+Subject: [PATCH] fsl/fman: backup and restore ICID registers
+
+During probing, FMAN is reset thus losing all its register
+settings. Backup port ICID registers before reset and restore
+them after, similarly to how it's done on powerpc / PAMU based
+platforms.
+This also has the side effect of disabling the old code path
+(liodn backup/restore handling) that obviously make no sense
+in the context of SMMU on ARMs.
