I.mx28 9 bit data UART linux drivers

Has anyone implemented a 9 bit data UART driver under linux for the I.mx28. I have been reviewing the "MCIMX28RM" document and as far as I see it's not possible to read the 9bit from the UART register since the hardware just tells you the status of the parity bit.

Does anyone have any idea how I could do this. I need to know what the 9bit is since I am trying to interface the I.mx28 with a UART that uses 9bit data for UART
