+Marvell 8787/8897/8997 (sd8787/sd8897/sd8997/pcie8997) SDIO/PCIE devices
+------
+
+This node provides properties for controlling the Marvell SDIO/PCIE wireless device.
+The node is expected to be specified as a child node to the SDIO/PCIE controller that
+connects the device to the system.
+
+Required properties:
+
+  - compatible : should be one of the following:
+	* "marvell,sd8787"
+	* "marvell,sd8897"
+	* "marvell,sd8997"
+	* "pci11ab,2b42"
+	* "pci1b4b,2b42"
+
+Optional properties:
+
+  - marvell,caldata* : A series of properties with marvell,caldata prefix,
+		      represent calibration data downloaded to the device during
+		      initialization. This is an array of unsigned 8-bit values.
+		      the properties should follow below property name and
+		      corresponding array length:
+	"marvell,caldata-txpwrlimit-2g" (length = 566).
+	"marvell,caldata-txpwrlimit-5g-sub0" (length = 502).
+	"marvell,caldata-txpwrlimit-5g-sub1" (length = 688).
+	"marvell,caldata-txpwrlimit-5g-sub2" (length = 750).
+	"marvell,caldata-txpwrlimit-5g-sub3" (length = 502).
+  - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured
+		      to firmware. Firmware will wakeup the host using this pin
+		      during suspend/resume.
+  - interrupts : interrupt pin number to the cpu. driver will request an irq based on
+		 this interrupt number. during system suspend, the irq will be enabled
+		 so that the wifi chip can wakeup host platform under certain condition.
+		 during system resume, the irq will be disabled to make sure
+		 unnecessary interrupt is not received.
+  - vmmc-supply: a phandle of a regulator, supplying VCC to the card
+  - mmc-pwrseq:  phandle to the MMC power sequence node. See "mmc-pwrseq-*"
+		 for documentation of MMC power sequence bindings.
+
+Example:
+
+Tx power limit calibration data is configured in below example.
+The calibration data is an array of unsigned values, the length
+can vary between hw versions.
+IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured
+so that firmware can wakeup host using this device side pin.
