We're using a MIPI DSI display (controller is ili9488) with imx6dl and are experiencing problems reading registers from the display. After the read command has been sent by imx6 a bus turnaround is also sent, the display then starts to transmit, but it seems as the imx6 then also transmit at the same time, causing a bus contention.
Any ideas of what is causing the imx6 to transmit at the same moment as display?
Is there some timeout in imx side causing this? Can the time be extended.
The driver is based on mxcfb_hx8369_wvga.c on Linux 3.14.
