Make trivial changes on the binding.
- Update title to include MT7531 switch.
- Add me as a maintainer. List maintainers in alphabetical order by first
name.
- Add description to compatible strings.
- Stretch descriptions up to the 80 character limit.
- Remove quotes from $ref: "dsa.yaml#".

- Fix description of mediatek,mcm. mediatek,mcm is not used on MT7623NI.
- Add description for reset-gpios.
- Invalidate reset-gpios if mediatek,mcm is used.
- Invalidate mediatek,mcm if the compatible device is mediatek,mt7531.
- Require mediatek,mcm for the described MT7621 SoCs as the compatible
string is only used for MT7530 which is a part of the multi-chip module.

The commit message should answer 'why is this change needed/wanted?' not
'what changed'. I can read the diff to see what changed.

Update the examples on the binding.
- Add examples which include a wide variation of configurations.
- Make example comments YAML comment instead of DT binding comment.
- Define examples from platform to make the bindings clearer.
- Add interrupt controller to the examples. Include header file for
interrupt.
- Change reset line for MT7621 examples.
- Pretty formatting for the examples.
- Change switch reg to 0.
- Change port labels to fit the example, change port 4 label to wan.
- Change ethernet-ports to ports.

'ports' is for the DT graph binding. 'ethernet-ports' is for DSA
binding. The former is allowed due to existing users. Don't add more.

Looks almost the same as example 1. Examples are not an enumeration of
every possible DT. Limit them to cases which are significantly
different.

No need to put this in the example. We don't put provide nodes in
the examples of the consumers. It's also incomplete and can't be
validated.

It seemed to me it would be useful to reference the reset line for the
MT7623AI SoC. Using mediatek,mcm and especially MT2701_ETHSYS_MCM_RST in
dt-bindings/reset/mt2701-resets.h.
Should I remove anyway?

my comments from v1 apply here
None of the reasons you said force you to define properties in some
allOf:if:then subblock. These force you to constrain the properties in
allOf:if:then, but not define.
> I can split patternProperties to two sections, but I can't directly
> define the reg property like you put above.
Of course you can and original bindings were doing it.
Let me ask specific questions (yes, no):
1. Are ethernet-ports and ethernet-port present in each variant?
2. Is dsa-port.yaml applicable to each variant? (looks like that - three
compatibles, three all:if:then)
3. If reg appearing in each variant?
4. If above is true, if reg is maximum one item in each variant?
Looking at your patch, I think answer is 4x yes, which means you can
define them in one place and constrain in allOf:if:then, just like all
other schemas, because this one is not different.
Best regards,
Krzysztof

All yes.

If I understand correctly, I do this already with v3. Properties are
defined under the constructed node. Accepted values for properties are
constrained under if:then.

I can describe it on the binding description but it won't be checked on
DT bindings. phy-mode values are significantly different between mt7530
and mt7531 so I think it's useful to have it.

Update the description of the binding.
- Describe the switches, which SoCs they are in, or if they are standalone.
- Explain the various ways of configuring MT7530's port 5.
- Remove phy-mode = "rgmii-txid" from description. Same code path is
followed for delayed rgmii and rgmii phy-mode on mtk_eth_soc.c.

+ There are two versions of MT7530, standalone and in a multi-chip module.
+
+ MT7530 is a part of the multi-chip module in MT7620AN, MT7620DA, MT7620DAN,
+ MT7620NN, MT7621AT, MT7621DAT, MT7621ST and MT7623AI SoCs.
+
+ MT7530 in MT7620AN, MT7620DA, MT7620DAN and MT7620NN SoCs has got 10/100 PHYs
+ and the switch registers are directly mapped into SoC's memory map rather than
+ using MDIO. There is currently no support for this.
+
+ There is only the standalone version of MT7531.
+
+ Port 5 on MT7530 has got various ways of configuration.
+
+ For standalone MT7530:
+
+ - Port 5 can be used as a CPU port.
+
+ - PHY 0 or 4 of the switch can be muxed to connect to the gmac of the SoC
+ which port 5 is wired to. Usually used for connecting the wan port
+ directly to the CPU to achieve 2 Gbps routing in total.
+
+ The driver looks up the reg on the ethernet-phy node which the phy-handle
+ property refers to on the gmac node to mux the specified phy.
+
+ The driver requires the gmac of the SoC to have "mediatek,eth-mac" as the
+ compatible string and the reg must be 1. So, for now, only gmac1 of an
+ MediaTek SoC can benefit this. Banana Pi BPI-R2 suits this.
+ Check out example 5 for a similar configuration.
+
+ - Port 5 can be wired to an external phy. Port 5 becomes a DSA slave.
+ Check out example 7 for a similar configuration.
+
+ For multi-chip module MT7530:
+
+ - Port 5 can be used as a CPU port.
+
+ - PHY 0 or 4 of the switch can be muxed to connect to gmac1 of the SoC.
+ Usually used for connecting the wan port directly to the CPU to achieve 2
+ Gbps routing in total.
+
+ The driver looks up the reg on the ethernet-phy node which the phy-handle
+ property refers to on the gmac node to mux the specified phy.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+ Check out example 5.
+
+ - In case of an external phy wired to gmac1 of the SoC, port 5 must not be
+ enabled.
+
+ In case of muxing PHY 0 or 4, the external phy must not be enabled.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with rgmii2 function.
+ Check out example 6.
+
+ - Port 5 can be muxed to an external phy. Port 5 becomes a DSA slave.
+ The external phy must be wired TX to TX to gmac1 of the SoC for this to
+ work. Ubiquiti EdgeRouter X SFP is wired this way.
+
+ Muxing PHY 0 or 4 won't work when the external phy is connected TX to TX.
+
+ For the MT7621 SoCs, rgmii2 group must be claimed with gpio function.

In the driver. Also, did you mean irrelevant? Should I remove this part
from the binding?
