[PATCH v4 0/6] Support mt7531 on BPI-R2 Pro

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

This Series add Support for the mt7531 switch on Bananapi R2 Pro board.

This board uses port5 of the switch to conect to the gmac0 of the
rk3568 SoC.

Currently CPU-Port is hardcoded in the mt7530 driver to port 6.

Compared to v1 the reset-Patch was dropped as it was not needed and
CPU-Port-changes are completely rewriten based on suggestions/code from
Vladimir Oltean (many thanks to this).
In DTS Patch i only dropped the status-property that was not
needed/ignored by driver.

Due to the Changes i also made a regression test on mt7623 bpi-r2
(mt7623 soc + mt7530) and bpi-r64 (mt7622 soc + mt7531) with cpu-
port 6. Tests were done directly (ipv4 config on dsa user port)
and with vlan-aware bridge including vlan that was tagged outgoing
on dsa user port.

v4: 
- rebase on 5.19-rc1
- some changes in bindings-document and fix wrong squashing from v3

[PATCH v4 1/6] dt-bindings: net: dsa: convert binding for mediatek switches

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

Convert txt binding to yaml binding for Mediatek switches.

Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
---
v4:
- fix squash of port 5 as cpu-port
- drop type from interrupt-controller and add depency for this
- use ethernet-ports in examples
- drop address-/size-cells

v3:
- include standalone patch in mt7530 series
- drop some descriptions (gpio-cells,reset-gpios,reset-names)
- drop | from descriptions
- move patternProperties above allOf

v2:
- rename mediatek.yaml => mediatek,mt7530.yaml
- drop "boolean" in description
- drop description for interrupt-properties
- drop #interrupt-cells as requirement
- example: eth=>ethernet,mdio0=>mdio,comment indention
- replace 0 by GPIO_ACTIVE_HIGH in first example
- use port(s)-pattern from dsa.yaml
- adress/size-cells not added to required because this
  is defined at mdio-level inc current dts , not switch level

+description: |
+  Port 5 of mt7530 and mt7621 switch is muxed between:
+  1. GMAC5: GMAC5 can interface with another external MAC or PHY.
+  2. PHY of port 0 or port 4: PHY interfaces with an external MAC like 2nd GMAC
+     of the SOC. Used in many setups where port 0/4 becomes the WAN port.
+     Note: On a MT7621 SOC with integrated switch: 2nd GMAC can only connected to
+       GMAC5 when the gpios for RGMII2 (GPIO 22-33) are not used and not
+       connected to external component!
+
+  Port 5 modes/configurations:
+  1. Port 5 is disabled and isolated: An external phy can interface to the 2nd
+     GMAC of the SOC.
+     In the case of a build-in MT7530 switch, port 5 shares the RGMII bus with 2nd
+     GMAC and an optional external phy. Mind the GPIO/pinctl settings of the SOC!
+  2. Port 5 is muxed to PHY of port 0/4: Port 0/4 interfaces with 2nd GMAC.
+     It is a simple MAC to PHY interface, port 5 needs to be setup for xMII mode
+     and RGMII delay.
+  3. Port 5 is muxed to GMAC5 and can interface to an external phy.
+     Port 5 becomes an extra switch port.
+     Only works on platform where external phy TX<->RX lines are swapped.
+     Like in the Ubiquiti ER-X-SFP.
+  4. Port 5 is muxed to GMAC5 and interfaces with the 2nd GAMC as 2nd CPU port.
+     Currently a 2nd CPU port is not supported by DSA code.
+
+  Depending on how the external PHY is wired:
+  1. normal: The PHY can only connect to 2nd GMAC but not to the switch
+  2. swapped: RGMII TX, RX are swapped; external phy interface with the switch as
+     a ethernet port. But can't interface to the 2nd GMAC.
+
+    Based on the DT the port 5 mode is configured.
+
+  Driver tries to lookup the phy-handle of the 2nd GMAC of the master device.
+  When phy-handle matches PHY of port 0 or 4 then port 5 set-up as mode 2.
+  phy-mode must be set, see also example 2 below!
+  * mt7621: phy-mode = "rgmii-txid";
+  * mt7623: phy-mode = "rgmii";
+
+  CPU-Ports need a phy-mode property:
+    Allowed values on mt7530 and mt7621:
+      - "rgmii"
+      - "trgmii"
+    On mt7531:
+      - "1000base-x"
+      - "2500base-x"
+      - "sgmii"

