e03724aac758f71c6cda208ea3d1afd0bbb6d9aa - pwm: Add Rust driver for T-HEAD TH1520 SoC

Thu, 16 Oct 2025 15:38:04 +0200

pwm: Add Rust driver for T-HEAD TH1520 SoCIntroduce a PWM driver for the T-HEAD TH1520 SoC, written in Rust andutilizing the safe PWM abstractions from the preceding commit.The driver implements the pwm::PwmOps trait using the modern waveformAPI (round_waveform_tohw, write_waveform, etc.) to support configurationof period, duty cycle, and polarity for the TH1520's PWM channels.Resource management is handled using idiomatic Rust patterns. The PWMchip object is allocated via pwm::Chip::new and its registration withthe PWM core is managed by the pwm::Registration RAII guard. Thisensures pwmchip_remove is always called when the driver unbinds,preventing resource leaks. Device managed resources are used for theMMIO region, and the clock lifecycle is correctly managed in thedriver's private data Drop implementation.The driver's core logic is written entirely in safe Rust, with no unsafeblocks, except for the Send and Sync implementations for the driverdata, which are explained in the comments.Reviewed-by: Elle Rhumsaa Signed-off-by: Michal Wilczynski Link: https://patch.msgid.link/20251016-rust-next-pwm-working-fan-for-sending-v16-4-a5df2405d2bd@samsung.comSigned-off-by: Uwe Kleine-König List of files: /linux/drivers/pwm/Makefile

pwm: Add support for RZ/G2L GPTRZ/G2L General PWM Timer (GPT) composed of 8 channels with 32-bit timer(GPT32E). It supports the following functions * 32 bits x 8 channels * Up-counting or down-counting (saw waves) or up/down-counting (triangle waves) for each counter. * Clock sources independently selectable for each channel * Two I/O pins per channel * Two output compare/input capture registers per channel * For the two output compare/input capture registers of each channel, four registers are provided as buffer registers and are capable of operating as comparison registers when buffering is not in use. * In output compare operation, buffer switching can be at crests or troughs, enabling the generation of laterally asymmetric PWM waveforms. * Registers for setting up frame cycles in each channel (with capability for generating interrupts at overflow or underflow) * Generation of dead times in PWM operation * Synchronous starting, stopping and clearing counters for arbitrary channels * Starting, stopping, clearing and up/down counters in response to input level comparison * Starting, clearing, stopping and up/down counters in response to a maximum of four external triggers * Output pin disable function by dead time error and detected short-circuits between output pins * A/D converter start triggers can be generated (GPT32E0 to GPT32E3) * Enables the noise filter for input capture and external trigger operationAdd basic pwm support for RZ/G2L GPT driver by creating separatelogical channels for each IOs.Signed-off-by: Biju Das Link: https://lore.kernel.org/r/20250226144531.176819-4-biju.das.jz@bp.renesas.comSigned-off-by: Uwe Kleine-König List of files: /linux/drivers/pwm/Makefile

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/drivers/pwm/Makefile

Sun, 17 Mar 2024 11:40:34 +0100

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/drivers/pwm/Makefile
