Hi,
i.MX91/93 support a parallel display interface. There is a single register
for configuring the output format. There is not much documentation, but
apparently this does some internal conversion.
Add a bridge driver (similar to fsl-ldb.c) for connecting a bridge/panel
to lcdif.
I'm a bit unsure about the name. There is no dedicated IP, according to
reference manual, just that single register. I would also agree
to imx9-dpi or imx93-dpi.
Note: It's only applicable to i.MX91/93, but not i.MX95!
Tested on TQMa9352 on MBa91xxCA
Best regards,
Alexander
