dt-bindings: net: dsa: mediatek,mt7530: expand gpio-controller description

2022-09-23T09:24:58Z

Expand the description of the gpio-controller property to include the controllable pins of the MT7530 switch. The gpio-controller property is only used for the MT7530 switch. Therefore, invalidate it for the MT7531 switch. Signed-off-by: Arınç ÜNAL Acked-by: Rob Herring Signed-off-by: David S. Miller

dt-bindings: net: dsa: mediatek,mt7530: change mt7530 switch address

2022-09-23T09:24:58Z

In the case of muxing phy0 of the MT7530 switch, the switch and the phy will have the same address on the mdio bus, 0. This causes the ethernet driver to fail since devices on the mdio bus cannot share an address. Any address can be used for the switch, therefore, change the switch address to 0x1f.

dt-bindings: net: dsa: convert ocelot.txt to dt-schema

2022-09-20T14:46:09Z

Replace the free-form description of device tree bindings for VSC9959 and VSC9953 with a YAML formatted dt-schema description. This contains more or less the same information, but reworded to be a bit more succint.

dt-bindings: net: dsa: mt7530: stop requiring phy-mode on CPU ports

2022-09-20T00:59:52Z

dt-bindings: net: dsa: mt7530: replace label = "cpu" with proper checks

2022-09-20T00:59:52Z

The fact that some DSA device trees use 'label = "cpu"' for the CPU port is nothing but blind cargo cult copying. The 'label' property was never part of the DSA DT bindings for anything except the user ports, where it provided a hint as to what name the created netdevs should use. DSA does use the "cpu" port label to identify a CPU port in dsa_port_parse(), but this is only for non-OF code paths (platform data). The proper way to identify a CPU port is to look at whether the 'ethernet' phandle is present.

dt-bindings: net: dsa: mediatek,mt7530: update binding description

2022-08-31T05:46:55Z

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. Signed-off-by: Arınç ÜNAL Acked-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

Define acceptable phy-mode values for the CPU ports of mt7530 and mt7531 switches. Remove relevant information from the description of the binding. Signed-off-by: Arınç ÜNAL Reviewed-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

dt-bindings: net: dsa: mediatek,mt7530: update examples

2022-08-31T05:46:48Z

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. - 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.

dt-bindings: net: dsa: mediatek,mt7530: fix reset lines

2022-08-31T05:46:44Z

- Add description for reset-gpios. - Invalidate reset-gpios if mediatek,mcm is used. We cannot use multiple reset lines at the same time. - Invalidate mediatek,mcm if the compatible device is mediatek,mt7531. There is no multi-chip module version of mediatek,mt7531. - Require mediatek,mcm for mediatek,mt7621 as the compatible string is only used for the multi-chip module version of MT7530.
