From 6e802ef540e91642ae7eb8ea39af94db07e2c2c2 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Wed, 5 Aug 2020 22:44:26 +0530 Subject: [PATCH] ram: k3-j721e: Relax version checks for memory controller k3-j721e ddr driver sanity checks for product id and version number. Version number gets changed for every minor update in the IP. So discard the version check and just sanity check for product id.
