Hi Liu Ying: I foud Rockchip RK618 (a mfd function device with mipi dsiï¼lvds transmitterãHDMI TXãand audio codecï¼and controlled by the SOC from i2c ) have the same register layout with your i.MX MIPI DSIï¼which means RK618 MIPI DSI also have the Synopsys compatible DSI IPãSo Would you please make this drives more platform independentï¼
