6799e3f281 dt-bindings: net: renesas,etheravb: Fix optional second clock name
If the optional "clock-names" property is present, but the optional TXC
reference clock is not, "make dtbs_check" complains:

    ethernet@e6800000: clock-names: ['fck'] is too short

Fix this by declaring that a single clock name is valid.
While at it, drop the superfluous upper limit on the number of clocks,
as it is implied by the list of descriptions.

6f43735b6d dt-bindings: net: renesas,etheravb: Add additional clocks
The AVB driver assumes there is an external crystal, but it could
be clocked by other means.  In order to enable a programmable
clock, it needs to be added to the clocks list and enabled in the
driver.  Since there currently only one clock, there is no
clock-names list either.

Update bindings to add the additional optional clock, and explicitly
name both of them.

ca649ccae4 dt-bindings: net: renesas,etheravb: Add r8a779a0 support
Document the compatible value for the RAVB block in the Renesas R-Car
V3U (R8A779A0) SoC. This variant has no stream buffer, so we only need
to add the new compatible and add it to the TX delay block.

f97844f9c5 dt-bindings: net: renesas,etheravb: RZ/G2H needs tx-internal-delay-ps
The merge resolution of the interaction of commits 307eea32b2
("dt-bindings: net: renesas,ravb: Add support for r8a774e1 SoC") and
d7adf63311 ("dt-bindings: net: renesas,etheravb: Convert to
json-schema") missed that "tx-internal-delay-ps" should be a required
property on RZ/G2H.

8b0308fe31 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Rejecting non-native endian BTF overlapped with the addition
of support for it.

The rest were more simple overlapping changes, except the
renesas ravb binding update, which had to follow a file
move as well as a YAML conversion.

d7adf63311 dt-bindings: net: renesas,etheravb: Convert to json-schema
Convert the Renesas Ethernet AVB (EthernetAVB-IF) Device Tree binding
documentation to json-schema.

Add missing properties.
Update the example to match reality.
