[PATCH v5 0/8] arm64: dts: mediatek: Add Openwrt One AP functionality

[Sjoerd Simons <sjoerd@collabora.com>]

Significant changes in V5:
  * Rebase against linux v6.19-rc2, dropping merged patches
  * Drop note about disable pci_aspm in cover letter, not required anymore
Significant changes in V4:
  * Drop patches that were picked up
  * Improve mediatek,net dt bindings:
    - Move back to V2 version (widening global constraint, constraining
      per compatible)
    - Ensure all compatibles are constraint in the amount of WEDs (2 for
      everything apart from mt7981). Specifically adding constraints for
      mediatek,mt7622-eth and ralink,rt5350-eth
Significant changes in V3:
  * Drop patches that were picked up
  * Re-order patches so changes that don't require dt binding changes
    come first (Requested by Angelo)
  * Specify drive power directly rather then using MTK_DRIVE_...
  * Simply mediatek,net binding changes to avoid accidental changes to
    other compatibles then mediatek,mt7981-eth
Significant changes in V2:
  * https://lore.kernel.org/lkml/20251016-openwrt-one-network-v1-0-de259719b6f2@collabora.com/
  * Only introduce labels in mt7981b.dtsi when required
  * Switch Airoha EN8811H phy irq to level rather then edge triggered
  * Move uart0 pinctrl from board dts to soc dtsi
  * Only overwrite constraints with non-default values in MT7981 bindings
  * Make SPI NOR nvmem cell labels more meaningfull
  * Seperate fixing and disable-by-default for the mt7981 in seperate
    patches

This series add various peripherals to the Openwrt One, to make it
actually useful an access point:

* Pcie express (tested with nvme storage)
* Wired network interfaces
* Wireless network interfaces (2.4g, 5ghz wifi)
* Status leds
* SPI NOR for factory data

Unsurprisingly the series is a mix of dt binding updates, extensions of
the mt7981b and the openwrt one dtb. All driver support required is
already available.

Sadly during testing i've found various quirks requiring kernel
arguments. Documenting those here both as note to self and making it
easier for others to test :)

* fw_devlink=permissive: the nvmem fixed-layout doesn't create a layout
  device, so doesn't trigger fw_devlink
* clk_ignore_unused: Needed when building CONFIG_NET_MEDIATEK_SOC as a
  module. If the ethernet related clocks (gp1/gp2) get disabled the
  mac ends up in a weird state causing it not to function correctly.

Patches are against linux v6.19-rc2
