No, you don't get an instance ID. Drop the property and look how other
bindings encoded it (not sure about the purpose and you did not explain
it, so cannot advise).
Dear Krzysztof,
Sorry, I missed your reply to this in the previous email.
Because our Root Port driver needs to support 5 PCIe ports, and the
register configuration and offset of each port are different, it is
necessary to know which port it is currently. Perhaps I can use the
following method and then delete this attribute.
aliases {
......
pcie_rc0 = &pcie_x8_rc;
pcie_rc1 = &pcie_x4_rc;
pcie_rc2 = &pcie_x2_rc;
pcie_rc3 = &pcie_x1_0_rc;
pcie_rc4 = &pcie_x1_1_rc;
id = of_alias_get_id(dev->of_node, "pcie_rc");
Best regards,
Hans
