[PATCH v2 0/4] arm64: Add TI AM65x-based IOT2050 boards

[Jan Kiszka]

Changes in v2:
 - address board-specific issues found by kernel_verify_patch
 - remove dead l2-cache node from iot2050-basic DT
 - add binding for Siemens vendor prefix
 - factor out board bindings into separate patch
 - add missing device_type to common ti,am654-pcie-rc nodes

[PATCH v2 3/4] arm64: dts: ti: Add support for Siemens IOT2050 boards

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

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.

[PATCH v2 3/4] arm64: dts: ti: Add support for Siemens IOT2050 boards

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

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.

At this chance the note that booting mainline requires WiP mainline 
firmware which can be built from [1] already. But installing it is at 
own risk until we released it officially.

Hi Jan Kiszka,

I have picked patch #4 in your series to the following to branch
ti-k3-dts-next on [1]. Thank you! Rest of the series will have to be
reposted *after* Rob Herring Acks the bindings (monitor status in
queue [2]).

[4/4] arm64: dts: ti: k3-am65-main: Add device_type to pcie*_rc nodes
      commit: 0d7571c36331aafce485fa105959b498c86615d7

I have picked patch #4 for the next kernel window for now, given it is
a trivial fix.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

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

[PATCH v3 3/4] arm64: dts: ti: Add support for Siemens IOT2050 boards

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

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.

[PATCH v3 3/4] arm64: dts: ti: Add support for Siemens IOT2050 boards

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

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.

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.
