15 The AM65x TI Keystone Display SubSystem with two output ports and
16 two video planes. The first video port supports OLDI and the second
17 supports DPI format. The fist plane is full video plane with all
18 features and the second is a "lite plane" without scaling support.
26 Addresses to each DSS memory region described in the SoC's TRM.
