Mon, 22 Jul 2024 12:11:00 +0000

pwm: adp5585: Add Analog Devices ADP5585 supportThe ADP5585 is a 10/11 input/output port expander with a built in keypadmatrix decoder, programmable logic, reset generator, and PWM generator.This driver supports the PWM function using the platform deviceregistered by the core MFD driver.The driver is derived from an initial implementation from NXP, availablein commit 113113742208 ("MLK-25922-1 pwm: adp5585: add adp5585 PWMsupport") in their BSP kernel tree.

7f61257c - pwm: Add GPIO PWM driver

Tue, 04 Jun 2024 21:00:41 +0000

pwm: Add GPIO PWM driverAdd a software PWM which toggles a GPIO from a high-resolution timer.This will naturally not be as accurate or as efficient as a hardwarePWM, but it is useful in some cases. I have for example used it forevaluating LED brightness handling (via leds-pwm) on a board where theLED was just hooked up to a GPIO, and for a simple verification of thetimer frequency on another platform.Since high-resolution timers are used, sleeping GPIO chips are notsupported and are rejected in the probe function.Signed-off-by: Vincent Whitchurch Co-developed-by: Stefan Wahren Signed-off-by: Stefan Wahren Co-developed-by: Linus Walleij Reviewed-by: Andy Shevchenko Signed-off-by: Linus Walleij Reviewed-by: Dhruva Gole Link: https://lore.kernel.org/r/20240604-pwm-gpio-v7-2-6b67cf60db92@linaro.orgSigned-off-by: Uwe Kleine-König List of files: /linux-6.15/drivers/pwm/Makefile

e9cc807f - pwm: Move contents of sysfs.c into core.c

Sun, 17 Mar 2024 10:40:34 +0000

pwm: Move contents of sysfs.c into core.cWith the upcoming restructuring having all in a single file simplifiesthings a bit. The relevant and somewhat visible changes are: - Some dropped prototypes from include/linux/pwm.h that were only necessary that core.c has a declaration of the symbols defined in sysfs.c. The respective functions are static now. - The pwm class now also exists if CONFIG_SYSFS isn't enabled. Having CONFIG_SYSFS is not very relevant today, but even without it the class and device stuff still provides lifetime tracking. - Both files had an initcall, these are merged into a single one now. Instead of a big #ifdef block for CONFIG_DEBUG_FS, a single if (IS_ENABLED(CONFIG_DEBUG_FS)) is used now. This increases compile coverage a bit and is a tad nicer on the eyes.Link: https://lore.kernel.org/r/9e2d39a5280d7dda5bfc6682a8aef510148635b2.1710670958.git.u.kleine-koenig@pengutronix.deSigned-off-by: Uwe Kleine-König List of files: /linux-6.15/drivers/pwm/Makefile

pwm: dwc: split pci out of core driverMoving towards adding non-pci support for the driver, move the pciparts out of the core into their own module. This is partly due tothe module_driver() code only being allowed once in a module and alsoto avoid a number of #ifdef if we build a single file in a systemwithout pci support.Signed-off-by: Ben Dooks Acked-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20230907161242.67190-2-ben.dooks@codethink.co.ukSigned-off-by: Uwe Kleine-König Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/pwm/Makefile

pwm: Add support for Xilinx AXI TimerThis adds PWM support for Xilinx LogiCORE IP AXI soft timers commonlyfound on Xilinx FPGAs. At the moment clock control is very basic: wejust enable the clock during probe and pin the frequency. In the future,someone could add support for disabling the clock when not in use.Some common code has been specially demarcated. While currently onlyused by the PWM driver, it is anticipated that it may be split off inthe future to be used by the timer driver as well.This driver was written with reference to Xilinx DS764 for v1.03.a [1].[1] https://www.xilinx.com/support/documentation/ip_documentation/axi_timer/v1_03_a/axi_timer_ds764.pdfSigned-off-by: Sean Anderson Acked-by: Michal Simek Reviewed-by: Uwe Kleine-König Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/pwm/Makefile
