This driver is for the i.MX8MQ EVK Board.
|
||||
|
||||
Default behaviour
|
||||
~~~~~~~~~~~~~~~~~
|
||||
When no configuration is provided to the driver, it will enable the HDMI
|
||||
connector and use the best resolution as provided by EDID information from
|
||||
the HDMI display.
|
||||
|
||||
Configuration
|
||||
~~~~~~~~~~~~~
|
||||
The HDMI connector can be configured explicitly in terms of resolution and
|
||||
whether it should be enabled or not. This looks like the following:
|
||||
|
||||
! <config>
|
||||
! <connector name="HDMI-A-1" width="1920" height="1080" hz="60" enabled="true"/>
|
||||
! </config>
|
||||
|
||||
When the configuration changes during run-time, the driver will adapt to it.
|
||||
|
||||
To present all available connectors and their possible resolutions to the user
|
||||
the driver is able to export a corresponding report ROM. This has to be
|
||||
configured too, like in the following:
|
||||
|
||||
! <config>
|
||||
! <report connectors="yes"/>
|
||||
! </config>
|
||||
|
||||
The exported report has the following format:
|
||||
|
||||
! <connectors>
|
||||
! <connector name="HDMI-A-1" connected="1">
|
||||
! <mode width="1920" height="1080" hz="60"/>
|
||||
! ...
|
||||
! </connector>
|
||||
! </connectors>
