DRA726: Need a work around for an LCD hardware design issue

Part Number: DRA726

I found out last week that an error was done on our boards that we will receive Friday.

Red and Blue colors were swapped for the LCD connection to the RGB to LVDS device.

I see that it may be possible to do a color swap but details on how to do this are not clear to me.

There is a hardware block in the display subsystem called "Color Phase Rotation Unit".  It is documented in the DRA72x TRM in Section 11.2.4.13.3 "DISPC Color Phase Rotation Unit".

There is a function in the dss driver that can change the registers (dispc_mgr_set_cpr_coef)

How can we use this to do the color swap?
