The IT6162 is an I2C-controlled bridge that supports the following configurations: - Single MIPI DSI input: up to 4K @ 30Hz - Dual MIPI DSI input (combined): up to 4K @ 60Hz The chip also supports up to 8-channel audio output via 4 I2S data channels. Signed-off-by: Hermes Wu Reviewed-by: Krzysztof Kozlowski --- Changes in v4: - Drop ite,support-hdcp - Drop endpoint properties already in video-interfaces.yaml - Fix data-lanes in example with <0 1 2 3> - Add blanking line in example before endpoint subnode starts - Add reset-gpio and power controls to required Changes in v3: - Fix lane-polarities: remove $ref redefinition, allow via video-interfac= es.yaml - Improve ite,support-hdcp description to clarify FW-based HDCP behavior - Remove descriptions repeating schema constraints - Remove stray comment in ports required section - Fix data-lanes spacing in example: <1 2 3 4> - Add missing newline at end of file - Add missing change log that Reviewed-by tag was drop in V2. Changes in V2: - Drop Reviewed-by tag due to DT bindings changed. - Add property "ite,spport-hdcp" to enable HDCP - Add property "lane-polarities" and "clock-noncontinuous" for DSI setting --- .../bindings/display/bridge/ite,it6162.yaml | 169 +++++++++++++++++= ++++ 1 file changed, 169 insertions(+) diff --git a/Documentation/devicetree/bindings/display/bridge/ite,it6162.ya= ml b/Documentation/devicetree/bindings/display/bridge/ite,it6162.yaml new file mode 100644 index 0000000000000000000000000000000000000000..d1d8a92825d253ecfa67cb1e793= d372e4011b4d4 --- /dev/null +++ b/Documentation/devicetree/bindings/display/bridge/ite,it6162.yaml @@ -0,0 +1,169 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/bridge/ite,it6162.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ITE IT6162 MIPI DSI to HDMI 2.0 Bridge + +maintainers: + - Hermes Wu + +description: | + The ITE IT6162 is a high-performance, low-power HDMI bridge that converts + 2 MIPI DSI signals to 1 HDMI 2.0 output.
