Subject: [PATCH 1/2] mfd: Add s5m regulator operation mode
Date: Fri, 09 Mar 2012 17:53:53 +0900 [thread overview]
Message-ID: <06ac01ccfdd2$27701c80$76505580$@com> (raw)
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.
