[PATCH] PCI: dra7xx: program outbound atu with correct address

Show all headers | View raw

From: Niklas Cassel <niklas.cassel@axis.com>

commit 1488aefa37a4 ("PCI: designware: Move Root Complex
setup code to dw_pcie_setup_rc()") broke dra7xx
by moving code from dw_pcie_host_init to dw_pcie_setup_rc.

Fix this by doing the cpu to bus calculation before calling
dw_pcie_setup_rc.
