16 host. Experience shows that this is true for the large majority of setups.
18 DSI host
22 a DSI host, the following properties apply to a node representing a DSI host.
25 - #address-cells: The number of cells required to represent an address on the
26 bus. DSI peripherals are addressed using a 2-bit virtual channel number, so
29 - #size-cells: Should be 0. There are cases where it makes sense to use a
33 - clock-master: boolean. Should be enabled if the host is being used in
34 conjunction with another DSI host to drive the same peripheral. Hardware

47 as child nodes of the DSI host's node. Properties described here apply to all
49 device-specific properties.
52 - reg: The virtual channel number of a DSI peripheral. Must be in the range
57 - The reg property can take multiple entries, one for each virtual channel
59 - If the virtual channels that a peripheral responds to are consecutive, the
60 #size-cells can be set to 1. The first cell of each entry in the reg
