The patches for this release cycle include various enhancements (device tree support, better compile coverage, ...) for existing drivers. There is a new driver for Atmel SoCs. Various drivers as well as the sysfs support received minor fixes and cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJS5m3bAAoJEN0jrNd/PrOhukQP/RdjGTUc8McrOt6pU20xKedI Sg2HfA77ODWb1T8iigO31qOfCzEhtpl15AZ9kpj6sgLP17PQAlMBQWxQO9iHwRIv GSGCW8RoWq1yvMImBn6LswR6a+aczsbI46z9kMvBGAsl58AETjR82dxH/nuJ6CVw cTUIaysmnOhDCidPBSQ2JG/TrmAqhM1wmaixv/39LtIt3pFC5XKoj5rQqPlLKVrZ r87ZvwKdoX9z87L1gDOxybGOhcKJOKU8Qc8MlQjYzIUzwd91V7fsGF+98RB7e1k2 +I/U0YYRFVfLIc2xxHtQZe80khhWTAOEkzvVOS7jgoXI41AlIlT6rOQnRCuMRniv YfPTMAQDln+npDEZ4xgdB6qUHIUtduNm2sfL6hWox8xG3Z8Wk5b2IlyBx+kwhSwY MiM6UZjuENi+XjO/Ea+oJtD6CJ+U48g++mrQhB+BY1IzmEmIeMH6Qut5I0grotjm qgjw+hEoFL9lJ190OXM9Fxu8aoDcGCIWS/UtXTG8q+V/jBmMeBvqj2jscnrMsZXF 3CTpIquKIHe83A8CLdD0AXauE4TJ/8Eh0zY+jEJzBNDgIFkqZJPIVrmwPgMCFz5O 2Vux3WDxIqXDYJ1RjKeNGUFEfnRPa1PUqc2un9512xJkthXQD4EYE9/P+/MOVGXX UJoi2MMv4Cmkbs+bMTns =Rq3R -----END PGP SIGNATURE----- Merge tag 'pwm/for-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm changes from Thierry Reding: "The patches for this release cycle include various enhancements (device tree support, better compile coverage, ...) for existing drivers.

bool "Pulse-Width Modulation (PWM) Support"
|
|
help
|
|
Generic Pulse-Width Modulation (PWM) support.
|
|
|
|
In Pulse-Width Modulation, a variation of the width of pulses
|
|
in a rectangular pulse signal is used as a means to alter the
|
|
average power of the signal. Applications include efficient
|
|
power delivery and voltage regulation. In computer systems,
|
|
PWMs are commonly used to control fans or the brightness of
|
|
display backlights.
|
|
|
|
This framework provides a generic interface to PWM devices
|
|
within the Linux kernel. On the driver side it provides an API
|
|
to register and unregister a PWM chip, an abstraction of a PWM
|
|
controller, that supports one or more PWM devices. Client
|
|
drivers can request PWM devices and use the generic framework
|
|
to configure as well as enable and disable them.
|
|
|
|
This generic framework replaces the legacy PWM framework which
|
|
allows only a single driver implementing the required API. Not
|
|
all legacy implementations have been ported to the framework
|
|
yet. The framework provides an API that is backward compatible
|
|
with the legacy framework so that existing client drivers
|
|
continue to work as expected.
|
|
|
|
If unsure, say no.
