[PATCH 3/4] media: dt-bindings: media: Document pclk-max-frequency property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This optional property aims to inform parallel video devices
of the maximum pixel clock frequency admissible by host video
interface. If bandwidth of data to be transferred requires a
pixel clock which is higher than this value, parallel video
device could then typically adapt framerate to reach
this constraint.
