ARM: 7378/1: mmci: add support for the Nomadik MMCI variant
The Nomadik variant is somewhere inbetween the U300 and the Ux500 variant, its actually expose the same primecell ID as the U300 but had different characteristics so it needs a small revision bump and hard-coding from the board/device tree. After this it works just fine. Acked-by: Ulf Hansson <ulf.hansson@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
