1OMAP 3 ISP Device Tree bindings
2===============================

4The DT definitions can be found in include/dt-bindings/media/omap3-isp.h.

6Required properties
7===================
8
9compatible	: must contain "ti,omap3-isp"
10
11reg		: the two registers sets (physical address and length) for the
12		  ISP. The first set contains the core ISP registers up to
13		  the end of the SBL block. The second set contains the
14		  CSI PHYs and receivers registers.
15interrupts	: the ISP interrupt specifier
16iommus		: phandle and IOMMU specifier for the IOMMU that serves the ISP
17syscon		: the phandle and register offset to the Complex I/O or CSI-PHY
18		  register
19ti,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. Please find more information on common
24		  clock bindings in ../clock/clock-bindings.txt.

26Port nodes (optional)
27---------------------

29More documentation on these bindings is available in
30video-interfaces.txt in the same directory.
31
32reg		: The interface:
33		  0 - parallel (CCDC)
34		  1 - CSIPHY1 -- CSI2C / CCP2B on 3630;
35		      CSI1 -- CSIb on 3430
36		  2 - CSIPHY2 -- CSI2A / CCP2B on 3630;
37		      CSI2 -- CSIa on 3430
38
39Optional properties
40===================
41
42vdd-csiphy1-supply : voltage supply of the CSI-2 PHY 1
43vdd-csiphy2-supply : voltage supply of the CSI-2 PHY 2
44
45Endpoint nodes
46--------------
47
48lane-polarities	: lane polarity (required on CSI-2)
49		  0 -- not inverted; 1 -- inverted
50data-lanes	: an array of data lanes from 1 to 3. The length can
51		  be either 1 or 2. (required on CSI-2)
52clock-lanes	: the clock lane (from 1 to 3). (required on CSI-2)
