[PATCH v5 0/2] PCI: mediatek: Add support for EcoNet SoCs

[Caleb James DeLisle <cjd@cjdns.fr>]

Add EcoNet EN7528 (and EN751221) PCIe support.

Changes from v4:
* Fixed missing Acked-by
* Rebased to 66672af7a095d89f082c5327f3b15bc2f93d558e
* v4: https://lore.kernel.org/linux-mips/20260404182854.2183651-1-cjd@cjdns.fr/

Changes from v3:
* s/initiallized/initialized/
* Use PCIE_T_PVPERL_MS for sleep time
* Use PCI_PM_D3COLD_WAIT for startup wait time
* Clarify comment "Activate INTx interrupts"
* Add MTK_PCIE_RETRAIN quirk for devices which require link re-train
* Do not retrain *all* bridges, only root bridge
* Better comments and logging in retraining logic
* v3: https://lore.kernel.org/linux-mips/20260320094212.696671-1-cjd@cjdns.fr/

Changes from v2:
* mediatek-pcie.yaml -> s/power-domain/power-domains/ and drop example
* Patch 3 dropped as it has been applied (Thanks!)
* v2: https://lore.kernel.org/linux-mips/20260316155157.679533-1-cjd@cjdns.fr/

Changes from v1:
* mediatek-pcie.yaml slot0 needs device-type = "pci", fix dt_binding_check
Link: https://lore.kernel.org/linux-mips/177334026016.3889069.9474337544951486443.robh@kernel.org
* v1: https://lore.kernel.org/linux-mips/20260312165332.569772-1-cjd@cjdns.fr/

This was split from a larger PCIe patchset which crossed multiple
subsystems. I'm not labeling this a v3 because it's a new patchset, but
I'm keeping the historical record anyway.

Changes from econet-pcie v2:
* mediatek-pcie.yaml add missing constraints to PCI node properties
* econet-pcie v2: https://lore.kernel.org/linux-mips/20260309131818.74467-1-cjd@cjdns.fr

Changes from econet-pcie v1:
* pcie-mediatek.c Exclude pcie_retrain_link() when building as a module
* econet-pcie v1: https://lore.kernel.org/linux-mips/20260303190948.694783-1-cjd@cjdns.fr/
