Merge branch 'omap/dt' into next/late
As pointed out by Stephen Rothwell, commit e52117638b79 ("ARM: dts: omap3: Add DT entries for OMAP 3 ISP") conflicts with b8845074cfbb ("ARM: dts: omap3: add minimal l4 bus layout with control module support") in non-obvious ways, causing a build failure when both patches are present. This merges the two branches that introduce the respective changes into the next/late branch to resolve the way that Stephen suggested, as confirmed by Tony.

+OMAP 3 ISP Device Tree bindings
+===============================
+
+The DT definitions can be found in include/dt-bindings/media/omap3-isp.h.
+
+Required properties
+===================
+
+compatible : must contain "ti,omap3-isp"
+
+reg : the two registers sets (physical address and length) for the
+ ISP. The first set contains the core ISP registers up to
+ the end of the SBL block. The second set contains the
+ CSI PHYs and receivers registers.
+interrupts : the ISP interrupt specifier
+iommus : phandle and IOMMU specifier for the IOMMU that serves the ISP
+syscon : the phandle and register offset to the Complex I/O or CSI-PHY
+ register
+ti,phy-type : 0 -- OMAP3ISP_PHY_TYPE_COMPLEX_IO (e.g. 3430)
+ 1 -- OMAP3ISP_PHY_TYPE_CSIPHY (e.g. 3630)
+#clock-cells : Must be 1 --- the ISP provides two external clocks,
+ cam_xclka and cam_xclkb, at indices 0 and 1,
+ respectively. Please find more information on common
+ clock bindings in ../clock/clock-bindings.txt.
+
+Port nodes (optional)
+---------------------
+
+More documentation on these bindings is available in
+video-interfaces.txt in the same directory.
+
+reg : The interface:
+ 0 - parallel (CCDC)
+ 1 - CSIPHY1 -- CSI2C / CCP2B on 3630;
+ CSI1 -- CSIb on 3430
+ 2 - CSIPHY2 -- CSI2A / CCP2B on 3630;
+ CSI2 -- CSIa on 3430
+
+Optional properties
+===================
+
+vdd-csiphy1-supply : voltage supply of the CSI-2 PHY 1
+vdd-csiphy2-supply : voltage supply of the CSI-2 PHY 2
+
+Endpoint nodes
+--------------
+
+lane-polarities : lane polarity (required on CSI-2)
+ 0 -- not inverted; 1 -- inverted
+data-lanes : an array of data lanes from 1 to 3. The length can
+ be either 1 or 2. (required on CSI-2)
+clock-lanes : the clock lane (from 1 to 3). (required on CSI-2)
+
+
+Example
+=======
+
+ isp@480bc000 {
+ compatible = "ti,omap3-isp";
+ reg = <0x480bc000 0x12fc
+ 0x480bd800 0x0600>;
+ interrupts = <24>;
+ iommus = <&mmu_isp>;
+ syscon = <&scm_conf 0x2f0>;
+ ti,phy-type = <OMAP3ISP_PHY_TYPE_CSIPHY>;
+ #clock-cells = <1>;
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
+ };
