2015-12-15pm-imx6.c: fix power off by stop modeColibri_iMX6_LinuxImageV2.5Beta3_20151215Apalis_iMX6_LinuxImageV2.5Beta3_20151215Max Krummenacher
With the 3.14.28 release of the kernel imx6_stop_mode_poweroff() does not enter stop mode. Thus the function does not switch of power but returns. This seems to be caused by the second processor which has been stopped. Set the WFI event mask for the stopped processor works around the issue.

2015-12-15gpio: generic: clamp retured value to [0,1]Linus Walleij
The generic GPIO would return 0 for low generic GPIO, and something != 0 for high GPIO. Let's make this sane by clamping the returned value to [0,1].

2015-12-02ARM: LLVMLinux: Change "extern inline" to "static inline" in glue-cache.hBehan Webster
With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function). "static inline" is the correct choice instead.

2015-11-04ASoC: sgtl5000: Fix the cache handlingFabio Estevam
Since commit e5d80e82e32e (ASoC: sgtl5000: Convert to use regmap directly) a kernel oops is observed after a suspend/resume sequence. The kernel oops happens inside sgtl5000_restore_regs() as codec->reg_cache is no longer a valid pointer. Add the remaining register entries into sgtl5000_reg_defaults[] and remove sgtl5000_restore_regs() completely, which allows suspend/resume to work fine and make the code simpler. Tested on a im53-qsb board.

2015-11-03input: touchscreen: fusion: implement multitouch with slot handlingStefan Agner
According to multi-touch-protocol.txt the kernel knows two type of devices: - Type A: devices which provide anonymous contacts - Type B: devices which are capable of tracking individual contacts The Fusion touch screen is a Type B device: The Touch ID field allows to differentiate between 2 different fingers. This updates the driver to properly allocate a slot for each identified contact and use the helper functions available from the input core system.

2015-09-18extcon: usb-gpio: Introduce gpio usb extcon driverRoger Quadros
This driver observes the USB ID pin connected over a GPIO and updates the USB cable extcon states accordingly. The existing GPIO extcon driver is not suitable for this purpose as it needs to be taught to understand USB cable states and it can't handle more than one cable per instance. For the USB case we need to handle 2 cable states. 1) USB (attach/detach) 2) USB-HOST (attach/detach) This driver can be easily updated in the future to handle VBUS events in case it happens to be available on GPIO for any platform.
