[v5,00/13] further mt7988 devicetree work

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

This series continues mt7988 devicetree work

- Extend cpu frequency scaling with CCI
- GPIO leds
- Basic network-support (ethernet controller + builtin switch + SFP Cages)

sorry for confusion about irq-count and names, i tried to upstream only the needed parts.
I got the information that reserved irqs can be freely used (and not "blocked") very late.

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

support interrupt-names is optional again as i re-added the reserved IRQs
(they are not unusable as i thought and can allow features in future)
https://patchwork.kernel.org/project/netdevbpf/patch/20250619132125.78368-2-linux@fw-web.de/

for SFP-Function (macs currently disabled):

PCS clearance which is a 1.5 year discussion currently ongoing

Daniel asked netdev for a way 2 go:
https://lore.kernel.org/netdev/aEwfME3dYisQtdCj@pidgin.makrotopia.org/

e.g. something like this (one of):
* https://patchwork.kernel.org/project/netdevbpf/patch/20250610233134.3588011-4-sean.anderson@linux.dev/ (v6)
* https://patchwork.kernel.org/project/netdevbpf/patch/20250511201250.3789083-4-ansuelsmth@gmail.com/ (v4)
* https://patchwork.kernel.org/project/netdevbpf/patch/ba4e359584a6b3bc4b3470822c42186d5b0856f9.1721910728.git.daniel@makrotopia.org/

and then dts nodes for sgmiisys+usxgmii+2g5 firmware

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

changes:
v5:
- add reserved irqs and change names
- update binding for 8 irqs with different names (rx,tx => fe1+fe2, rx-ringX => pdmaX)
  (dropped Robs RB due to this change again, sorry)

v4:
net-binding:
- allow interrupt names and increase max interrupts to 6 because of RSS/LRO interrupts
  (dropped Robs RB due to this change)

dts-patches:
- add interrupts for RSS/LRO and interrupt-names for ethernet node
- eth-reg and clock whitespace-fix
- comment for fixed-link on gmac0
- drop phy-mode properties as suggested by andrew
- drop phy-connection-type on 2g5 board
- reorder some properties
- update 2g5 phy node
- unit-name dec instead of hex to match reg property
- move compatible before reg
- drop phy-mode

v3:
- dropped patches already applied (SPI+thermal)
- added soc specific cci compatible (new binding patch + changed dts)
- enable 2g5 phy because driver is now merged
- add patch for cleaning up unnecessary pins
- add patch for gpio-leds
- add patch for adding ethernet aliases

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

No,this section only allows this property and it
 is not listed in required section and so an
 optional property. But if it is defined in
 devicetree it needs 1 to 8 items.
