Add the Blueridge and Fuji BMC systems. Document many missing FSI related
properties, and fix existing warnings. Make some minor fixes in OCC and
SCOM drivers for the updated bindings.

Changes since v2:
 - Split up the DTS patches
 - Add documentation patches

Changes since v3:
 - Remove references to fsi.txt
 - Change ibm,p10-spi to ibm,spi-fsi
 - Change ibm,fsi2pib to ibm,p9-scom
 - Change ibm,hub-fsi-controller to ibm,p9-fsi-controller
 - Fix warnings
 - Fix formatting
 - Add device driver fixes

IBM Power processors have a SPI controller that can be accessed
over FSI from a service processor. Document it.

Changes since v2: 
 - Change name from ibm,p10-spi to ibm,spi-fsi for two reasons. One, this
   matches the I2C controller binding (ibm,i2c-fsi), and two, this binding
   is specifically for the FSI-attached SPI controllers on the P10 but
   accessed from the service processor. P10 SPI controllers accessed from
   the P10 would have different bindings.
 - Fix warnings by using generic FSI parent node
 - Fix prefix

The FSI2SPI bridge has several SPI controllers behind it, which
should be documented. Also, therefore the node needs to specify
address and size cells.

Conver to json-schema for the OCC documentation. Also document the fact
that the OCC "bridge" device will often have the hwmon node as a
child.

 - Drop "occ-" in child node

Since there are multiple FSI controllers documented, the common
properties should be documented separately and then referenced
from the specific controller documentation.

Changes since v3:
 - Add chip-id description

+  This I2C controller is an FSI CFAM engine, providing access to a number of

Add the P11 FSI device tree for use in upcoming BMC systems.
Unlike P10, there is no system with only two processors, so
only the quad processor FSI layout is necessary.

Changes since v3:
 - Re-order everything

Remove the IDA indexing for OCC devices and instead use the FSI
minor number API. This will make the OCC numbering consistent
with other FSI engines and make the "reg" device tree property
unnecessary.

There's no reason to restrict the creation of the hwmon device to
a matching child node name. Just get the first available one. There
should only be one child node anyway.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

And now it raises questions:
1. Other devices on FSI bus have unit addresses, so why this does not?
2. This suggest only one hwmon, so ^hwmon$, which is then not a
patternProperty but property.
3. But the true problem why do you even need two empty nodes? These
should be combined into one node.

There was no such compatible before.

How does this even validate? Where is fsi-master? You dropped a
compatible without any explanation.

Please split independent patches to separate patchsets, so they can be
reviewed and picked up by respective maintainers.

I don't see any dependency here. Neither in 1st patch.

This does not look right. Why do you have multiple i2c-bus children? I
do not think i2c-controller.yaml schema allows this.

1. This is not truly on the FSI bus. It is on the SBEFIFO "bus"

2. True enough, I'll change it to property.

3. If this binding was being designed now, I'd agree with you, but the 
two nodes (occ and occ-hwmon) are already documented, I'm just changing 
to yaml here... Changing that would require a lot of changes and would 
break the two drivers.

The other two are already documented... The SBEFIFO should have 
documented a long time ago, and designed accordingly. However keep in 
mind, the OCC nodes are optional on SBEFIFOs, since the Odyssey chip 
SBEFIFOs are not connected to OCCs.


Thanks for your detailed review.

I can make it a separate change to add ast2700.


I suppose I don't understand having two compatibles... Aspeed master 
shouldn't use "fsi-master" as that is too generic, right? Why wouldn't 
it validate? Devicetrees using "fsi-master" also use 
"aspeed,ast2600-fsi-master" so they should be OK...

OK, I guess that makes it complicated for Andrew to pull together with 
the device tree changes in a way that avoids warnings, but I agree there 
is no direct dependency.

It does seem to allow it, as this validates here and in the device tree. 
It is this way because the I2C controller provides multiple busses. 
Should I change it so to add "bus" pattern properties that reference 
i2c-controller.yaml?


Thanks,

Eddie

SoC tree should not pull subsystem patches. Plus DTS must be separate
from drivers...

Only because children are treated as I2C devices.

> It is this way because the I2C controller provides multiple busses. 

It does not look like I2C controller anymore. I think I2C controller
sits on the bus, not on multiple busses. How are SDA/SCL lines connected?

This looks like you are describing something which is not I2C bus
controller as I2C bus controller...

I'll let I2C maintainer comment on that - is this real I2C bus which
consists of multiple buses.


> Should I change it so to add "bus" pattern properties that reference

Not sure if I get it right... whatever is the I2C bus controller, should
reference i2c-controller.yaml. Not some other entity.

Krzysztof

No child was documented before and documenting things post-factum does
not allow to bypass regular review rules.

Not necessarily, depends. Dropping it silently is confusing. What about
other users? firmware, bootloaders, out-of-tree, other OS? Did you
investigate all of them?

> it validate? Devicetrees using "fsi-master" also use

No, because the compatibles do not match. Run validation and you will
see the errors.

I am fine with dropping such compatible, which is not used by current
kernel ABI, but first DTS must be fixed and second some explanation and
justification is needed.

Best regards,
Krzysztof

The old format file actually only used fsi-master in the example, not in 
the actual properties description. So I didn't really drop a compatible. 
Device trees using "fsi-master" are just buggy and should be fixed 
eventually, but I don't think it needs to be part of this series.


Thanks,

Eddie
