-Device tree bindings for OMAP general purpose memory controllers (GPMC)
-
-The actual devices are instantiated from the child nodes of a GPMC node.
-
-Required properties:
-
- - compatible:		Should be set to one of the following:
-
-			ti,omap2420-gpmc (omap2420)
-			ti,omap2430-gpmc (omap2430)
-			ti,omap3430-gpmc (omap3430 & omap3630)
-			ti,omap4430-gpmc (omap4430 & omap4460 & omap543x)
-			ti,am3352-gpmc   (am335x devices)
-
- - reg:			A resource specifier for the register space
-			(see the example below)
- - ti,hwmods:		Should be set to "ti,gpmc" until the DT transition is
-			completed.
- - #address-cells:	Must be set to 2 to allow memory address translation
- - #size-cells:		Must be set to 1 to allow CS address passing
- - gpmc,num-cs:		The maximum number of chip-select lines that controller
-			can support.
- - gpmc,num-waitpins:	The maximum number of wait pins that controller can
-			support.
- - ranges:		Must be set up to reflect the memory layout with four
-			integer values for each chip-select line in use:
-
-			   <cs-number> 0 <physical address of mapping> <size>
-
-			Currently, calculated values derived from the contents
-			of the per-CS register GPMC_CONFIG7 (as set up by the
-			bootloader) are used for the physical address decoding.
-			As this will change in the future, filling correct
-			values here is a requirement.
- - interrupt-controller: The GPMC driver implements and interrupt controller for
-			the NAND events "fifoevent" and "termcount" plus the
-			rising/falling edges on the GPMC_WAIT pins.
-			The interrupt number mapping is as follows
-			0 - NAND_fifoevent
-			1 - NAND_termcount
-			2 - GPMC_WAIT0 pin edge
-			3 - GPMC_WAIT1 pin edge, and so on.
- - interrupt-cells:	Must be set to 2
- - gpio-controller:	The GPMC driver implements a GPIO controller for the
-			GPMC WAIT pins that can be used as general purpose inputs.
-			0 maps to GPMC_WAIT0 pin.
- - gpio-cells:		Must be set to 2
-
-Required properties when using NAND prefetch dma:
- - dmas			GPMC NAND prefetch dma channel
- - dma-names		Must be set to "rxtx"
-
-Timing properties for child nodes. All are optional and default to 0.
-
- - gpmc,sync-clk-ps:	Minimum clock period for synchronous mode, in picoseconds

- - gpmc,clk-activation-ns: 	GPMC clock activation time
- - gpmc,wait-monitoring-ns:	Start of wait monitoring with regard to valid
-				data
-
-Boolean timing parameters. If property is present parameter enabled and
-disabled if omitted:
- - gpmc,adv-extra-delay:	ADV signal is delayed by half GPMC clock
- - gpmc,cs-extra-delay:		CS signal is delayed by half GPMC clock
- - gpmc,cycle2cycle-diffcsen:	Add "cycle2cycle-delay" between successive
-				accesses to a different CS

-- gpmc,device-width	Total width of device(s) connected to a GPMC
-			chip-select in bytes. The GPMC supports 8-bit
-			and 16-bit devices and so this property must be
-			1 or 2.
-- gpmc,mux-add-data	Address and data multiplexing configuration.
-			Valid values are 1 for address-address-data
-			multiplexing mode and 2 for address-data
-			multiplexing mode.
-- gpmc,sync-read	Enables synchronous read. Defaults to asynchronous
-			is this is not set.
-- gpmc,sync-write	Enables synchronous writes. Defaults to asynchronous
-			is this is not set.

-			"gpmc,num-waitpins".
-- gpmc,wait-on-read	Enables wait monitoring on reads.
-- gpmc,wait-on-write	Enables wait monitoring on writes.

-Example for an AM33xx board:
-
-	gpmc: gpmc@50000000 {
-		compatible = "ti,am3352-gpmc";
