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>;
			};
		};
