53 a device is partitioned into multiple data busses, e.g. 16-bit input port
54 divided into two separate ITU-R BT.656 8-bit busses. In such case bus-width

460 - remote-endpoint: phandle to an 'endpoint' subnode of a remote device node.
461 - slave-mode: a boolean property indicating that the link is run in slave mode.
466 - bus-type: data bus type. Possible values are:
467 1 - MIPI CSI-2 C-PHY
468 2 - MIPI CSI1

472 6 - Bt.656
473 - bus-width: number of data lines actively used, valid for the parallel busses.
474 - data-shift: on the parallel data busses, if bus-width is used to specify the
475 number of data lines, data-shift can be used to specify which data lines are
476 used, e.g. "bus-width=<8>; data-shift=<2>;" means, that lines 9:2 are used.
477 - hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
478 - vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.

482 - data-enable-active: similar to HSYNC and VSYNC, specifies the data enable
483 signal polarity.
484 - field-even-active: field signal level during the even field data transmission.
485 - pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock
487 - sync-on-green-active: active state of Sync-on-green (SoG) signal, 0/1 for
488 LOW/HIGH respectively.
489 - data-lanes: an array of physical data lane indexes. Position of an entry
491 physical lane, e.g. for 2-lane MIPI CSI-2 bus we could have
492 "data-lanes = <1 2>;", assuming the clock lane is on hardware lane 0.
496 serial busses only (e.g. MIPI CSI-2).
497 - clock-lanes: an array of physical clock lane indexes. Position of an entry
499 physical lane, e.g. for a MIPI CSI-2 bus we could have "clock-lanes = <0>;",
501 serial busses only (e.g. MIPI CSI-2). Note that for the MIPI CSI-2 bus this
503 - clock-noncontinuous: a boolean property to allow MIPI CSI-2 non-continuous
505 - link-frequencies: Allowed data bus frequencies. For MIPI CSI-2, for
507 lane value. An array of 64-bit unsigned integers.
508 - lane-polarities: an array of polarities of the lanes starting from the clock
509 lane and followed by the data lanes in the same order as in data-lanes.
511 should be the combined length of data-lanes and clock-lanes properties.
512 If the lane-polarities property is omitted, the value must be interpreted
