2014-07-28gpio: split gpiod board registration into machine headerLinus Walleij
As per example from the regulator subsystem: put all defines and functions related to registering board info for GPIO descriptors into a separate <linux/gpio/machine.h> header.

2014-04-23ASoC: qi_lb60: Use GPIO descriptor APILars-Peter Clausen
The new GPIO descriptor API is now the preferred way for handling GPIOs. It also allows us to separate the platform depended code from the platform independent code (Which will make it possible to increase build test coverage of the platform independent code).

2012-07-23MIPS: JZ4740: reset: Initialize hibernate wakeup counters.Maarten ter Huurne
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.
