Subject: [PATCH 05/11] mmc: host: omap_hsmmc: set clk rate to the max frequency
Date: Thu, 30 Jul 2015 13:16:28 +0530	[thread overview]
Message-ID: <1438242394-25599-6-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1438242394-25599-1-git-send-email-kishon@ti.com>

Set the clock rate of the functional clock to the max frequency
that is passed to the driver either using pdata or dt.

Also remove unnecessary setting of host->fclk to NULL.
