* Marvell sdhci-pxa v2/v3 controller

This file documents differences between the core properties in mmc.txt
and the properties used by the sdhci-pxav2 and sdhci-pxav3 drivers.

Required properties:
- compatible: Should be "mrvl,pxav2-mmc" or "mrvl,pxav3-mmc".

Optional properties:
- mrvl,clk-delay-cycles: Specify a number of cycles to delay for tuning.

Example:

sdhci@d4280800 {
	compatible = "mrvl,pxav3-mmc";
	reg = <0xd4280800 0x800>;
	bus-width = <8>;
	interrupts = <27>;
	non-removable;
	mrvl,clk-delay-cycles = <31>;
};
