[PATCH 00/10] Broadcom b53 YAML bindings

[PATCH 00/10] Broadcom b53 YAML bindings

[Florian Fainelli]

Hi,

This patch series fixes the various Broadcom SoCs DTS files and the
existing YAML binding for missing properties before adding a proper b53
switch YAML binding from Kurt.

If this all looks good, given that there are quite a few changes to the
DTS files, it might be best if I take them through the upcoming Broadcom
ARM SoC pull requests. Let me know if you would like those patches to be
applied differently.

Thanks!

[PATCH 01/10] dt-bindings: net: dsa: Extend switch nodes pattern

[Florian Fainelli]

Upon discussion with Kurt, Rob and Vladimir it appears that we should be
allowing ethernet-switch as a node name, update dsa.yaml accordingly.

[PATCH 02/10] dt-bindings: net: dsa: Document sfp and managed properties

[Florian Fainelli]

The 'sfp' and 'managed' properties are commonly used to describe
Ethernet switch ports connecting to SFP/SFF cages, describe these two
properties as valid that we inherit from ethernet-controller.yaml.

You're lucky that you don't have any firmware that fixes up DT
properties by path.

Nice, I didn't know DSA supported the switch inside this device. In the
default AsusWRT, the switch is well hidden from the kernel :)

Not that it makes any difference as far as I can see, but how do you
know this a BCM53010 SRAB specifically?

Yeah right :) The YAML validation works even when the nodes are
disabled, so we somehow need to account for all of these devices' DTS.

The 4708 is effectively a 53010 which is why this is valid as a
fallback. Any node that defines switch ports and uses a SoC different
than the 53010 should use an appropriate "compatible" string though.
That's what is done for NSP.

This look a bit 'lone wolf' here. Not sure how much time you intend to
spend on this, but FWIW, others prefer to declare all ports in the SoC
DTSI with status = "disabled", and just enable the ones used per-board,
and add labels and PHY handles also per-board. Example: fsl-ls1028a.dtsi
and fsl-ls1028a-rdb.dts.

I.e. no one calls devm_platform_ioremap_resource(pdev, 2), and even if
it did, the register name wouldn't matter.
...but at least it's documented that it should be called "sgmii_config".
And the address is the same as the one that's documented for the SGMII
register base in SoCs with "brcm,nsp-srab", so even without
documentation, it is pretty clear to me that it was a mistake calling it
simply "sgmii". And if that address is incorrect anyways, at least that
would be a separate issue.

I am not getting this.
The line:
#include "bcm-nsp.dtsi"

can be found in:

arch/arm/boot/dts/bcm988312hr.dts
arch/arm/boot/dts/bcm958625hr.dts
arch/arm/boot/dts/bcm958622hr.dts
arch/arm/boot/dts/bcm958625k.dts
arch/arm/boot/dts/bcm958522er.dts
arch/arm/boot/dts/bcm958525er.dts
arch/arm/boot/dts/bcm958623hr.dts
arch/arm/boot/dts/bcm958525xmc.dts


The pattern for the other DTS files that include this seems to be to
overwrite the compatible locally in bcm958522er.dts, like this:

&srab {
	compatible = "brcm,bcm58522-srab", "brcm,nsp-srab";
};

Is there a reason why you are choosing to put an SoC specific compatible
in the common bcm-nsp.dtsi?

It is necessary to silence the warnings provided in the commit message
even when the srab node is disabled, since the dt_binding_check rule
will check all of the nodes matching the pattern. If there is a better
way to do this, I would gladly do it differently.

I am only reading these with a human eye, I don't parse YAML syntax.
Does the syntax enforce that these reg-names are declared in this
precise order, which is necessary for the proper operation of the
driver?

You have renamed a node called 'ethernet-switch' into one called
'switch'. Was it deliberate?

I am still not getting it. The exact 3 lines from above will not change
the "status" property from "disabled" to "okay", so I don't understand
why it matters whether it's enabled or not. The dt_binding_check error
isn't in the DTSI, it's in bcm958522er.dts. All that needs to be done is
that the bcm958522er.dts needs to override the compatible from the DTSI
and only the compatible, I believe. With no occurrence of an incomplete
list of compatibles in any final DTS, the dt_binding_check should not
complain about that single occurrence in the DTSI as far as I know (and
I did not test this).

There is not a switch being enabled in
arch/arm/boot/dts/bcm958522er.dts, so sure, I could add the 3 lines you
quote above and that would silence the warning, but that does not scale
at all across DTS files including bcm5301x.dtsi for instance, it sort of
does for those including bcm-nsp.dtsi.

I see only bcm47081.dtsi and bcm4708.dtsi to include bcm5301x.dtsi, and
you did point out in the other email that the BCM4708* SoCs always
contain a BCM53010 switch, so that would make the other patch not wrong.

Either way, it's up to you and Rafal.

There is quite a bit of variation between designs and how the ports are
assigned and it would end up being quite verbose, so I will punt that
for now.

I agree with Florian, boards (vendors) use ports really randomly so pretty
much every device needs that defined from the scratch.
