+* Device tree bindings for ARM PL172 MultiPort Memory Controller
+
+Required properties:
+
+- compatible:		"arm,pl172", "arm,primecell"
+
+- reg:			Must contains offset/length value for controller.
+
+- #address-cells:	Must be 2. The partition number has to be encoded in the
+			first address cell and it may accept values 0..N-1
+			(N - total number of partitions). The second cell is the
+			offset into the partition.
+
+- #size-cells:		Must be set to 1.
+
+- ranges:		Must contain one or more chip select memory regions.
+
+- clocks:		Must contain references to controller clocks.
+
+- clock-names:		Must contain "mpmcclk" and "apb_pclk".
+
+- clock-ranges:		Empty property indicating that child nodes can inherit
+			named clocks. Required only if clock tree data present
+			in device tree.
+			See clock-bindings.txt
+
+Child chip-select (cs) nodes contain the memory devices nodes connected to
+such as NOR (e.g. cfi-flash) and NAND.
+
+Required child cs node properties:
+
+- #address-cells:	Must be 2.
+
+- #size-cells:		Must be 1.
+
+- ranges:		Empty property indicating that child nodes can inherit
+			memory layout.
+
+- clock-ranges:		Empty property indicating that child nodes can inherit
+			named clocks. Required only if clock tree data present
+			in device tree.
+
+- mpmc,cs:		Chip select number. Indicates to the pl0172 driver
+			which chipselect is used for accessing the memory.
+
+- mpmc,memory-width:	Width of the chip select memory. Must be equal to
+			either 8, 16 or 32.
+
+Optional child cs node config properties:
+
+- mpmc,async-page-mode:	Enable asynchronous page mode.
+
+- mpmc,cs-active-high:	Set chip select polarity to active high.
+
+- mpmc,byte-lane-low:	Set byte lane state to low.
+
+- mpmc,extended-wait:	Enable extended wait.
+
+- mpmc,buffer-enable:	Enable write buffer.
+
+- mpmc,write-protect:	Enable write protect.
+
+Optional child cs node timing properties:
+
+- mpmc,write-enable-delay:	Delay from chip select assertion to write
+				enable (WE signal) in nano seconds.
+
+- mpmc,output-enable-delay:	Delay from chip select assertion to output
+				enable (OE signal) in nano seconds.
+
+- mpmc,write-access-delay:	Delay from chip select assertion to write
+				access in nano seconds.
+
+- mpmc,read-access-delay:	Delay from chip select assertion to read
+				access in nano seconds.
+
+- mpmc,page-mode-read-delay:	Delay for asynchronous page mode sequential
+				accesses in nano seconds.
+
+- mpmc,turn-round-delay:	Delay between access to memory banks in nano
+				seconds.
+
+If any of the above timing parameters are absent, current parameter value will
+be taken from the corresponding HW reg.
+
+Example for pl172 with nor flash on chip select 0 shown below.

 Binding for Synopsys IntelliDDR Multi Protocol Memory Controller
 
+This controller has an optional ECC support in half-bus width (16-bit)
+configuration. The ECC controller corrects one bit error and detects
+two bit errors.

 Required properties:
  - compatible: Should be 'xlnx,zynq-ddrc-a05'
  - reg: Base address and size of the controllers memory area
