* Nodes
|
|
|
|
- ports:
|
|
Usage: required
|
|
Definition: As described in video-interfaces.txt in same directory.
|
|
Properties:
|
|
- reg:
|
|
Usage: required
|
|
Value type: <u32>
|
|
Definition: Selects CSI2 PHY interface - PHY0, PHY1
|
|
or PHY2 (8996 only)
|
|
Endpoint node properties:
|
|
- clock-lanes:
|
|
Usage: required
|
|
Value type: <u32>
|
|
Definition: The physical clock lane index. On 8916
|
|
the value must always be <1> as the physical
|
|
clock lane is lane 1. On 8996 the value must
|
|
always be <7> as the hardware supports D-PHY
|
|
and C-PHY, indexes are in a common set and
|
|
D-PHY physical clock lane is labeled as 7.
|
|
- data-lanes:
|
|
Usage: required
|
|
Value type: <prop-encoded-array>
|
|
Definition: An array of physical data lanes indexes.
|
|
Position of an entry determines the logical
|
|
lane number, while the value of an entry
|
|
indicates physical lane index. Lane swapping
|
|
is supported. Physical lane indexes for
|
|
8916: 0, 2, 3, 4; for 8996: 0, 1, 2, 3.
