The PCIe controller on Spacemit K3 is almost a standard Synopsys
Designware PCIe IP with extra control and external MSI controller
(IMSIC).
Add binding and driver support for PCIe RC controller support on K3.
Changed from v2:
- https://lore.kernel.org/linux-pci/20260517014841.254085-1...
patch 2:
1. Use unify PCIe phy get/enable/exit function for both K1 and K3.
patch 3:
1. New patch for updating device id for both K1/K3
patch 5:
1. Reuse binding for spacemit,k1-pcie-host
patch 6:
1. Multiple cleanup for the logic already generalized in the previous
patches.
2. Use generic description for the Kconfig entry.
Changed from v1:
patch 1:
1. Remove post_init callback.
patch 2:
1. Fix devm_kmalloc_array arguments order and error check.
patch 3:
1. Apply Rob's tag.
2. Change check from oneOf to anyOf.
3. Fix spelling mistakes in commit message.
patch 4:
1. Add comment about PHY handle.
2. Remove interrupt "app".
3. Fix spelling mistakes in commit message.
patch 5:
1. Remove all logic related to link up interrupt.
2. Clean up all unused macros.
3. Fix devm_kmalloc_array arguments order and error check.
4. Remove unnecessary start_link logic.
5. Make all magic number as a macro.
6. Fix spelling mistakes in code and commit message.
