The CSI_TX_IF links to the DPHY_TX clock and data lanes. After power up, software must identify that the DPHY_TX is powered on and the DPHY_TX PLL has locked. The DPHY_TX controls for swapping the DP/DN control can be modified using the CSI_TX_IF_DPHY_CFG1 register if required.
Software must then program the enable for the clock lane and each data lane that is required. The DPHY_TX lane signals can be checked using the CSI_TX_IF_DPHY_STATUS register to identify that the lane is in STOPSTATE and is ready for High Speed transmission. This register can also be used to identify when ULPS is active.
