Split Samsung Exynos SoC SYSREG bindings to own file to narrow the
bindings and do not allow other parts of syscon.yaml. This allows
further customization of Samsung SoC bindings.

We agree for add separate YAML for Samsung Exynos and hence I think we can
go ahead and add separate yaml for Tesla FSD.

Tesla FSD should go to the same file. No need for another binding for
same design...

Exynos5433 has several different SYSREGs, so use dedicated compatibles
for them.

Hi Krzysztof,
Just curious: what is the rationale for adding those more specific
sysregs? AFAIR, e.g. in Exynos850, different SysReg instances have
pretty much the same register layout.
Other than that:

On Exynos5433 all these blocks have different registers. Are you saying
that Exynos850 has four (or more) sysregs which are exactly the same?
Same registers? Why would they duplicate it?
Best regards,
Krzysztof

Ah, no, you are right. Just checked it, they are different. Just first
couple of registers are similar between blocks, that's why I memorized
it wrong.
So as I understand, adding those new compatibles follows "describe HW,
not a driver" rule? Because AFAIU, right now it'll fallback to
"syscon" compatible anyway.

Yes, they describe hardware. Of course all of these sysregs are similar
as they are just bunch of SFR/MMIO-region, but they have different
roles/features. For example some other devices (users) of syscon/sysreg
should reference specific device, not any sysreg.
On several other architectures we use specific compatibles, so I think
for Samsung we should do the same.
Different case was for Exynos 3/4/5 where there was only one SYSREG.
Best regards,
Krzysztof

Yes, these are dedicated / extended SFR region to provide IP/Block specific side-band signals / configurations.

Yes, most of the SoC's sysreg are dedicated/included in the IP block itself now a day, so make sense to have a dedicated compatible.

AFAIR, this is correct.

Because it should be used alone as unspecific.

Exynos850 has dedicated clock for accessing SYSREGs. Allow it, even
though Linux currently does not enable them and relies on bootloader.

Not sure if this description is correct. Of course, there is no driver
for "samsung,exynos850-sysreg" compatible at the moment, so the next
compatible from the list ("syscon") is used for Exynos850. And
"syscon" driver (drivers/mfd/syscon.c) actually does control the
clocks. I remember adding "clocks" property to Exynos850 dts to fix
actual problem. Also, the "clocks" property is not described in
Documentation/devicetree/bindings/mfd/syscon.yaml, didn't really check
if it's ok or it's just missing.
Other than that comment:

Ah, then commit msg is not good. I'll update it and maybe the clocks
should be required for Exynos850?

Yeah, looks like all Exynos850 sysreg blocks have dedicated clock.
Please make it required. And thanks for working on that! :)
