-Subject: [PATCH 14/21] MIPS: JZ4740: reset: Initialize hibernate wakeup
- counters.
-
-In hibernation mode only the wakeup logic and the RTC are left running,
-so this is what users perceive as power down.
-
-If the counters are not initialized, the corresponding pin (typically
-connected to the power button) has to be asserted for two seconds
-before the device wakes up. Most users expect a shorter wakeup time.
-
-I took the timing values of 100 ms and 60 ms from BouKiCHi's patch for
-the Dingoo A320 kernel.
