Merge tag 'pwm/for-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

2014-04-06T01:32:31+00:00

Pull pwm changes from Thierry Reding: "The legacy HAVE_PWM Kconfig symbol is finally being retired. Thanks a lot to Sascha Hauer for doing that. Three new drivers are added: Freescale FTM, Cirrus Logic CLPS711X and Intel Low Power Subsystem. An assortment of fixes and cleanups rounds things off for this release cycle" * tag 'pwm/for-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: pwm: pxa: Constify OF match table pwm: pxa: Fix typo "pwm" -> "PWM" Revert "pwm: pxa: Use of_match_ptr()" pwm: add support for Intel Low Power Subsystem PWM pwm: Add CLPS711X PWM support pwm: atmel: correct CDTY calculation pwm: atmel: Fix polarity handling Documentation: Add device tree bindings for Freescale FTM PWM. pwm: Add Freescale FTM PWM driver support pwm: pxa: Use of_match_ptr() pwm: samsung: Use SIMPLE_DEV_PM_OPS macro pwm: renesas-tpu: Add dependency on HAS_IOMEM pwm: Remove obsolete HAVE_PWM Kconfig symbol

pwm: pxa: Constify OF match table

2014-04-01T12:06:43+00:00

The table is never modified and all OF functions that use it take a const struct of_device_id *. Signed-off-by: Thierry Reding

pwm: pxa: Fix typo "pwm" -> "PWM"

2014-04-01T12:04:59+00:00

Being an abbreviation, PWM should always be capitalized in prose. Signed-off-by: Thierry Reding

Revert "pwm: pxa: Use of_match_ptr()"

2014-04-01T12:01:32+00:00

This reverts commit 8468949cddcdbb1b1b1bc552aefceb252078ceb1. The OF match table dummy for non-OF configurations cannot be removed because it is still used by the pxa_pwm_get_id_dt() function. Signed-off-by: Thierry Reding

pwm: add support for Intel Low Power Subsystem PWM

2014-04-01T10:03:40+00:00

Add support for Intel Low Power I/O subsystem PWM controllers found on Intel BayTrail SoC. Signed-off-by: Mika Westerberg Signed-off-by: Chew, Kean Ho Signed-off-by: Chang, Rebecca Swee Fun Signed-off-by: Chew, Chiau Ee Signed-off-by: Thierry Reding

pwm: Add CLPS711X PWM support

2014-03-18T20:15:16+00:00

Add a new driver for the ARM CLPS711X Pulse Width Modulator (PWM) interface. This CPU contain two 4-bit PWM outputs with constant period, based on CPU PLL frequency. PWM polarity is determined by hardware by power on reset. Signed-off-by: Alexander Shiyan Signed-off-by: Thierry Reding

pwm: atmel: correct CDTY calculation

2014-03-18T19:47:48+00:00

From the datasheet, the actual duty cycle is: (period - (1 / clk) * CDTY) / period This actually correct the polarity of the PWM and solves the issue that pwm-leds exhibits: when setting a duty cycle of 0 and then disabling a channel, the level was wrong (1 when the polarity was normal and 0 when the polarity was inversed).

pwm: atmel: Fix polarity handling

2014-03-18T19:47:31+00:00

When atmel_pwm_config() calculates and then sets the prescaler, it is overwriting the channel's CMR register so we are losing the CPOL configuration. As atmel_pwm_config() is always called before enabling a channel, inverting the polarity doesn't work. Fix that by reading CMR first and only overwriting the prescaler bits.

pwm: Add Freescale FTM PWM driver support

2014-03-18T17:01:56+00:00

The FTM PWM device can be found on Vybrid VF610 Tower and Layerscape LS-1 SoCs. Signed-off-by: Xiubo Li Signed-off-by: Alison Wang Signed-off-by: Jingchang Lu Reviewed-by: Sascha Hauer Reviewed-by: Yuan Yao Signed-off-by: Thierry Reding
