zephyr,panel-timing
Vendor: Zephyr-specific binding
Description
Common timing settings for display panels. These timings can be added to
a panel under display-timings node. For example:
&lcdif {
display-timings {
compatible = "zephyr,panel-timing";
hsync-len = <8>;
hfront-porch = <32>;
hback-porch = <32>;
vsync-len = <2>;
vfront-porch = <16>;
vback-porch = <14>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <0>;
clock-frequency = <62346240>;
};
};

|
Pixel clock for display controller in Hz. Must be at least as large as:
(height + vsync-len + vfront-porch + vback-porch) *
(width + hsync-len + hfront-porch + hback-porch) *
desired frame rate

Horizontal synchronization pulse duration of panel driven by this
controller, in pixels
This property is required. |
|
|
Vertical synchronization pulse duration of panel driven by this
controller, in lines
This property is required. |
|
|
Horizontal back porch duration of panel driven by this controller,
in pixels
This property is required. |
|
|
Vertical back porch duration of panel driven by this controller, in lines
This property is required. |
|
|
Horizontal front porch duration of panel driven by this controller,
in pixels
This property is required. |
|
|
Vertical front porch duration of panel driven by this controller, in lines
This property is required. |
|
|
Polarity of horizontal sync pulse
0 selects active low
1 selects active high
This property is required. Legal values: |
|
|
Polarity of vertical sync pulse
0 selects active low
1 selects active high
This property is required. Legal values: |
|
|
Polarity of data enable, sent with each horizontal interval.
0 selects active low
1 selects active high.
This property is required. Legal values: |
|
|
Polarity of pixel clock. Selects which edge to drive data to display on.
0 drives pixel data on falling edge, and samples on rising edge.
1 drives pixel data on rising edge, and samples data on falling edge
This property is required. Legal values: |
|
|
Drive sync on rising or sample sync on falling edge. If not specified
then the controller uses the setup specified by pixelclk-active.
Use 0 to drive sync on falling edge
and sample sync on rising edge of pixel clock.
Use 1 to drive sync on rising edge
and sample sync on falling edge of pixel clock.
