Commit Message

Add initial device tree support for "Full Self-Driving" (FSD) SoC
This SoC contain three clusters of four cortex-a72 CPUs and various
peripheral IPs.

+Cc Arnd,

Please Cc all SoC maintainers in new sub-architecture submissions, so
Olof and Arnd.

How similar it is? I think it is better to duplicate Exynos
selections/options here, instead of selecting entire ARCH. If this would
require "depends on ARCH_EXYNOS || ARCH_TESLA_FSD" everywhere in the
drivers, it's a hint that it is not a separate SoC but it is an Exynos,
so it might not need a new sub-architecture.

No, this is not a fsd.dts, but some board. You call FSD a SoC, so this
should have different name.

Wrong model, this is DTS, not DTSI.

Missing compatible for board.

These are not bootargs matching SoC. earlycon is purely a debug option.
console is duplicating stdout-path. root and init are also not a part of
DTSI or DTS.

The labels/overrides are with weird order... looks like a mess. Anyway,
clocks should be always enabled, why board has to enable them?

The same as clocks.

This looks wrong. There is nothing attached.

Same here and other I2C.

Nope, nope.

Can you imagine SoC with disabled DMA?

Same compatible as board - nope.

I think watchdogs do not need/use aliases.

You miss here some properties. Does your DTSI/DTS pass dtschema validation?

This explains why DTS has to enable basic SoC features... why do you
disable your clock controllers?

This property looks unsupported. Did you run dtschema checks?

Agreed, the SoC family options mainly exist so we can quickly enable or
disable drivers based on what a kernel is built for. If most of the drivers
for this SoC are shared with Exynos, I think having a single option is
sufficient, but it may be worth pointing out both in the help text.

If we want to have a separate option (mainly to help users find it), maybe
a 'depends on ARCH_EXYNOS' would be better. How many uses of
ARCH_TESLA_FSD are there?

Please make sure you run this thru 'make dtbs_check'. Fix schema
warnings as much as possible and all dtc warnings. If shared with
Samsung, there's probably a bit still missing. I see several warnings
so I won't bother manually reporting them here.

It is true that FSD shares few IPs with Exynos and it dose contains Telsa specific IPs/ PCIe/some of the PHYs/ GPUs (different then Exynos) etc. to name a few.
And drivers for those will be posted in upcoming phases by Samsung, Telsa etc.
AFA architecture is concerns both Exynos and FSD has completely different architecture (at least at HW level).
In my opinion, it is make sense to have a separate option for FSD.
And as Arnd suggested "'depends on ARCH_EXYNOS" may be the way forward.

Thanks Rob for review, let me fix them in patch set v2.
