The subsystem has one reset input for each of the AXI4-Lite and AXI4-Stream interfaces:

s_axi_cpu_areset
Active-Low AXI4-Lite reset
s_axis_video_aresetn
Active-Low AXI4-Stream Video interface reset
s_axis_audio_aresetn
Active-Low AXI4-Stream Audio interface reset
m_hdr_axi_aresetn
Active-Low Dynamic HDR memory mapped AXI4 interface reset.

Note: There is no dedicated hardware reset for the NATIVE_VID_IN interface when Native Video or Native Video (Vectored DE) interface is selected. However, the HDMI 2.1 TX Subsystem outputs a video_rst signal, which you can use to reset its Native Video or Native Video (Vectored DE) Source generation modules.
