On omap4 we're missing the iss 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 Imaging Subsystem (ISS) binding
+
+ISS is used for cameras on Texas Instruments SoCs. Note that this
+binding is still missing the connections to the external devices
+modeled for the driver.
+
+Required properties:
+
+compatible: Shall be one of the following:
+ "ti,omap4-iss"
+
+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:
+
+ iss: iss@52000000 {
+ compatible = "ti,omap4-iss";
+ reg = <0x52000000 0x1000000>;
+ interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "iss";
+ };
