* Toshiba TC358743 HDMI-RX to MIPI CSI2-TX Bridge
|
||
|
|
|
||
|
|
The Toshiba TC358743 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts
|
||
|
|
a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C.
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
|
||
|
|
- compatible: value should be "toshiba,tc358743"
|
||
|
|
- clocks, clock-names: should contain a phandle link to the reference clock
|
||
|
|
source, the clock input is named "refclk".
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
|
||
|
|
- reset-gpios: gpio phandle GPIO connected to the reset pin
|
||
|
|
- interrupts, interrupt-parent: GPIO connected to the interrupt pin
|
||
|
|
- data-lanes: should be <1 2 3 4> for four-lane operation,
|
||
|
|
or <1 2> for two-lane operation
|
||
|
|
- clock-lanes: should be <0>
|
||
|
|
- clock-noncontinuous: Presence of this boolean property decides whether the
|
||
|
|
MIPI CSI-2 clock is continuous or non-continuous.
|
||
|
|
- link-frequencies: List of allowed link frequencies in Hz. Each frequency is
|
||
|
|
expressed as a 64-bit big-endian integer. The frequency
|
||
|
|
is half of the bps per lane due to DDR transmission.
|
||
|
|
|
||
|
|
For further information on the MIPI CSI-2 endpoint node properties, see
|
||
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt.
