*	pwm: gpio: Switch to use hrtimer_setup()	Nam Cao	2025-02-07	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism.

*	pwm: Add GPIO PWM driver	Vincent Whitchurch	2024-07-10	1	-0/+241
	Add a software PWM which toggles a GPIO from a high-resolution timer. This will naturally not be as accurate or as efficient as a hardware PWM, but it is useful in some cases. I have for example used it for evaluating LED brightness handling (via leds-pwm) on a board where the LED was just hooked up to a GPIO, and for a simple verification of the timer frequency on another platform. Since high-resolution timers are used, sleeping GPIO chips are not supported and are rejected in the probe function.
