Subject: [PATCH] ARM: dts: omap3430-sdp: add dip switch information for MMC operation
Date: Mon, 6 Jan 2014 16:37:33 -0600 [thread overview]
Message-ID: <1389047853-26375-1-git-send-email-nm@ti.com> (raw)
MMC 8 bit mode operation depends on dip switch setting which is not
obvious - The current board file has this description. However, with
removal of the board file in the future, this information will be lost
and has to be rediscovered.
