+Subject: [PATCH] media: ipu7: set CSI2 port count by hardware version
+
+IPU7 provides four CSI2 ports, while IPU7P5 and IPU8 provide three.
+The common platform data initialization currently uses the four-entry
+offset table for every hardware version, causing an invalid fourth CSI2
+entity to be registered on IPU7P5 and IPU8.
+
+Pass the PCI-selected hardware version to the platform data initializer
+and set the number of ports accordingly.
