The old CLK is can't link all hardware clock cell in system that the
API of layout such as 'set_parent' can't work as expected.
Some hareware clock cell need some flags to prevent some dangerous behaviors, eg:
When a clock cell is link to the PMU, the SoC will power-down if the cell is
disable.
The new CLK can do it, and make the CLK drivers implemented easier from
TRM/DataSheet.

Hardware spinlock modules provide hardware assistance for
synchronization and mutual exclusion between heterogeneous processors
and those not operating under a single, shared operating system.

What is 9PFS (https://en.wikipedia.org/wiki/9P_(protocol)):
9P (or the Plan 9 Filesystem Protocol or Styx) is a network protocol developed for the Plan 9 from Bell Labs distributed operating system as the means of connecting the components of a Plan 9 system. Files are key objects in Plan 9. They represent windows, network connections, processes, and almost anything else available in the operating system.
rt-thread could share filesystem in VM mode with 9pfs such as QEMU...
