Sorry Miroslav. The AM335x Evaluation Module (ACTIVE) TMDXEVM3358 has display connected via i2c-0 bus to control backlight on/off, display orientation, etc.
note: it isn't about pinmux and display databus. That is connected right.
My hardware has this control connected to i2c-2. I am try to change this in kernel. The driver da8xx-fb was only the path that I took to change the configuration of display control bus from i2c-0 to i2c-2.
the software package revision is: ti-sdk-am335x-evm-06.00.00.00
