Hi Jean-Philippe, I finally create my patch against f5cef8f45739db4c0c1c346296922cac274c87eb in attachment, but the problem is that isif_set_hw_if_params is not called by gstreamer.
If I set in drivers/media/video/davinci/isif.c (and not in
drivers/media/video/davinci/dm365_ccdc.c as I don't have it !!)
'ycswap=YCIN_NOT_SWP'
it works !!
The board file has no effect on my gstreamer command:
gst-launch v4l2src ! video/x-raw-yuv ! filesink location=video_new3.raw
see below for my complete logs.
Here you are the board declaration:
static struct vpfe_subdev_info vpfe_sub_devs[] = {
{
.name = "adv7180",
.grp_id = 0,
.num_inputs = ARRAY_SIZE(adv7180_inputs),
.inputs = adv7180_inputs,
.routes = adv7180_routes,
.can_route = 1,
.ccdc_if_params = {
.if_type = VPFE_BT656,
.hdpol = VPFE_PINPOL_POSITIVE,
.vdpol = VPFE_PINPOL_POSITIVE,
.ycswap = YCIN_NOT_SWP,
},
.board_info = {
I2C_BOARD_INFO("adv7180", 0x20),
.platform_data = &adv7180_pdata,
},
},
};
The patch is very similar to yours, I change only the name of defines
because they seem more clear to me.
The complete log (setting ycswap=YCIN_SWP inside isif.c file in order to try
to get the correct parameter from my board file) follows:
(isif_set_hw_if_params is not called)
