[PATCH v3 06/13] PCI: dwc: host: Read num-lanes property before host_init()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Vendor-specific initialization needs this information so that
read it before host_init(). And then, we can assume that
dw_pcie_{ep,host}_init() gets the property so that dw_pcie_setup()
doesn't need to get it again.
