+Subject: [PATCH 130/247] regulator: mcp16502: lpm pin can be optional on some
+ platforms
+
+On some platform (e.g. SAMA7G5) LPM pin should be optional as it can
+be controlled explicitly (via shutdown controller registers) in the
+platform specific power saving code to decrease the power consumption
+while suspended as this SoC pin may be connected to other devices that
+could take power saving actions based on its value.
