-[[Optional config sub-nodes]] These subnodes provide different
configurations for a given same panel.
- Default configuration can be chosen by
specifying phandle of the
- selected subnode in the
qcom,config-select.
-Required properties for sub-nodes: None
-Optional properites:
-- qcom,lm-split: An array of two values indicating MDP
should use two layer
- mixers to reduce power.
- Ex: Normally 1080x1920 display uses
single DSI and thus one layer
- mixer. But if we use two layer
mixers then mux the output of
- those two mixers into single stream
and route it to single DSI
- then we can lower the clock
requirements of MDP. To use this
- configuration we need two fill this
array with <540 540>.
- Both values doesn't have to be same,
but recommended, however sum of
- both values has to be equal to the
panel-width.
- By default two mixer streams are merged
using 2D mux, however if
- 2 DSC encoders are used then merge is
performed within compression
- engine.
-- qcom,split-mode: String property indicating which split
mode MDP should use. Valid
- entries are "pingpong-split" and
"dualctl-split".
- This property is mutually exclusive
with qcom,lm-split.
-- qcom,mdss-dsc-version: An 8 bit value indicates the DSC
version supported by panel. Bits[0.3]
- provides information about minor
version while Bits[4.7] provides
- major version information. It supports
only DSC rev 1(Major).1(Minor)
- right now.
-- qcom,mdss-dsc-scr-version: Each DSC version can have multiple SCR.
This 8 bit value indicates
- current SCR revision information
supported by panel.
-- qcom,mdss-dsc-encoders: An integer value indicating how many
DSC encoders should be used
- to drive data stream to DSI.
- Default value is 1 and max value is 2.
- 2 encoder should be used only if
qcom,mdss-lm-split or
- qcom,split-mode with pingpong-split is
used.
-- qcom,mdss-dsc-slice-height: An integer value indicates the dsc
slice height.
-- qcom,mdss-dsc-slice-width: An integer value indicates the dsc
slice width.
- 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,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.
