pwm: Add PWM driver for HiSilicon BVT SOCs

2016-11-29T15:50:12+00:00

Add PWM driver for the PWM controller found on HiSilicon BVT SoCs such as Hi3519V100, Hi3516CV300, etc. The PWM controller is primarily in charge of controlling the P-Iris lens. Reviewed-by: Jiancheng Xue Signed-off-by: Jian Yuan Acked-by: Rob Herring Signed-off-by: Thierry Reding

pwm: Add support for Meson PWM Controller

2016-09-08T08:55:00+00:00

Add support for the PWM controller found in the Amlogic SoCs. This driver supports the Meson8b and GXBB SoCs. Signed-off-by: Neil Armstrong Tested-by: Martin Blumenstingl Tested-by: Jerome Brunet Signed-off-by: Thierry Reding

pwm: Add ChromeOS EC PWM driver

2016-07-25T08:40:41+00:00

Use the new ChromeOS EC EC_CMD_PWM_{GET,SET}_DUTY commands to control one or more PWMs attached to the Embedded Controller. Because the EC allows us to modify the duty cycle (as a percentage, where U16_MAX is 100%) but not the period, we assign the period a fixed value of EC_PWM_MAX_DUTY and reject all attempts to change it. This driver supports only device tree at the moment, because that provides a very flexible way of describing the relationship between PWMs and their consumer devices (e.g., backlight). On a non-DT system, we'll probably want to use the non-GENERIC addressing (i.e., we'll need to make special device instances that will use EC_PWM_TYPE_KB_LIGHT or EC_PWM_TYPE_DISPLAY_LIGHT), as well as the relatively inflexible pwm_lookup infrastructure for matching devices. Defer that work for now. Signed-off-by: Brian Norris Signed-off-by: Thierry Reding

pwm: Add a driver for the STMPE PWM

2016-07-11T10:49:29+00:00

This adds a driver for the PWM block found in chips of the STMPE 24xx series of multi-purpose I2C expanders. (I think STMPE means ST Microelectronics Multi-Purpose Expander.) This PWM was designed in accordance with Nokia specifications and is kind of weird and usually just switched between max and zero duty cycle. However it is indeed a PWM so it needs to live in the PWM subsystem. This PWM is mostly used for white LED backlight. Cc: Lee Jones Signed-off-by: Linus Walleij Signed-off-by: Thierry Reding

pwm: Add support for Broadcom iProc PWM controller

2016-07-11T10:49:25+00:00

Add support for the PWM controller present in Broadcom's iProc family of SoCs. It has been tested on the Northstar+ bcm958625HR board. Signed-off-by: Yendapally Reddy Dhananjaya Reddy [thierry.reding@gmail.com: bunch of coding style fixes, cleanups] Signed-off-by: Thierry Reding

pwm: rcar: Depend on ARCH_RENESAS instead of ARCH_SHMOBILE

2016-03-23T16:11:44+00:00

This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

pwm: Add PWM driver for OMAP using dual-mode timers

2015-12-16T16:25:37+00:00

Adds support for using a OMAP dual-mode timer with PWM capability as a Linux PWM device. The driver controls the timer by using the dmtimer API. Add a platform_data structure for each pwm-omap-dmtimer nodes containing the dmtimers functions in order to get driver not rely on platform specific functions.
