Hi

I want to add support for 1280*800 and 1366*768 resolution with hdmi display on imx8mq. By reading the code,I found the pixel clock 85.5M(1366*768) and 71.1M(1280*800)  was not  supported. i am afraid  i shouled modify table 8(t28hpc_hdmitx_clock_control_table_pixel_out[]) and table 9(t28hpc_hdmitx_pll_tuning_table_pixel_out[]) to support 85.5M and 71.M. and I have read the IMX8MDQLQRM datesheet. and it does not describe about this. How can I to config these tables?
