2015-04-11powerpc/tm: Abort syscalls in active transactionsSam bobroff1-16/+16
This patch changes the syscall handler to doom (tabort) active transactions when a syscall is made and return immediately without performing the syscall. Currently, the system call instruction automatically suspends an active transaction which causes side effects to persist when an active transaction fails. This does change the kernel's behaviour, but in a way that was documented as unsupported. It doesn't reduce functionality because syscalls will still be performed after tsuspend. It also provides a consistent interface and makes the behaviour of user code substantially the same across powerpc and platforms that do not support suspended transactions (e.g. x86 and s390). Performance measurements using http://ozlabs.org/~anton/junkcode/null_syscall.c indicate the cost of a system call increases by about 0.5%.

2015-04-10clk: Add PWM clock driverPhilipp Zabel1-0/+26
Some board designers, when running out of clock output pads, decide to (mis)use PWM output pads to provide a clock to external components. This driver supports this practice by providing an adapter between the PWM and clock bindings in the device tree. As the PWM bindings specify the period in the device tree, this is a fixed clock.

2015-04-10i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recoveryGrygorii Strashko1-0/+3
Having a board where the I2C bus locks up occasionally made it clear that the bus recovery in the i2c-davinci driver will only work on some boards, because on regular boards, this will only toggle GPIO lines that aren't muxed to the actual pins. The I2C controller on SoCs like da850 (and da830), Keystone 2 has the built-in capability to bit-bang its lines by using the ICPFUNC registers of the i2c controller. Implement the suggested procedure by toggling SCL and checking SDA using the ICPFUNC registers of the I2C controller when present. Allow platforms to indicate the presence of the ICPFUNC registers with a has_pfunc platform data flag and add optional DT property "ti,has-pfunc" to indicate the same in DT.

2015-04-09iio: mlx90614: Add power managementVianney le Clément de Saint-Marcq1-0/+9
Add support for system sleep and runtime power management. To wake up the device, the SDA line should be held low for at least 33ms while SCL is high. As this is not possible using the i2c API (and not supported by all i2c adapters), a GPIO connected to the SDA line is needed. The GPIO is named "wakeup" and can be specified in a device tree with the "wakeup-gpios" binding. If the wake-up GPIO is not given, disable power management for the device. Entering sleep requires an SMBus byte access, hence power management is also disabled if byte access is not supported by the adapter.

2015-04-09iio: core: Introduce IIO_CHAN_INFO_CALIBEMISSIVITYVianney le Clément de Saint-Marcq1-0/+11
Contact-less IR temperature sensors measure the temperature of an object by using its thermal radiation. Surfaces with different emissivity ratios emit different amounts of energy at the same temperature. IIO_CHAN_INFO_CALIBEMISSIVITY allows the user to inform the sensor of the emissivity of the object in front of it, in order to effectively measure its temperature. A device providing such setting is Melexis's MLX90614: http://melexis.com/Assets/IR-sensor-thermometer-MLX90614-Datasheet-5152.aspx.
