Subject: ARM: DT: apq8064: Add sdcc support via mcci driver.
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=045644ffe618f140791643aa8b78ad2587e8de0f;p=openwrt%2Fstaging%2Fblogic.git

ARM: DT: apq8064: Add sdcc support via mcci driver.

This patch adds support to SD card controller using generic pl180 mmci driver.
This patch also adds temporary fixed regulator to get it going till the actual
regulator is mainlined.
