Subject: PCI: layerscape: Call dw_pcie_setup_rc() from ls_pcie_host_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a36deff6d13da8e146ad02cf38c0b81752efb305;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: layerscape: Call dw_pcie_setup_rc() from ls_pcie_host_init()

We called dw_pcie_setup_rc() from the ls1021a host init function, but not
from the common ls_pcie_host_init() function, so platforms other than
ls1021a still depended on initialization by the bootloader.

Call dw_pcie_setup_rc() from ls_pcie_host_init() to reduce dependencies on
the bootloader.
