[PATCH v2 1/1] ARM: dove: DT support for sdhci-dove

[Sebastian Hesselbarth <sebastian.hesselbarth@googlemail.com>]

This patch adds device tree support and binding documentiation for
sdhci-dove.

v2: extended documentation and removed second interrupt as it is marked 
    'reserved' in dove datasheet.

+Required properties:
+- compatible: Should be "marvell,dove-sdhci".
+- reg: Physical base address of the sdhci controller.
+- interrupts: interrupt nr of the sdhci controller.

+Example:
+
+sdio0: sdio@92000 {
+	compatible = "marvell,dove-sdhci";
+	reg = <0x92000 0x100>;
+	interrupts = <35>;
