In case DSS module is not used, DPLL_VIDEO1 and DPLL_HDMI can be still used to source other modules in the device. The OCP2SCP2 module, which serves as a L4_CFG interconnect adapter, lets user software configure the PLLCTRL for DPLL_VIDEO1 and DPLL_HDMI registers over the L4_CFG port. Figure 13-9 is an overview of the OCP2SCP2 bridge interface.
Figure 13-9 OCP2SCP2 OverviewSelection of how DPLLs are controlled is done through registers DSS_PLL_CONTROL[0] PLL_VIDEO1_DSS_CONTROL_DISABLE, DSS_PLL_CONTROL[1] PLL_VIDEO2_DSS_CONTROL_DISABLE and DSS_PLL_CONTROL[2] PLL_HDMI_DSS_CONTROL_DISABLE of the device Control Module.
