Making iMX6 display parallel port drive video data on SPI instead of I2C

[kunalkulshresth]

Hi,

I am trying to change device driver config in iMX6qsabreauto root to drive parallel display port over SPI instead of I2C. Any idea where it needs be modified? The parallel display port originally supports I2C interface for LCD, whereas our LCD supports SPI, so we have changed the pin mappings to have display port drive over SPI. Any clues on where exactly in sysroot to change the display driver drive on SPI lines instead of I2C line?

Thanks and regards,

KK

Hello Kunal,

The I2C interface that usually it is handle by the parallel Displays are made for  configuration purposes, not for sending the RAW information of the Displays.  Here is an appnote that shows all the files that need to be configure:
