MIPI DSI (Display Serial Interface) busses
==========================================
The MIPI Display Serial Interface specifies a serial bus and a protocol for
communication between a host and up to four peripherals. This document will
define the syntax used to represent a DSI bus in a device tree.
This document describes DSI bus-specific properties only or defines existing
standard properties in the context of the DSI bus.
Each DSI host provides a DSI bus. The DSI host controller's node contains a
set of properties that characterize the bus. Child nodes describe individual
peripherals on that bus.
The following assumes that only a single peripheral is connected to a DSI
host. Experience shows that this is true for the large majority of setups.
DSI host
--------
In addition to the standard properties and those defined by the parent bus of
a DSI host, the following properties apply to a node representing a DSI host.
Required properties:
- #address-cells: The number of cells required to represent an address on the
bus. DSI peripherals are addressed using a 2-bit virtual channel number, so
a maximum of 4 devices can be addressed on a single bus. Hence the value of
this property should be 1.
- #size-cells: Should be 0. There are cases where it makes sense to use a
different value here. See below.
DSI peripheral
--------------
Peripherals are represented as child nodes of the DSI host's node. Properties
described here apply to all DSI peripherals, but individual bindings may want
to define additional, device-specific properties.
Required properties:
- reg: The virtual channel number of a DSI peripheral. Must be in the range
from 0 to 3.
Some DSI peripherals respond to more than a single virtual channel. In that
case two alternative representations can be chosen:
- The reg property can take multiple entries, one for each virtual channel
that the peripheral responds to.
- If the virtual channels that a peripheral responds to are consecutive, the
#size-cells can be set to 1. The first cell of each entry in the reg
property is the number of the first virtual channel and the second cell is
the number of consecutive virtual channels.
Example
-------
dsi-host {
...
#address-cells = <1>;
#size-cells = <0>;
/* peripheral responds to virtual channel 0 */
peripheral@0 {
compatible = "...";
reg = <0>;
};
...
};
dsi-host {
...
#address-cells = <1>;
#size-cells = <0>;
/* peripheral responds to virtual channels 0 and 2 */
peripheral@0 {
compatible = "...";
reg = <0, 2>;
};
...
};
dsi-host {
...
#address-cells = <1>;
#size-cells = <1>;
/* peripheral responds to virtual channels 1, 2 and 3 */
peripheral@1 {
compatible = "...";
reg = <1 3>;
};
...
};

NVIDIA Tegra MIPI pad calibration controller
Required properties:
- compatible: "nvidia,tegra<chip>-mipi"
- reg: Physical base address and length of the controller's registers.
- clocks: Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
- clock-names: Must include the following entries:
- mipi-cal
- #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads
that need to be calibrated for a given device.
User nodes need to contain an nvidia,mipi-calibrate property that has a
phandle to refer to the calibration controller node and a bitmask of the pads
that need to be calibrated.
Example:
mipi: mipi@700e3000 {
compatible = "nvidia,tegra114-mipi";
reg = <0x700e3000 0x100>;
clocks = <&tegra_car TEGRA114_CLK_MIPI_CAL>;

* naturally enforces the correct ordering between the bail-out of the
* waiter and the gpu reset work code.
