Add the device tree bindings document for the TI CPUFreq/OPP driver on AM33xx, AM43xx, DRA7xx, and AM57xx SoCs. The operating-points-v2 binding allows us to provide an opp-supported-hw property for each OPP to define when it is available. This driver is responsible for reading and parsing registers to determine which OPPs can be selectively enabled based on the specific SoC in use by matching against the opp-supported-hw data.

2017-02-04cpufreq: intel_pstate: Operation mode control from sysfsRafael J. Wysocki1-0/+15
Make it possible to change the operation mode of intel_pstate with the help of a new sysfs attribute called "status". There are three possible configurations that can be selected using this attribute: "off" - The driver is not in use at this time. "active" - The driver works as a P-state governor (default). "passive" - The driver works as a regular cpufreq one and collaborates with the generic cpufreq governors (it sets P-states as requested by those governors). [This is the same mode the driver can be started in by passing intel_pstate=passive in the kernel command line.] The current setting is returned by reads from this attribute. Writing one of the above strings to it changes the operation mode as indicated by that string, if possible. If HW-managed P-states (HWP) feature is enabled, it is not possible to change the driver's operation mode and attempts to write to this attribute will fail. Signed-off-by: Rafael J.

This patch just removes '.' character from the sysfs name of devfreq-event device as following. Usually, the subsystem uses the similiar naming style such as {framework name}{Number}. - old : /sys/class/devfreq-event/event.(X) - new : /sys/class/devfreq-event/event(X) And this patch initializes the value of 'event_no' with -1 in order to remove the unneeded operation (-1) when calling the atomic_inc_return(&event_no).

2017-01-25Documentation: devicetree: change the mediatek ethernet compatible stringJohn Crispin1-1/+1
When the binding was defined, I was not aware that mt2701 was an earlier version of the SoC. For sake of consistency, the ethernet driver should use mt2701 inside the compat string as this is the earliest SoC with the ethernet core. The ethernet driver is currently of no real use until we finish and upstream the DSA driver. There are no users of this binding yet. It should be safe to fix this now before it is too late and we need to provide backward compatibility for the mt7623-eth compat string.

2017-01-24Documentation: net: phy: improve explanation when to specify the PHY IDMartin Blumenstingl1-2/+3
The old description basically read like "ethernet-phy-idAAAA.BBBB" can be specified when you know the actual PHY ID. However, specifying this has a side-effect: it forces Linux to bind to a certain PHY driver (the one that matches the ID given in the compatible string), ignoring the ID which is reported by the actual PHY. Whenever a device is shipped with (multiple) different PHYs during it's production lifetime then explicitly specifying "ethernet-phy-idAAAA.BBBB" could break certain revisions of that device.

2017-01-24ARCv2: MCIP: Deprecate setting of affinity in Device TreeYuriy Kolerov1-0/+3
Ignore value of interrupt distribution mode for common interrupts in IDU since setting of affinity using value from Device Tree is deprecated in ARC. Originally it is done in idu_irq_xlate() function and it is semantically wrong and does not guaranty that an affinity value will be set properly. idu_irq_enable() function is better place for initialization of common interrupts. By default send all common interrupts to all available online CPUs. The affinity of common interrupts in IDU must be set manually since in some cases the kernel will not call irq_set_affinity() by itself: 1. When the kernel is not configured with support of SMP. 2. When the kernel is configured with support of SMP but upper interrupt controllers does not support setting of the affinity and cannot propagate it to IDU.
