    1 OMAP 3 ISP Device Tree bindings
    2 ===============================
    3 
    4 The DT definitions can be found in include/dt-bindings/media/omap3-isp.h.
    5 
    6 Required properties
    7 ===================
    8 
    9 compatible      : must contain "ti,omap3-isp"
   10 
   11 reg             : 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.
   15 interrupts      : the ISP interrupt specifier
   16 iommus          : phandle and IOMMU specifier for the IOMMU that serves the ISP
   17 syscon          : the phandle and register offset to the Complex I/O or CSI-PHY
   18                   register
   19 ti,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.
   25 
   26 Port nodes (optional)
   27 ---------------------
   28 
   29 More documentation on these bindings is available in
   30 video-interfaces.txt in the same directory.
   31 
   32 reg             : 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 
   39 Optional properties
   40 ===================
   41 
   42 vdd-csiphy1-supply : voltage supply of the CSI-2 PHY 1
   43 vdd-csiphy2-supply : voltage supply of the CSI-2 PHY 2
   44 
   45 Endpoint nodes
   46 --------------
   47 
   48 lane-polarities : lane polarity (required on CSI-2)
   49                   0 -- not inverted; 1 -- inverted
   50 data-lanes      : an array of data lanes from 1 to 3. The length can
   51                   be either 1 or 2. (required on CSI-2)
   52 clock-lanes     : the clock lane (from 1 to 3). (required on CSI-2)
