Dm8127 IPNC HDMI custom resolution change issue

Hi all:

    We are working with DM8127 IPNC with RDK 3.8 version,  we need some custom resolution of CMOS sensor capture  and HDMI output,  such as 720*480/60fps,  800*600/60fps and so on,  now we choose  "CAPTURE_DISPLAY_MODE_ON := YES"   in "Rules.make".

    such as 'VSYS_STD_480P' (720x480 60FPS progressive ED standard), we do some modifition of the code, but can not display the video by HDMI,  " TI81XX_PSP_HDMI_Driver_User_Guide.pdf" says it supports 1080P60, 1080I60, 720P60, 1080P30.    but we found it can also support "VSYS_STD_XGA_60 and VSYS_STD_WXGA_60",  but it can not support VSYS_STD_SVGA_60( 800*600/60fps),   VSYS_STD_VGA_60(640*480/60fps),  VSYS_STD_480P(720*480/60fps),  below is our source code changing:

                system("insmod ./kermod/vpss.ko mode=hdmi:1080p-60 sbufaddr=0xbfb00000");  change to ->     system("insmod ./kermod/vpss.ko mode=hdmi:480p-60 sbufaddr=0xbfb00000");

                 Int32 System_getVencMode(Int32 resolution) , we add 

                    case VSYS_STD_480P:        //steven 2016-1-21 add 480P to HDMI output
                                vencMode = FVID2_STD_480P;

          5.  \home\dm8127\Source\ipnc_rdk\ipnc_mcfw\mcfw\src_bios6\links_m3vpss\system\system_dctrl.c  中

                  Int32 System_getClk(UInt32 displayRes)  add

                      case VSYS_STD_480P:    //steven 2016-1-21 add 480P to HDMI output
                                  clkValue = 27000u;
                      break;
    

/*******************************************************************************************************************************************************************/ 

     Does the DM81XX HDMI driver only support HD standard but not support ED standard ?   We do not know where other code need to change,   or need to use 1/2 VEND clk source ?
