Subject: [PATCH v2 00/14] further mt7988 devicetree work

From: Frank Wunderlich <frank-w@...lic-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, partially 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/20250516102327.2014531-3-SkyLake.Huang@mediatek.com/ (v4)

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/20250511201250.3789083-4-ansuelsmth@gmail.com/ (v4)
* https://patchwork.kernel.org/project/netdevbpf/patch/20250512161013.731955-4-sean.anderson@linux.dev/ (v4)
* 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/SFP slots will work.

changes:
v2:
  - change reg to list of items in eth binding
  - changed mt7530 binding:
    - unevaluatedProperties=false
    - mediatek,pio subproperty
    - from patternProperty to property
  - board specific properties like led function and labels moved to bpi-r4 dtsi
