Multiple of slice width should be equal to panel-width. Maximum 2 slices per DSC encoder can be used so if 2 DSC encoders are used then minimum slice width is equal to panel-width/4. - qcom,mdss-dsc-slice-per-pkt: An integer value indicates the slice per dsi packet. - qcom,mdss-dsc-bit-per-component: An integer value indicates the bits per component before compression. - qcom,mdss-dsc-bit-per-pixel: An integer value indicates the bits per pixel after compression. - qcom,mdss-dsc-block-prediction-enable: A boolean value to enable/disable the block prediction at decoder. - qcom,mdss-dsc-config-by-manufacture-cmd: A boolean to indicates panel use manufacture command to setup pps instead of standard dcs type 0x0A. - qcom,display-topology: Array of u32 values which specifies the list of topologies available for the display. A display topology is defined by a set of 3 values in the order: - number of mixers - number of compression encoders - number of interfaces Therefore, the array should always contain a tuple of 3 elements. - qcom,default-topology-index: An u32 value which indexes the topology set specified by the node "qcom,display-topology" to identify the default topology for the display. The first set is indexed by the value 0. - qcom,mdss-dsi-ext-bridge: Array of u32 values which specifies the external bridge chip reg number, it should match the port config. - qcom,mdss-dsi-dma-schedule-line: An integer value indicates the line number after vertical active region, at which command DMA needs to be triggered. - qcom,dsi-dyn-clk-enable: Boolean to indicate dsi dynamic clock switch feature is supported. - qcom,dsi-dyn-clk-list: An u32 array which lists all the supported dsi bit clock frequencies in Hz for the given panel. - qcom,dsi-dyn-clk-skip-timing-update: Boolean to specify whether to skip phy timing parameter update during dynamic clock switch. Required properties for sub-nodes: None Optional properties: - qcom,dba-panel: Indicates whether the current panel is used as a display bridge to a non-DSI interface. - qcom,bridge-name: A string to indicate the name of the bridge chip connected to DSI. qcom,bridge-name is required if qcom,dba-panel is defined for the panel. - qcom,adjust-timer-wakeup-ms: An integer value to indicate the timer delay(in ms) to accommodate s/w delay while configuring the event timer wakeup logic. - qcom,mdss-dsi-display-timings: Parent node that lists the different resolutions that the panel supports. Each child represents timings settings for a specific resolution. - qcom,mdss-dsi-post-init-delay: Specifies required number of frames to wait so that panel can be functional to show proper display. Additional properties added to the second level nodes that represent timings properties: - qcom,mdss-dsi-timing-default: Property that specifies the current child as the default timing configuration that will be used. - qcom,mdss-dsi-timing-switch-command: List of commands that need to be sent to panel when the resolution/timing switch happens dynamically. Refer to "qcom,mdss-dsi-on-command" section for adding commands. - qcom,mdss-dsi-timing-switch-command-state: String that specifies the ctrl state for sending resolution switch commands. "dsi_lp_mode" = DSI low power mode (default) "dsi_hs_mode" = DSI high speed mode Note, if a given optional qcom,* binding is not present, then the driver will configure the default values specified.
