This patch will get the DT parameters of vsync/hsync/pixclock polarity, and pass to driver. Also add a debug information for test purpose. Signed-off-by: Josh Wu <josh.wu@xxxxxxxxx> --- Changes in v3: - add embedded sync dt property support. Changes in v2: - rewrite the debug message and add pix clock polarity setup thanks to Laurent. - update the commit log. drivers/media/platform/soc_camera/atmel-isi.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/media/platform/soc_camera/atmel-isi.c b/drivers/media/platform/soc_camera/atmel-isi.c index fead841..4efc939 100644 --- a/drivers/media/platform/soc_camera/atmel-isi.c +++ b/drivers/media/platform/soc_camera/atmel-isi.c @@ -1061,6 +1061,11 @@ static int isi_camera_set_bus_param(struct soc_camera_device *icd) if (common_flags & V4L2_MBUS_PCLK_SAMPLE_FALLING) cfg1 |= ISI_CFG1_PIXCLK_POL_ACTIVE_FALLING; + dev_dbg(icd->parent, "vsync active %s, hsync active %s, sampling on pix clock %s edge\n", + common_flags & V4L2_MBUS_VSYNC_ACTIVE_LOW ?
