As far as i remember the i2c elements were used for backlight on/off sequence in BYT. So can you please confirm when the display is blank are you able to see the backlight ? Also the bus number what we were using was 3, can you please try to hardcode the value of 3 for the bus number in the mipi_exec_i2c() and give a try.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
