-ML-AHB interconnect bindings
-
-These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
-a Cortex-M subsystem with dedicated memories.
-The MCU SRAM and RETRAM memory parts can be accessed through different addresses
-(see "RAM aliases" in [1]) using different buses (see [2]) : balancing the
-Cortex-M firmware accesses among those ports allows to tune the system
-performance.

-
-Required properties:
-- compatible: should be "simple-bus"
-- dma-ranges: describes memory addresses translation between the local CPU and
-	   the remote Cortex-M processor. Each memory region, is declared with
-	   3 parameters:
-		 - param 1: device base address (Cortex-M processor address)
-		 - param 2: physical base address (local CPU address)
-		 - param 3: size of the memory region.
-
-The Cortex-M remote processor accessed via the mlahb interconnect is described
-by a child node.
-
-Example:
-mlahb {
-	compatible = "simple-bus";
-	#address-cells = <1>;
-	#size-cells = <1>;
-	dma-ranges = <0x00000000 0x38000000 0x10000>,
-		     <0x10000000 0x10000000 0x60000>,
-		     <0x30000000 0x30000000 0x60000>;

-	m4_rproc: m4@10000000 {

-Properties:
-   - compatible : should contain two values. First value must be :
-                 - " st,stm32mp157-syscfg " - for stm32mp157 based SoCs,
-                 second value must be always "syscon".
-   - reg : offset and length of the register set.
-   - clocks: phandle to the syscfg clock
-
- Example:
-         syscfg: syscon@50020000 {
-                 compatible = "st,stm32mp157-syscfg", "syscon";
-                 reg = <0x50020000 0x400>;
-                 clocks = <&rcc SYSCFG>;
-         };
