-display-timing bindings
-=======================
-
-display-timings node
---------------------
-
-required properties:
- - none
-
-optional properties:
- - native-mode: The native mode for the display, in case multiple modes are
- provided. When omitted, assume the first node is the native.
-
-timing subnode
---------------
-
-required properties:
- - hactive, vactive: display resolution
- - hfront-porch, hback-porch, hsync-len: horizontal display timing parameters
- in pixels
- vfront-porch, vback-porch, vsync-len: vertical display timing parameters in
- lines
- - clock-frequency: display clock in Hz
-
-optional properties:
- - hsync-active: hsync pulse is active low/high/ignored
- - vsync-active: vsync pulse is active low/high/ignored
- - de-active: data-enable pulse is active low/high/ignored
- - pixelclk-active: with
- - active high = drive pixel data on rising edge/
- sample data on falling edge
- - active low = drive pixel data on falling edge/
- sample data on rising edge
- - ignored = ignored
- - syncclk-active: with
- - active high = drive sync on rising edge/
- sample sync on falling edge of pixel
- clock
- - active low = drive sync on falling edge/
- sample sync on rising edge of pixel
- clock
- - omitted = same configuration as pixelclk-active
- - interlaced (bool): boolean to enable interlaced mode
- - doublescan (bool): boolean to enable doublescan mode
- - doubleclk (bool): boolean to enable doubleclock mode
-
-All the optional properties that are not bool follow the following logic:
- <1>: high active
- <0>: low active
- omitted: not used on hardware
-
-There are different ways of describing the capabilities of a display. The
-devicetree representation corresponds to the one commonly found in datasheets
-for displays. If a display supports multiple signal timings, the native-mode
-can be specified.
-
-The parameters are defined as:
-
- +----------+-------------------------------------+----------+-------+
- | | ^ | | |
- | | |vback_porch | | |
- | | v | | |
- +----------#######################################----------+-------+
- | # ^ # | |
- | # | # | |
- | hback # | # hfront | hsync |
- | porch # | hactive # porch | len |
- |<-------->#<-------+--------------------------->#<-------->|<----->|

- | | ^ | | |
- | | |vsync_len | | |
- | | v | | |
- +----------+-------------------------------------+----------+-------+
-
-Note: In addition to being used as subnode(s) of display-timings, the timing
- subnode may also be used on its own. This is appropriate if only one mode
- need be conveyed. In this case, the node should be named 'panel-timing'.
-
-
-Example:
-
- display-timings {
- native-mode = <&timing0>;
- timing0: 1080p24 {
- /* 1920x1080p24 */
- clock-frequency = <52000000>;
- hactive = <1920>;
- vactive = <1080>;
- hfront-porch = <25>;
- hback-porch = <25>;
- hsync-len = <25>;
- vback-porch = <2>;
- vfront-porch = <2>;
- vsync-len = <2>;
- hsync-active = <1>;
- };
- };
-
-Every required property also supports the use of ranges, so the commonly used
-datasheet description with minimum, typical and maximum values can be used.
-
-Example:
-
- timing1: timing {
- /* 1920x1080p24 */
- clock-frequency = <148500000>;
- hactive = <1920>;
- vactive = <1080>;
- hsync-len = <0 44 60>;
- hfront-porch = <80 88 95>;
- hback-porch = <100 148 160>;
- vfront-porch = <0 4 6>;
- vback-porch = <0 36 50>;
- vsync-len = <0 5 6>;
- };
