[PATCH v1 00/14] further mt7988 devicetree work

[Frank Wunderlich]

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

This series continues mt7988 devicetree work

- Add SPI with BPI-R4 nand to reach eMMC
- Add thermal protection (fan+cooling-points)
- Extend cpu frequency scaling with CCI
- Basic network-support (ethernet controller + builtin switch + SFP Cages)

depencies (i hope this list is complete and latest patches/series linked):

"Add Bananapi R4 variants and add xsphy" (reviewed, but not yet applied):
https://patchwork.kernel.org/project/linux-mediatek/list/?series=955733

"net: phy: mediatek: do not require syscon compatible for pio property":
https://patchwork.kernel.org/project/netdevbpf/patch/20250510174933.154589-1-linux@fw-web.de/
for phy led function (RFC not yet reviewed, resent without RFC)

for 2.5g phy function (currently disabled):
- net: ethernet: mtk_eth_soc: add support for MT7988 internal 2.5G PHY (already merged to 6.15-net-next)
- net: phy: mediatek: add driver for built-in 2.5G ethernet PHY on MT7988
  https://patchwork.kernel.org/project/netdevbpf/patch/20250219083910.2255981-4-SkyLake.Huang@mediatek.com/
  requested updated patch due to comments

for SFP-Function (macs currently disabled):

PCS clearance which is a 1.5 year discussion currently ongoing

e.g. something like this (one of):
* https://patchwork.kernel.org/project/netdevbpf/patch/20250510102348.14134-4-ansuelsmth@gmail.com/ 
  (changes requested, but no comment on the pcs part)
* https://patchwork.kernel.org/project/netdevbpf/patch/20250415193323.2794214-3-sean.anderson@linux.dev/
  (changes requested)
* https://patchwork.kernel.org/project/netdevbpf/patch/ba4e359584a6b3bc4b3470822c42186d5b0856f9.1721910728.git.daniel@makrotopia.org/

full usxgmii driver:
https://patchwork.kernel.org/project/netdevbpf/patch/07845ec900ba41ff992875dce12c622277592c32.1702352117.git.daniel@makrotopia.org/

first PCS-discussion is here:
https://patchwork.kernel.org/project/netdevbpf/patch/8aa905080bdb6760875d62cb3b2b41258837f80e.1702352117.git.daniel@makrotopia.org/

and then dts nodes for sgmiisys+usxgmii

when above depencies are solved the mac1+2 can be enabled and 2.5G phy and SFP slots will work.

[PATCH v1 05/14] arm64: dts: mediatek: mt7988: move uart0 and spi1 pins to soc dtsi

[Frank Wunderlich]

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

In order to use uart0 or spi1 there is only 1 possible pin definition
so move them to soc dtsi to reuse them in other boards and avoiding
conflict if defined twice.

Does phy-mode internal and fixed-link used together make any sense?
Please could you explain this.

I would expect the label to be in the board .dts file, since it is a
board property, not a SoC property.

Ah, i got that wrong, sorry.

What i don't know about here is if you should be defining your own
ds-port binding, or taking the existing binding and add a constraint.

Hi Andrew

thank you for first review.

this patch is only for allowing the phy-mode 'internal' and corrects the wrong mapping to mt7530-das-port which allows rgmii and sgmii which are invalid on mt7530.
i splitted the changes in binding to not squash different changes.

the phys with leds are on the builtin mt7530 internal mdio-bus which i add in patch 3.

i will move that into the board dtsi file in v2 because "normal" bpi-r4 and 2g5 variant are same here.

Maybe you just need to expand the commit message? What does this .dtsi
actually represent? The SoC, or what is common across a number of
boards?

mt7988a.dtsi represents the SoC, and thus there shouldn't be any
labels assigned to the DSA ports.

In case of the BananaPi R4 there are two different boards, one with 2x
SFP+ and one with 1x SFP+ + 1x 2500Base-T (with PoE-in), hence there is
a dtsi files for all the parts shared among the two boards. I suppose
Frank meant to move the labels to that board dtsi file, and that's
correct imho as the labels of the 1G switch ports are the same on BPi-R4
and BPi-R4-PoE.

This should become an items list, with an explanation of what each of

Hi,

the fixed link is used to bring up the mac and switch cpu port up with 
the right settings.
Of course we can hardcode it in driver for mt7988, but driver already 
supports the generic
definition via devicetree. So imho adding driver code for whats already 
supported via devicetree
does not make sense for me and devicetree shows the right settings 
(speed,duplex,flow control) without digging in the driver code.

e.g. we could disable flow-control there (but it causes retransmitts) 
without changing driver.

Imho this is the cleanest way without adding unnecessary driver code and 
SoC conditions and
devicetree describes hardware ;).

regards Frank

I would change to this

  reg:
    items:
      - description: Register for accessing the MACs.
      - description: SoC internal SRAM used for DMA operations.
    minItems: 1

Would this be OK this way?

You also shouldn't need to set maxItems here, since the list has 2 items
total.

no, i only tried to stay close to definition in mdio.yaml ;) there are some mt7988 boards floating around
where i do not know the dts. But i can make only "mdio" to be changed later if needed.

ok, then i need to add 'mediatek,pio' subproperty in next round...would be ok in this way?

  "^mdio(-bus)?$":
    $ref: /schemas/net/mdio.yaml#
    unevaluatedProperties: false

    properties:
      mediatek,pio:
        $ref: /schemas/types.yaml#/definitions/phandle
        description:
          Phandle pointing to the mediatek pinctrl node.
