Details

clk-div

int

 
Clock divider for LCDIF. This should be used to set the pixel clock
based on the root clock provided to the module.
The clock should follow the following formula:
(display height + VSYNC pulse width + vertical front porch + vertical back porch) *
(display width + HSYNC pulse width + horizontal front porch + horizontal back porch) *
frame rate

This property is required.
