The PLLCTRL_HDMI manages only the LDO power of the DPLL_HDMI. This is done by overriding the SYSRESET signal. All other power-management signals are integrated with the display subsystem power management.
The PMP is used to manage the LDO power of the HDMI_DPLL through the PLLCTRL_HDMI module.
Figure 13-19 shows the power states, which can be controlled through HDMI_WP_PWR_CTRL[3:2] PLL_PWR_CMD bit field.
The PLLCTRL_HDMI power status can be read through the HDMI_WP_PWR_CTRL[1:0] PLL_PWR_STATUS bit field.
