[PATCH net-next 0/2] dt-bindings: net: dsa: b53: Add YAML bindings

[PATCH net-next 0/2] dt-bindings: net: dsa: b53: Add YAML bindings

[Kurt Kanzenbach]

Hi,

the DSA device tree bindings have been converted to YAML. Let's start
using them. Convert the b53 bindings as suggested by Florian Fainelli.

[PATCH net-next 1/2] dt-bindings: net: dsa: b53: Add YAML bindings

[Kurt Kanzenbach]

Convert the b53 DSA device tree bindings to YAML in order to allow
for automatic checking and such.

Thanks for making this change, there are quite a few warnings that are 
going to show up because the binding was defined in a way that it would 
define chip compatible strings, which not all DTS files are using. I 
don't know if Rob would be comfortable with taking this until we resolve 
all warnings first.

Oh, I didn't know there is a second make command for doing the actual
check against the dtbs. I've just used `make dt_binding_check'.

So, it seems like a lot of the errors are caused by the include files
such as

[linux]/arch/arm/boot/dts/bcm5301x.dtsi

	srab: srab@18007000 {
		compatible = "brcm,bcm5301x-srab";
		reg = <0x18007000 0x1000>;

		status = "disabled";

		/* ports are defined in board DTS */
	};

The nodename should be "switch" not "srab" as enforced by
dsa.yaml. Furthermore, some DTS files are not adding the chip specific
compatible strings and the ports leading to more errors.

There are also some minor errors regarding the reg-names and such for
specific instances.

How should we proceed? Adding the missing compatible strings and ports
to the DTS files? Or adjusting the include files?

> I don't know if Rob would be comfortable with taking this until we

Probably not. We should fix the existing device trees first.

Thanks,
Kurt

The include is correct as it provides the fallback family string which 
is what the driver will be looking for unless we do not provide a chip 
compatible. The various DTS should be updated to contain both the chip 
compatible and the fallback family (brcm,bcm5301x-srab) string, I will 
update the various DTS and submit these for review later next week.

Then we could imagine me taking this YAML change through the Broadcom 
ARM SoC pull requests that way no new regressions are introduced.

Sounds good?

OK. It's not just the compatible strings, there are other issues as
well. You can check with `make dtbs_check DT_SCHEMA_FILES=path/to/b53.yaml'.

Sounds like a plan. But, Rob or other device tree maintainers should
have a look at the YAML file to spot issues in there first.

Thanks,
Kurt

I don't think that is necessary, I will do the clean-up of arch/arm/ and 
arch/arm64 and merge your two patches and submit everything as a series 
once completed. There is no rush here AFAICT.
