rv1126 架构如下
mipi csi phy media相关注册代码如下：
enum mipi_dphy_rx_pads {
MIPI_DPHY_RX_PAD_SINK = 0,
MIPI_DPHY_RX_PAD_SOURCE,
MIPI_DPHY_RX_PADS_NUM,
};
static int rockchip_mipidphy_media_init(struct mipidphy_priv *priv)
{
int ret;
priv->pads[MIPI_DPHY_RX_PAD_SOURCE].flags =
MEDIA_PAD_FL_SOURCE | MEDIA_PAD_FL_MUST_CONNECT;
priv->pads[MIPI_DPHY_RX_PAD_SINK].flags =
MEDIA_PAD_FL_SINK | MEDIA_PAD_FL_MUST_CONNECT;
priv->sd.entity.function = MEDIA_ENT_F_VID_IF_BRIDGE;
ret = media_entity_pads_init(&priv->sd.entity,
MIPI_DPHY_RX_PADS_NUM, priv->pads);
if (ret < 0)
return ret;
...
}
mipi csi phy有2个pads，一个source pad，一个sink pad.
