Subject: [PATCH v3 12/13] mmc: add DT bindings for more MMC capability flags
Date: Wed, 06 Feb 2013 19:46:59 +0000	[thread overview]
Message-ID: <1360180020-18555-13-git-send-email-g.liakhovetski@gmx.de> (raw)
In-Reply-To: <1360180020-18555-1-git-send-email-g.liakhovetski@gmx.de>

Many MMC capability flags are platform-dependent and are traditionally set
in platform data. With DT often each such capability requires a special
binding. Add bindings for MMC_CAP_SD_HIGHSPEED, MMC_CAP_MMC_HIGHSPEED,
MMC_CAP_POWER_OFF_CARD and MMC_CAP_SDIO_IRQ capabilities. Also add code to
DT parser to look up "keep-power-in-suspend" and "enable-sdio-wakeup"
bindings and set MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ respectively,
if found.
