this is what we need for userland here.

Jan,

Could you post the full series as V3 please? it works better
that way for b4 workflow for me.

Jan,

I am not sure if
https://lore.kernel.org/linux-arm-kernel/20210304160712.8452-2-s-anna@ti.com/
is going to impact your platform. I am planning on picking that series up today.
might be good to test against tomorrow's next - running through my basic
tests right now before committing to the ICSS-G nodes being picked up.

If you could repost after testing against tomorrow's next, it will
probably be better.

Thanks, I was already on CC. That series does not affect the board
features as configured in this patch. However, we are eagerly awaiting
ISCCG and then PRU Ethernet support in upstream as this is used on our
boards, with both SR1.0 and (upcoming) SR2.0.

However, I can update [1] with that series and retest our staging
integration. But as you can see from the topmost commit, it is
constantly shaking as upstreaming goes on.

Yep, hopefully things should settle down soon-ish, I hope. Thanks for
