Subject: [PATCH v2 08/10] pwm: add information about polarity, duty cycle and period to debugfs
Date: Mon, 20 Jul 2015 17:32:05 +0200 [thread overview]
Message-ID: <1437406327-6207-9-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1437406327-6207-1-git-send-email-boris.brezillon@free-electrons.com>
From: Heiko Stübner <heiko@sntech.de>
The pwm-states make it possible to also output the polarity, duty cycle
and period information in the debugfs pwm summary-outout.
This makes it easier to gather overview information about pwms without
needing to walk through the sysfs attributes of every pwm.