-Mediatek MT7530 Ethernet switch
-================================
-
-Required properties:
-
-- compatible: may be compatible = "mediatek,mt7530"
-	or compatible = "mediatek,mt7621"
-	or compatible = "mediatek,mt7531"
-- #address-cells: Must be 1.
-- #size-cells: Must be 0.
-- mediatek,mcm: Boolean; if defined, indicates that either MT7530 is the part
-	on multi-chip module belong to MT7623A has or the remotely standalone
-	chip as the function MT7623N reference board provided for.
-
-If compatible mediatek,mt7530 is set then the following properties are required
-
-- core-supply: Phandle to the regulator node necessary for the core power.
-- io-supply: Phandle to the regulator node necessary for the I/O power.
-	See Documentation/devicetree/bindings/regulator/mt6323-regulator.txt
-	for details for the regulator setup on these boards.
-
-If the property mediatek,mcm isn't defined, following property is required
-
-- reset-gpios: Should be a gpio specifier for a reset line.
-
-Else, following properties are required
-
-- resets : Phandle pointing to the system reset controller with
-	line index for the ethsys.
-- reset-names : Should be set to "mcm".
-
-Required properties for the child nodes within ports container:
-
-- reg: Port address described must be 6 for CPU port and from 0 to 5 for
-	user ports.
-- phy-mode: String, the following values are acceptable for port labeled
-	"cpu":
-	If compatible mediatek,mt7530 or mediatek,mt7621 is set,
-	must be either "trgmii" or "rgmii"
-	If compatible mediatek,mt7531 is set,
-	must be either "sgmii", "1000base-x" or "2500base-x"
-
-Port 5 of mt7530 and mt7621 switch is muxed between:
-1. GMAC5: GMAC5 can interface with another external MAC or PHY.
-2. PHY of port 0 or port 4: PHY interfaces with an external MAC like 2nd GMAC
-   of the SOC. Used in many setups where port 0/4 becomes the WAN port.
-   Note: On a MT7621 SOC with integrated switch: 2nd GMAC can only connected to
-	 GMAC5 when the gpios for RGMII2 (GPIO 22-33) are not used and not
-	 connected to external component!
-
-Port 5 modes/configurations:
-1. Port 5 is disabled and isolated: An external phy can interface to the 2nd
-   GMAC of the SOC.
-   In the case of a build-in MT7530 switch, port 5 shares the RGMII bus with 2nd
-   GMAC and an optional external phy. Mind the GPIO/pinctl settings of the SOC!
-2. Port 5 is muxed to PHY of port 0/4: Port 0/4 interfaces with 2nd GMAC.
-   It is a simple MAC to PHY interface, port 5 needs to be setup for xMII mode
-   and RGMII delay.
-3. Port 5 is muxed to GMAC5 and can interface to an external phy.
-   Port 5 becomes an extra switch port.
-   Only works on platform where external phy TX<->RX lines are swapped.
-   Like in the Ubiquiti ER-X-SFP.
-4. Port 5 is muxed to GMAC5 and interfaces with the 2nd GAMC as 2nd CPU port.
-   Currently a 2nd CPU port is not supported by DSA code.
-
-Depending on how the external PHY is wired:
-1. normal: The PHY can only connect to 2nd GMAC but not to the switch
-2. swapped: RGMII TX, RX are swapped; external phy interface with the switch as
-   a ethernet port. But can't interface to the 2nd GMAC.
-
-Based on the DT the port 5 mode is configured.
-
-Driver tries to lookup the phy-handle of the 2nd GMAC of the master device.
-When phy-handle matches PHY of port 0 or 4 then port 5 set-up as mode 2.
-phy-mode must be set, see also example 2 below!
- * mt7621: phy-mode = "rgmii-txid";
- * mt7623: phy-mode = "rgmii";
-
-Optional properties:
-
-- gpio-controller: Boolean; if defined, MT7530's LED controller will run on
-	GPIO mode.
-- #gpio-cells: Must be 2 if gpio-controller is defined.
-- interrupt-controller: Boolean; Enables the internal interrupt controller.
-
-If interrupt-controller is defined, the following properties are required.
-
-- #interrupt-cells: Must be 1.
-- interrupts: Parent interrupt for the interrupt controller.
-
-See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional
-required, optional properties and how the integrated switch subnodes must
-be specified.

[PATCH v4 2/6] net: dsa: mt7530: rework mt7530_hw_vlan_{add,del}

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

Rework vlan_add/vlan_del functions in preparation for dynamic cpu port.

Currently BIT(MT7530_CPU_PORT) is added to new_members, even though
mt7530_port_vlan_add() will be called on the CPU port too.

Let DSA core decide when to call port_vlan_add for the CPU port, rather
than doing it implicitly.

We can do autonomous forwarding in a certain VLAN, but not add br0 to that
VLAN and avoid flooding the CPU with those packets, if software knows it
doesn't need to process them.

[PATCH v4 5/6] dt-bindings: net: dsa: make reset optional and add rgmii-mode to mt7531

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

A board may have no independent reset-line, so reset cannot be used
inside switch driver.

E.g. on Bananapi-R2 Pro switch and gmac are connected to same reset-line.

Resets should be acquired only to 1 device/driver. This prevents reset to
be bound to switch-driver if reset is already used for gmac. If reset is
only used by switch driver it resets the switch *and* the gmac after the
mdio bus comes up resulting in mdio bus goes down. It takes some time
until all is up again, switch driver tries to read from mdio, will fail
and defer the probe. On next try the reset does the same again.

Make reset optional for such boards.

Allow port 5 as cpu-port and phy-mode rgmii for mt7531.

- MT7530 supports RGMII on port 5 and RGMII/TRGMII on port 6.
- MT7531 supports on port 5 RGMII and SGMII (dual-sgmii) and
  SGMII on port 6.
