 After adjusting Bank3 IDP reg[0x11] from 0x0d to 0x1d, the "false color"
 is gone.  It control PCLK polarity, thanks!

 Mitch then checked in a fix to OFW head, which was tested by Chia-Hsiu on
 both A1 (MMP2) and A2 (MMP3) motherboards.

 I haven't had OS built environment and source code yet, but base on the
 patch what Peyton send to Martin before, I believe the change is in
 drivers/media/video/siv120d.c:

                 static struct regval_list siv120d_default_IDP_regs[] = {

                         /* IDP */

                         {0x10, 0xff},

                         {0x11, 0x0d},  /* change to  {0x11, 0x1d} */

                         {0x12, 0x3d},

                         {0x14, 0x04},   /* don't change */

 Only need to modify register 0x11 form 0x0d to 0x1d
