+Subject: [PATCH] PCI: qcom: Fixing broken pcie enumeration for 2_3_3 configs
+ ops
+
+PARF_SLV_ADDR_SPACE_SIZE_2_3_3 macro is used for IPQ8074 2_3_3 post_init.
+PCIe slave addr register offset is 0x358, but was wrongly changed to
+0x168 as a part of commit 39171b33f652 ("PCI: qcom: Remove PCIE20_ prefix
+from register definitions"). Fixing it, by using the right macro and remove
+the unused PARF_SLV_ADDR_SPACE_SIZE_2_3_3.
+
+Without this access to the registers of slave addr space like iATU etc
+are broken leading to pcie enumeration failure.
+
+Fixes: 39171b33f652 ("PCI: qcom: Remove PCIE20_ prefix from register definitions")
