HI  :

 

      I found that , there is two descriptions about pll in imx8mm dsi:

 

what's the relation of them ? The "DPHY PLL" Fout max is 750M only, but PLL up to 2.1G.

And in linux-4.14.78, if DSI is connected to a panel, the PMS is hard code to 0x4210(In this setting , the output of DSI clock is 445.5Mhz), what should I set if panel's pix clock is 148.5Mhz (I have tried function sec_mipi_dsim_get_pms(dsim->bit_clk) in 4.14.78, the DIS output clock is the same 445.5Mhz)?

 

Best 

Regards
