+The Hisilicon Djtag in CPU die is an independent component which connects with
+some other components in the SoC by Debug Bus. This driver can be configured
+to access the registers of connecting components (like L3 cache, l3 cache PMU
+ etc.) during real time debugging by sysctrl. These components appear as child
+nodes of djtag.
+
+The Hip05/06/07 CPU system controller(sysctrl) support to manage some important
+components (such as clock, reset, soft reset, secure debugger, etc.).
+The CPU sysctrl registers in hip05/06/07 doesnot use syscon but will be mapped
+by djtag driver for use by connecting components.

+The Hisilicon HiP05/06/07 ALGSUB system controller(sysctrl) is in IO die
+of SoC. It has a similar function as the Hisilicon HiP05/06/07 CPU system
+controller in CPU die and it manage different components, like RSA, etc.
+The Hisilicon Djtag in IO die has a similar function as in CPU die and maps
+the sysctrl registers for use by connecting components.
+All connecting components shall appear as child nodes of djtag.
