This series continues mt7988 devicetree work

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

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/

needs change in mtk ethernet driver for the sram to be read from separate node:
https://patchwork.kernel.org/project/netdevbpf/patch/c2b9242229d06af4e468204bcf42daa1535c3a72.1751461762.git.daniel@makrotopia.org/

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/ (local)

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/

first PCS-discussion is here:

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:
v9:
- dropped patches already applied (cci,gpio-leds,unused pins)
- added patches to add RSS IRQs, IRQ-names and sram-node for mt7986
   note: mt7981 does not have a ethernet node yet
- set minItems for Filogic (MT798x) IRQs/Names to 8
   needed to update MT7986 binding example because of this
- add sram:false to non-Filogic SoCs

v8:
- splitted binding into irq-count and irq-names and updated description
- fixed typo in mt7621 section "interrupt-namess"
- splitted binding changes into fixes (mac) and additions (sram)
- dropped change of reg (simple count to description)
- change ethernet register size to 0x40000

v7:
- fixed rebasing error while splitting dt-binding patch

v6:
binding:
- split out the interrupt-names into separate patch
- update irq(name) min count to 4
- move interrupt-names up
- add sram-property
- drop second reg entry and minitems as there is only 1 item left

dts:
- fix whitespace-errors for pdma irqs (spaces vs. tabs)
- move sram from eth reg to own sram node (needs CONFIG_SRAM)

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
