Linux/i.MX6 support for Sharp JEIDA LCD Panel

We have a Sharp LCD Panel that we want to interface to an iMX6 NovPek board. We have the fb_videomode table filled out, but the LDB needs to be set to JEIDA mode for this panel and NOT VESA. In section 38.1.3.2 Bit Mapping of the i.MX_6Quad_6Dual_Reference Manual, it says that this is supported and in the next section is shows the LDB_CTRL register which bit to set to enable this mode.

 

How do I tell the driver to set this mode?

 

It seems logical that the VMODE parameter of the fb_videomode table would be the likely place for a flag like FB_VMODE_JEIDA.
