Subject[PATCH 1/2] mfd: Add s5m regulator operation mode
Date
This patch add variables for opmode of s5m series.
S5M series have 4 operation modes.
Off mode is always regulator off mode.
On mode is always regulator on mode.
Lowpower mode is that regualtor operate in low-power.
Suspend mode is that regulator operation depends on AP suspend mode.
