[PATCH 0/4] arm64: dts: renesas: Fix PHY C22 compatible strings

[Marek Vasut]

Realtek RTL8211E/RTL8211F and Microchip KSZ9131 PHY schemas
indicate that compatible string "ethernet-phy-id001c.c91[56]"
and "ethernet-phy-id0022.1640" must not be followed by any
other compatible string. Drop "ethernet-phy-ieee802.3-c22"
to match the schemas.

The KSZ9131 schema does not document "txdv-skew-psec" property.
Fix what is likely a copy-paste error from the "rxdv-skew-psec"
property, use "txen-skew-psec" property instead.

This is compile-tested and schema validated only. I have discussed
this with Biju and they could perform tests on real hardware to
assure no breakage. Please wait for their TB before applying.

[PATCH 4/4] arm64: dts: renesas: Fix KSZ9131 PHY bogus txdv-skew-psec property

[Marek Vasut]

The KSZ9131 schema does not document "txdv-skew-psec" property, neither
does the kernel driver support this property. It does however document
and support "txen-skew-psec" property. Fix what is likely a copy-paste
error from the matching "rxdv-skew-psec" property, use "txen-skew-psec"
property instead of "txdv-skew-psec" property.

Looks like there is delay in delivering my patches. I already posted 3 patches. I will test 4/4.

I haven't seen these patches.

It does not cover all the SoCs/boards. If Marek want to take over, He can send next version
covering all Renesas boards + binding change.

I am happy with that.

Isn't this series effectively exactly that ?

You have covered only 9 SoCs [1] Whereas the patch series I posted covers
43 SoCs[2].

I also did not modify any of the YAML schemas, I only fixed the errors 
that were detected in next by the existing schemas. Maybe fixing of 
errors should happen first, and adjustment of schemas and further follow 
up clean ups can happen second ?

I believe we still have e.g. the KSZ8041 and KSZ9031 PHY nodes to fix,
for both RZ and R-Car boards? Some of them were covered by [1] and
[2] above.
Thanks!

I hope this is now all addressed by two board fixes [3] [4] and one 
larger fix [5]. But there are also other warnings on the arm32 side 
which are not related to ethernet schemas.
