- 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.
