DSI PLL sample code?

As written in previous mail, it seems that we can't get pixel clock > 72MHz with DPLL4 without e.g. breaking 96MHz clock. Somebody mentioned that it could be possible to configure DSI PLL to create max 173MHz clock to create max 86.5MHz pixel clock.

Anybody with DSI PLL sample code, ideally programming it to 173MHz? Or any other hints?

Thanks

I'm interested in this as well. Sadly, I haven't figured out how to
make it work.

has

dsi_pll_config()

Wonder if anybody already did something like

for beagle and if it will do 1280 x 1024 :wink:
