(1) Supported input reference clock frequencies to the PLL are 19.2/24/25/26 MHz only.
(2) Interconnect clock on DSS is CPU/4. This will range from 100 MHz to 250 MHz.
(3) When Main PLL is configured to 400 MHz mode, DSS can only support a max pixel clock of 74.25 MHz. For lower resolution displays the DSS clock can be lower than 74.25 MHz.
