From 23e3523f5d3a980edf7f189743cf4bb9490400a9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Heiko=20St=C3=BCbner?= Date: Thu, 14 Apr 2016 21:17:44 +0200 Subject: [PATCH] pwm: Add information about polarity, duty cycle and period to debugfs The PWM states make it possible to also output the polarity, duty cycle and period information in the debugfs summary output. This simplifies gathering information about PWMs without needing to walk through the sysfs attributes of every PWM.
