Pull pwm updates from Thierry Reding: "This set of changes introduces the beginnings of a new API that's based around the concept of states that can be atomically applied. Drivers go to various lengths to implement something similar, which indicates that the core should really be providing the necessary framework. On top of that, there is a bit of cleanup as well as improved kerneldoc and integration into the device-drivers DocBook. Regarding drivers there is a new one for the NXP LPC18xx family of SoCs and a couple of fixes for existing drivers (pca9685, Broadcom Kona and Atmel HLCDC)" * tag 'pwm/for-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: ARM: at91: pwm: atmel-hlcdc: Add at91sam9n12 errata pwm: Add NXP LPC18xx PWM/SCT DT binding documentation pwm: NXP LPC18xx PWM/SCT driver pwm-pca9685: Support changing the output frequency pwm-pca9685: Fix several driver bugs pwm: kona: Modify settings application sequence pwm: pca9685: Drop owner assignment pwm: Add to device-drivers documentation pwm: Clean up kerneldoc pwm: Remove useless whitespace pwm: sysfs: Remove unnecessary padding pwm: sysfs: Properly convert from enum to string pwm: Make use of pwm_get_xxx() helpers where appropriate pwm: Add pwm_get_polarity() helper function pwm: Constify PWM device where possible pwm: Add the pwm_is_enabled() helper

pwm: NXP LPC18xx PWM/SCT driver

2015-09-09T13:00:33+00:00

This commit adds support for NXP LPC18xx PWM/SCT. NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State Configurable Timer (SCT) which can be configured as a Pulse Width Modulator. Other SoCs in that family may share the same hardware. The PWM supports a total of 16 channels, but only 15 can be simultaneously requested. There's only one period, global to all the channels, thus PWM driver will refuse setting different values to it, unless there's only one channel requested.

pwm: crc: Add Crystalcove (CRC) PWM driver

2015-07-21T07:22:23+00:00

The Crystalcove PMIC provides three PWM signals and this driver exports one of them on the BYT platform which is used to control backlight for DSI panel. This is platform device implementation of the drivers/mfd cell device for CRC PMIC.

pwm: Imagination Technologies PWM DAC driver

2015-01-30T11:16:04+00:00

The Pistachio SOC from Imagination Technologies includes a Pulse Width Modulation DAC which produces 1 to 4 digital bit-outputs which represent digital waveforms. These PWM outputs are primarily in charge of controlling backlight LED devices.

pwm: add support for atmel-hlcdc-pwm device

2014-11-17T11:20:17+00:00

The HLCDC IP available in some Atmel SoCs (i.e. at91sam9x5, at91sam9n12 or sama5d3 families for instance) provides a PWM device. This driver add support for a PWM chip exposing a single PWM device (which will most likely be used to drive a backlight device).

pwm: lpss: Properly split driver to parts

2014-08-22T22:25:47+00:00

The driver consists of core, PCI, and platform parts. It would be better to split them into separate files. The platform driver is now called pwm-lpss-platform. Thus, previously set CONFIG_PWM_LPSS=m is not enough to build it. But we are on the safe side since it seems no one from outside Intel is using it for now. While here, move to use macros module_pci_driver() and module_platform_driver().
