+Broadcom SPI controller
+
+The Broadcom SPI controller is a SPI master found on various SOCs, including
+BRCMSTB (BCM7XXX), Cygnus, NSP and NS2. The Broadcom Master SPI hw IP consits
+of :
+ MSPI : SPI master controller can read and write to a SPI slave device
+ BSPI : Broadcom SPI in combination with the MSPI hw IP provides acceleration
+	for flash reads and be configured to do single, double, quad lane
+	io with 3-byte and 4-byte addressing support.
+
+ Supported Broadcom SoCs have one instance of MSPI+BSPI controller IP.
+ MSPI master can be used wihout BSPI. BRCMSTB SoCs have an additional instance
+ of a MSPI master without the BSPI to use with non flash slave devices that
+ use SPI protocol.
+
+Required properties:
+
+- #address-cells:
+    Must be <1>, as required by generic SPI binding.
+
+- #size-cells:
+    Must be <0>, also as required by generic SPI binding.
+
+- compatible:
+    Must be one of :
+    "brcm,spi-bcm-qspi", "brcm,spi-brcmstb-qspi" : MSPI+BSPI on BRCMSTB SoCs
+    "brcm,spi-bcm-qspi", "brcm,spi-brcmstb-mspi" : Second Instance of MSPI
+						   BRCMSTB  SoCs

+    "brcm,spi-bcm-qspi", "brcm,spi-ns2-qspi"     : NS2 SoCs
+
+- reg:
+    Define the bases and ranges of the associated I/O address spaces.
+    The required range is MSPI controller registers.
+
+- reg-names:
+    First name does not matter, but must be reserved for the MSPI controller
+    register range as mentioned in 'reg' above, and will typically contain
+    - "bspi_regs": BSPI register range, not required with compatible
+		   "spi-brcmstb-mspi"
+    - "mspi_regs": MSPI register range is required for compatible strings
+    - "intr_regs", "intr_status_reg" : Interrupt and status register for
+      NSP, NS2, Cygnus SoC
+
+- interrupts
+    The interrupts used by the MSPI and/or BSPI controller.
+
+- interrupt-names:
+    Names of interrupts associated with MSPI
+    - "mspi_halted" :
+    - "mspi_done": Indicates that the requested SPI operation is complete.
+    - "spi_lr_fullness_reached" : Linear read BSPI pipe full
+    - "spi_lr_session_aborted"  : Linear read BSPI pipe aborted
+    - "spi_lr_impatient" : Linear read BSPI requested when pipe empty
+    - "spi_lr_session_done" : Linear read BSPI session done
+
+- clocks:
+    A phandle to the reference clock for this block.
+
+Optional properties:
+
+
+- native-endian
+    Defined when using BE SoC and device uses BE register read/write
+
+Recommended optional m25p80 properties:
