+Subject: [PATCH 2/2] ARM: OMAP2+: omap_hwmod: Add context ops to am43xx
+ soc_ops
+
+AM43XX contains PRM_*_CONTEXT registers like OMAP4 did to track loss
+of context in modules so utilize the same soc_ops present for OMAP4.
+
+Certain drivers use the context loss count to determine if context was
+truly lost during a suspend operation to decide whether or not a
+context restore is truly necessary. Without this, some drivers may
+choose not to restore context when they have actually lost it and fail
+to properly resume.
