+description: |
+  MStar/Sigmastar's Armv7 SoCs contain a region of registers that are
+  in the always on domain that the vendor code calls the "pmsleep" area.
+
+  This area contains registers and bits for a broad range of functionality
+  ranging from registers that control going into deep sleep to bits that
+  turn things like the internal temperature sensor on and off.
