ABI: sysfs-class-pwm: use wildcards on What definitions

2021-09-21T16:31:16Z

An "N" upper letter is not a wildcard, nor can easily be identified by script, specially since the USB sysfs define things like. bNumInterfaces. Use, instead, , in order to let script/get_abi.pl to convert it into a Regex.

pwm: sysfs: Add PWM capture support

2016-06-10T14:01:40Z

Allow a user to read PWM capture results from sysfs. To start a capture and read the result, simply read the file: $ cat $PWMCHIP/capture The output format is " ". Signed-off-by: Lee Jones Signed-off-by: Thierry Reding

pwm: Add sysfs interface

2013-06-21T09:32:51Z

Add a simple sysfs interface to the generic PWM framework. /sys/class/pwm/ `-- pwmchipN/ for each PWM chip |-- export (w/o) ask the kernel to export a PWM channel |-- npwm (r/o) number of PWM channels in this PWM chip |-- pwmX/ for each exported PWM channel | |-- duty_cycle (r/w) duty cycle (in nanoseconds) | |-- enable (r/w) enable/disable PWM | |-- period (r/w) period (in nanoseconds) | `-- polarity (r/w) polarity of PWM (normal/inversed) `-- unexport (w/o) return a PWM channel to the kernel Based on work by Lars Poeschel.
