Subject: [PATCH 115/115] PCI: layerscape: call dw_pcie_setup_rc() in host
|
||
|
|
initialization
|
||
|
|
|
||
|
|
A previous patch moved some Root Complex programming from
|
||
|
|
dw_pcie_host_init() to dw_pcie_setup_rc() where it belongs,
|
||
|
|
while the pci-layerscape driver didn't call dw_pcie_setup_rc()
|
||
|
|
anywhere after that. This patch is to add dw_pcie_setup_rc()
|
||
|
|
calling in layerscape host initialization to fix ls1012a pci
|
||
|
|
issue caused by that patch.
|
||
|
|
|
||
|
|
Fixes: c49b76f3c613("PCI: designware: Move Root Complex setup
|
||
|
|
code to dw_pcie_setup_rc()")
