PLLCTRL manages only the LDO power of the DPLL and HSDIVIDER; this is done by overriding the SYSRESET signals. All other power-management signals are integrated with the display subsystem power management.
The PMP is used to manage the LDO power of the VIDEO digital phase-locked loop (DPLL) through the PLLCTRL module.
Figure 13-12 shows the power states, which can be controlled through DSI_CLK_CTRL[31:30] PLL_PWR_CMD bit field.
The PLLCTRL power status can be read through the DSI_CLK_CTRL [29:28] PLL_PWR_STATUS bit field.
