-Subject: [PATCH] pwm: Send a uevent on the pwmchip device upon channel
- sysfs (un)export
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 552c02e3e7cfe2744b59de285aaea70021ae95c9 upstream.
-
-This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
-everytime a pwmX channel has been exported/unexported via sysfs. This
-allows udev to implement rules on such events, like:
-
-SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
-        chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
-        chown -R root:gpio
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip* && chmod -R 770
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
-'"
-
-This is a replacement patch for commit 7e5d1fd75c3d ("pwm: Set class for
-exported channels in sysfs"), see [1].
-
-basic testing:
-$ udevadm monitor --environment &
-$ echo 0 > /sys/class/pwm/pwmchip0/export
-KERNEL[197.321736] change   /devices/.../pwm/pwmchip0 (pwm)
-ACTION=change
-DEVPATH=/devices/.../pwm/pwmchip0
-EXPORT=pwm0
-SEQNUM=2045
-SUBSYSTEM=pwm
