[PATCH 07/35] drm/amd/display: update pixel clock params after stream slice count change in context

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

 



From: Wenjing Liu <wenjing.liu@xxxxxxx>

[why]
When ODM slice count is changed, otg master pipe's pixel clock params is
no longer valid as the value is dependent on ODM slice count.
