[PATCH v2 00/22] Add basic clocks and resets for JHB100 SoC

[Changhuang Liang]

The JHB100 SoC includes CRG (Clock and Reset Generator) for multiple
subsystems:

The JHB100 SoC is divided into multiple subsystems, and basically
each subsystem includes a CRG(Clock and Reset Generator):
 - sys0crg/sys1crg/sys2crg/
 - per0crg/per1crg/per2crg/per3crg/
 - voutcrg
 - vcecrg
 - gpu0crg/gpu1crg
 - cpucrg
 - usbcrg
 - host0crg/host1crg
 - pcierpcrg
 - husb0crg/husb1crg
 - husbcmncrg
 - husbd0crg/husbd1crg
 - npucrg

In the current series, we will only add the following CRG:
 - sys0crg/sys1crg/sys2crg/
 - per0crg/per1crg/per2crg/per3crg/

The remaining CRG will be implemented in future series.

This series depends on the series:
https://lore.kernel.org/all/20260506085937.754808-1-changhuang.liang@starfivetech.com/
and it has been tested on the StarFive JHB100 EVB-1.

changes since v1:

PATCH 5/7/9/11/13/15/17/19:
- Create contiguous reset binding IDs.
- Make the naming of some clocks more meaningful.

PATCH 6:
- Add a common helper function starfive_crg_probe().

PATCH 6/8/10/12/14/16/18/20:
- Use starfive_crg_probe() to register the CRG.

patch 21:
- Add reset_starfive_register_with_info() to support both
  contiguous and discontiguous reset IDs hardware designs.
- Create a mapping table for discontiguous reset hardware
  IDs.
- Make RESET_STARFIVE_JHB100 under COMPILE_TEST.

patch 22:
- Fix the fixed-clock node names.
