Subject: [PATCH v2 4/5] gpio: of: Add documentation of new sleep standard GPIO specifiers
Date: Tue, 23 May 2017 15:47:31 +0100 [thread overview]
Message-ID: <1495550852-3672-4-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1495550852-3672-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>
Add documentation of new GPIO specifiers indicating if the state of an
output pin should be maintained during sleep/low-power mode.
