On omap4 we're missing the fdif node with it's related "ti,hwmods"
property that the SoC interconnect code needs.
Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.

+Texas Instruments Face Detect (FDIF) binding
+
+FDD can be used for face detection on Texas Instruments SoCs.
+
+Note that the fdif binding is currently only used by the SoC interconnect
+code to idle the module on init and no open source driver is available
+for fdif. Please update this documentation if that changes.
+
+
+Required properties:
+
+compatible: Shall be one of the following:
+ "ti,omap4-fdif"
+
+reg: Shall contain the device instance IO range
+
+interrupts: Shall contain the device instance interrupt
+
+
+Optional properties:
+
+reg-names: Shall contain the IO range names if multiple IO
+ ranges are used by the SoC
+
+ti,hwmods: Shall contain the TI interconnect module name if needed
+ by the SoC
+
+
+Example:
+
+ fdif: fdif@4a10a000 {
+ compatible = "ti,omap4-fdif";
+ reg = <0x4a10a000 0x200>;
+ interrupts = <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "fdif";
+ };
