The first set contains the core ISP registers up to13 the end of the SBL block. The second set contains the14 CSI PHYs and receivers registers.15interrupts : the ISP interrupt specifier16iommus : phandle and IOMMU specifier for the IOMMU that serves the ISP17syscon : the phandle and register offset to the Complex I/O or CSI-PHY18 register19ti,phy-type : 0 -- OMAP3ISP_PHY_TYPE_COMPLEX_IO (e.g. 3430)20 1 -- OMAP3ISP_PHY_TYPE_CSIPHY (e.g. 3630)21#clock-cells : Must be 1 --- the ISP provides two external clocks,22 cam_xclka and cam_xclkb, at indices 0 and 1,23 respectively.
