Subject: [PATCH 12/12] mmc: core: Add DT-bindings for MMC_CAP2_FULL_PWR_CYCLE
Date: Mon, 10 Jun 2013 17:03:47 +0200	[thread overview]
Message-ID: <1370876627-13439-13-git-send-email-ulf.hansson@stericsson.com> (raw)
In-Reply-To: <1370876627-13439-1-git-send-email-ulf.hansson@stericsson.com>

From: Ulf Hansson <ulf.hansson@linaro.org>

The DT-binding for MMC_CAP2_FULL_PWR_CYCLE, is used to indicate whether
it is possible to perform a full power cycle of the card.
