e8af7c08 - pwm: Strengthen dependency for PWM_SIFIVE

Mon, 27 Jan 2025 10:50:01 +0000

pwm: Strengthen dependency for PWM_SIFIVEBack when the sifive pwm driver was added there was no symbol for sifiveSoCs yet. Today there is ARCH_SIFIVE however. Let PWM_SIFIVE depend onthat to ensure the driver is only build for platforms where there is achance that the hardware is available.Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20250127105001.587610-2-u.kleine-koenig@baylibre.comSigned-off-by: Uwe Kleine-König List of files: /linux-6.15/drivers/pwm/Kconfig

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/Kconfig

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/Kconfig

mfd: rz-mtu3: Link time dependenciesThe new set of drivers for RZ/G2L MTU3a tries to enable compile-testing theindividual client drivers even when the MFD portion is disabled but gets itwrong, causing a link failure when the core is in a loadable module but theother drivers are built-in:x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply':pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write'x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable'arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get':rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read'It seems better not to add the extra complexity here but instead just usea normal hard dependency, so remove the #else portion in the header alongwith the "|| COMPILE_TEST". This could also be fixed by having slightly moreelaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper,but in practice it's already possible to compile-test all these driversby enabling the mtd portion.Fixes: 254d3a727421c ("pwm: Add Renesas RZ/G2L MTU3a PWM driver")Fixes: 0be8907359df4 ("counter: Add Renesas RZ/G2L MTU3a counter driver")Fixes: 654c293e1687b ("mfd: Add Renesas RZ/G2L MTU3a core driver")Signed-off-by: Arnd Bergmann Acked-by: Thierry Reding Reviewed-by: Biju Das Link: https://lore.kernel.org/r/20230719090430.1925182-1-arnd@kernel.orgSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/pwm/Kconfig

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/Kconfig
