[PATCH v7 00/14] further mt7988 devicetree work

[Frank Wunderlich <linux@fw-web.de>]

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

Sorry messed up the rebase in v6 somehow.

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/566ca90fc59ad0d3aff8bc8dc22ebaf0544bce47.1751072868.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/

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/

full usxgmii driver:

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:
v7:
- squashed first 2 v6 patches as they should to have interrupt-names and mt7988
  parts separated

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
