how to enable the csi bt1120 input for imx6q

[nealbush]

hi  all:

  A problem has been troubled me some days, that is how to get correct data from CSI0 using bt1120  input .  my bsp is L3.035._4.1.0

I follow the patch   Patch to Support BT656 and BT1120 Output For i.MX6 BSP and patch  sii9135.patch .

the program setting is follow:

printk(" clock_curr=mclk=%d    lizb \n", ifparm.u.bt656.clock_curr);

  if (ifparm.if_type == V4L2_IF_TYPE_BT1120_PROGRESSIVE_SDR){

  csi_param.clk_mode = IPU_CSI_CLK_MODE_CCIR1120_PROGRESSIVE_SDR;

  csi_param.data_width = IPU_CSI_DATA_WIDTH_8;

  } else {

but the data is not correct .  can anyone give me a hand?  thanks.

  I have some doubt if the next patch is needed for CSI (input) case - Patch to Support BT656 and BT1120 Output For i.MX6 BSP

As for "patch  sii9135.patch"  -
do You mean using recommendations of the next thread ?

Re: Support BT1120 progressive mode in Mx6Q

If so, pin mapping is 16-bit as following :
CSIx_DAT2 ~ CSIx_DAT9 <----> C[0] ~ C[7],

CSIx_DAT12 ~ CSIx_DAT19 <----> Y[0] ~ Y[7].

In Your case - looks like 8-bit data bus is applied.

Have a great day,
Yuri

think you for your reply ! 

I try a lot of way to get data ,but not get success .  I patch the patch - Patch to Support BT656 and BT1120 Output For i.MX6 BSP ,but i do not know it is useful.

and I also reference the patch Re: Support BT1120 progressive mode in Mx6Q  .

my programme setting  is :

if (ifparm.if_type == V4L2_IF_TYPE_BT1120_PROGRESSIVE_SDR){

  csi_param.clk_mode = IPU_CSI_CLK_MODE_CCIR1120_PROGRESSIVE_SDR;

  // csi_param.clk_mode = IPU_CSI_CLK_MODE_GATED_CLK;

  csi_param.data_width = IPU_CSI_DATA_WIDTH_8;
