Subject: Re:[PATCH v7 08/17] ACPI: pci_link: Clear the dependencies after probe

Hi, sunilvl

Based on the above patch, I understand that you previously resolved dependencies between Link devices and PCI Host Bridges by calling acpi_dev_clear_dependencies(device). I would like to ask: on RISC‑V platforms, if we need to manage dependencies between multiple PCI Host Bridges, could this be addressed by adding a call to acpi_dev_clear_dependencies(device) at the end of the acpi_pci_root_add enumeration function?

Initialization order dependencies can be defined via the ACPI _DEP method in the DSDT. For example, if host bridge B depends on host bridge A, bridge B should not be enumerated until bridge A is fully initialized.

Best regards,
Yuye
