From mboxrd@z Thu Jan 1 00:00:00 1970 From: boris.brezillon@free-electrons.com (Boris Brezillon) Date: Mon, 21 Sep 2015 11:33:25 +0200 Subject: [PATCH v3 08/12] pwm: add information about polarity, duty cycle and period to debugfs In-Reply-To: <1442828009-6241-1-git-send-email-boris.brezillon@free-electrons.com> References: <1442828009-6241-1-git-send-email-boris.brezillon@free-electrons.com> Message-ID: <1442828009-6241-9-git-send-email-boris.brezillon@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Heiko St?bner 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.
