ARM: mmc: bcm281xx SDHCI driver (dt mods) Add SDHCI bindings for the Broadcom 281xx SoCs. Changes from V2: - Documentation cleanups Changes from V1: - split original patch into 2, one for driver and this one for dt Signed-off-by: Christian Daudt <csd@broadcom.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

Broadcom BCM281xx SDHCI
This file documents differences between the core properties in mmc.txt
and the properties present in the bcm281xx SDHCI
Required properties:
ARM: DT: binding fixup to align with vendor-prefixes.txt (DT) [ this is a follow-up to this discussion: http://archive.arm.linux.org.uk/lurker/message/20130730.230827.a1ceb12a.en.html ] This patchset renames all uses of "bcm," name bindings to "brcm," as they were done prior to knowing that brcm had already been standardized as Broadcom vendor prefix (in Documentation/devicetree/bindings/vendor-prefixes.txt). This will not cause any churn on devices because none of these bindings have made it into production yet. Also rename the the following dt binding docs that had "bcm," in their name for consistency: - bcm,kona-sdhci.txt -> kona-sdhci.txt - bcm,kona-timer.txt -> kona-timer.txt Signed-off-by: Christian Daudt <csd@broadcom.com> Acked-by: Stephen Warren <swarren@nvidia.com>

- compatible : Should be "brcm,kona-sdhci"
- DEPRECATED: compatible : Should be "bcm,kona-sdhci"
Documentation: dt: kona-sdhci: Add clocks property The Kona SDHCI block requires a clock that must be specified in the device tree. Update the documentation to reflect this requirement.

- clocks: phandle + clock specifier pair of the external clock
