Hi Laurent. Thanks to you, Jani, and Jagan for your replies. I'm replying to Laurent's email as it has the greatest number of discussion points. Noted that NWL DSI and Exynos DSI have undergone the conversion to bridges - hopefully I can take those as vague examples. On Fri, 2 Jul 2021 at 17:42,

Questions over DSI within DRM.

2021-07-02 Thread Dave Stevenson
Hi All I'm trying to get DSI devices working reliably on the Raspberry Pi, but I'm hitting a number of places where it isn't clear as to the expected behaviour within DRM. Power on state. Many devices want the DSI clock and/or data lanes in LP-11 state when they are powered up. With the normal ca
