I am trying to interface a 480x272 LCD to an I.MX6DL over LVDS, but am running into problems with configuring the pixel clock in Linux.
The display I have requires a Pixel Clock of 9.5MHz, but I am unable to achieve rates below 20MHz.
Out of the box, it seems Linux wants to use PLL2_PFD0 which does not support pixel clocks below 33MHz or so. Reading other comments on the Community site suggests using PLL5, but through experimentation, I cannot achieve rates below 18MHz.
I do see in other posts where others were seeking a similar objective, but I do not see any direct responses indicating the changes needed or patches required.
Has anyone configured a low frequency pixel clock on the i.mx6?? How can this be done???
