Okay, so this looks slightly different than the outbound macro since it tak=
es
the register argument. In the case of outbound PCIE_GET_ATU_OUTB_UNR_REG_OF=
FSET
returns the offset which was used like
dw_pcie_write_dbi(pci, base, offset + reg, 0x4, val);

How should the value from PCIE_GET_ATU_INB_UNR_REG_ADDR be used?

Thanks
Kishon
