-* Device tree bindings for ARM PL172/PL175/PL176 MultiPort Memory Controller
-
-Required properties:
-
-- compatible: Must be "arm,primecell" and exactly one from
- "arm,pl172", "arm,pl175" or "arm,pl176".
-
-- 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, option is not supported by
- PL175 and PL176 controllers.
-
-- 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.

+
+description: |
+ The STM32 Octo Memory Manager is a low-level interface that enables an
+ efficient OCTOSPI pin assignment with a full I/O matrix (before alternate
+ function map) and multiplex of single/dual/quad/octal SPI interfaces over
+ the same bus. It Supports up to:
+ - Two single/dual/quad/octal SPI interfaces
+ - Two ports for pin assignment
